Someimes My Nexus One won't send text messages or make phone calls unless I reboot :(

I have an unrooted ATT version of the nexus one. Randomly about 1 or 2 times a day while I am texting I will get a failed to send message and no matter how many times I try it just keeps failing. It won't allow me to send texts to anyone else either. however I continue to receive texts which is kinda odd.... the worst part is that always while this is happening I cannot make or receive phone calls this is very frustrating since I could be missing phone calls and wouldn't know it until I try and send an SMS or make a call. I have tried a lot of different things such as setting my bands to USA and setting my network preference to WCDMA Only but to no avail... I also tried a factory reset... also if I try and toggle airplane mode or turn off the radio it just crashes and I need to reboot.. if i try checking the SMSC while this is occurring but hitting the refresh button
I get refresh error and if I try and update it with the correct number I get update error... I really love my N1 and would really appreciate anyone who could shed some light on this issue

Re: My Nexus One won't send text messages or make phone calls unless I reboot
Could this be an AT&T network issue? I had similar symptoms with my HTC Hero (admittedly running EDGE) in certain parts of San Francisco earlier this year. It seemed to be the result of network congestion. Does this occur in a city or other urban area?

I am actually not on AT&T I am on Rogers network in Canada. I am living in Toronto so the 3G coverage is really good and I`ve never had this kind of issue with my previous phone which was a BB9000 and none of my friends seem to have any of these problems
I also found ppl on some other nexus one forums describing the exact same problem which leads me to believe its not a network issue but I am still not 100% sure I tried calling Rogers and had them do a cancel location and it didn`t fix the issue either

I had this issue only this morning and I'm in the UK, I put the phone into Airplane mode and back again and then everything is fine.

I have this issue about once a day.
Running the newest Cyanogen with no other modifications. Radio is the most updated one available.
Flipping to Airplane mode and backed worked on my G1 if I had an issue similar to this but the Nexus doesn't respond to it.
I reboot atleast once a day to fix this. -- Not sure if it's the radio or Cyanogen.
Anyone else have some input?
EDIT: Should have included, I am on T-Mobile

This actually happened with me today, a text kept failed and didn't get pushed through until I reset the phone. I'm hoping this doesn't turn into a daily thing

next time this happens if it happens again could u guys try and make a phone call before resetting so we can see if our problems are identical?
Thanks

This sounds like a problem I have had for several months now on T-Mobile (I just bumped the thread under the "General" topic to see if there were any developments, as I've been away from the board for six weeks or so). The symptoms I have are that the signal strength icon in the status bar shows zero bars with an "x" and the home screen says "No service." When I attempt to power off, after a while the spinning arrow stops spinning, the trackball flashes once, and then the phone reboots (takes about 45 seconds to a minute after I initiate the power-down before the reboot starts).

Same thing happened to me today. I'm on a stock unrooted AWS version of the N1.

I am unable to make phone calls, send texts, etc. until I reset. It has no impact on Wifi but kills the cell network completely.

I also have a long delay after hitting restart when I get this issue. Maybe Ill try to get a logcat and see what it gets stuck on..

I'm getting RMA'ed, again, for the same issue plus not being able to register on the network after I get the x with four blank bars. I get either "error searching for networks" or "sim is invalid on this network". It's since fixed itself... somehow but i was without any phone service despite trying everything (calling tmobile for network outages, hard reset, reseating the sim card, other stuff) for about 3-4 hours twice now... and a few shorter time periods (1-3 minutes of those errors) before that.
Possible solutions.. which I've only done after it started working again but didn't cause anything bad to happen. So far have been without any of the previous issues, plus my original long standing issue of not being able to send texts, get any sort of data, or call (I call it the up arrow without a down arrow problem where the phone is trying to connect but doesn't receive anything back). These solutions were originally posted here:
http://www.google.com/support/forum/p/android/thread?tid=3f4ad5ffac46bf92&hl=en
http://www.google.com/support/forum/p/android/thread?tid=47dc569ca9667ba7&hl=en
They're also solutions I've come up with for my issue as well and seemed to have worked for a couple of others.
It's as follows:
*#*#4636#*#* and selecting phone information. Press the menu button and select the proper band. I'm guessing if you're in canada on rogers which uses the same band as AT&T US you'd select USA band. Anyway after selecting it should re register on the network.. close out of there. Turn off and turn on the phone and see how that goes. For people in other regions I have no idea what to properly select but it was posted on one of the threads on the google forums that it should be "automatic". Check with your provider and/or google tech support.
Another thing I've seen is again in the *#*#4636#*#* menu under phone information put in (THIS NUMBER IS ONLY VALID FOR TMOBILE USA) under SMSC 12063130004 and press update. Call your provider for your number. Restart the phone.
Less likely solutions (in order of descending likeliness to help you in your particular case):
Hard reset and/or verify the APN settings for your carrier. I've been told non factory default APN values for tmobile over the phone (google support) so I don't know if verifying them or asking for them will help or cause more issues but sometimes there's apps the mess with the APN values which could cause some of your issues. So while this has a high potential to help, it's easy to screw up. Hard resetting the phone will give you factory default values (I'm 99% certain but from what I remember). Changing them from non factory default isn't a terrible thing however call your provider rather than google tech support for the values.
Calling up and asking to add/verify the IMEI number to the network (i never did this until recently although it didn't fix my issue right when they added it anyway) and/or doing a network cancellation might help. Unlikely but if you' RMA'ed once they'll have the wrong one on file and could cause issues depending on the network.
Replacing the SIM card. Takes literally 30 seconds. They ask for account info at the store, they scan the new one.. and give it to you. You pop it in and go. If you have an older SIM card this DEFINITELY could be the issue. Its unlikely its defective but it's always worth ruling that out.
Let me know if any of these help.

I`ve tried all the solutions u`ve mentioned except for swapping to a new SIM card... I guess it might just be my next step but I have my doubts

I get this kind of issue occasionally, under these specific conditions only:
1. I'm at work.
2. I bring my phone with me into an area with no signal (screen says no signal, and I have 4 blank bars with an X) for more than a couple of minutes (for me, it's the room with the coffee machine - which I use a lot - no provider gets signal there on any phone).
3. It doesn't always happen, just sometimes, but when I go back to my desk, it won't reconnect.
4. Going into and out of airplane mode fixes it every time. However, with the latest CM and Ivan's Diet kernels, going into and out of airplane mode causes an immediate reboot when I try to come out of it, and only when I'm NOT connected by USB and when I AM coming from "dead" service, making logging the problem, well, problematic. Using other kernels (even OC'd kernels) does not seem to cause this airplane mode problem.

Only had this happen once trying to send a plain old SMS. I restarted the phone and no problem. I didn't think of trying to make cell calls, but if it happens again, I'll try that.

I too have had this issue with SMS. My browser works though when the SMS problem occurs. Haven't tried a phone call. I am on T-Mobile USA.

Are any of you using task-killers that may somehow be interrupting an important background service?

I have the same exact thing happen and I am on T-mobile US. I was hoping that I wasn't the only one but it seems to happen on all of my phones so I have just chalked it up to network congestion. Unless someone has an actual answer.
I have this issue about once a day.
Running the newest Cyanogen with no other modifications. Radio is the most updated one available.
Flipping to Airplane mode and backed worked on my G1 if I had an issue similar to this but the Nexus doesn't respond to it.

This helps with the switch from Edge -> 3G -> H.
I wonder if it would fix this issue.
I don't have the issue so I am unable to test myself.
This link may help. Its at least something to try.

I am using Advanced Task Killer Free, but I'm pretty sure I added important background services to the ignore list so they shouldn't be killed.
Just to double check, what background tasks shouldn't be killed?

Nexus one not reconnecting to mobile network

My N1 will not reconnect to a mobile network if it has been sitting for a few hours in a no-coverage area, such as a building. I cannot get it to reconnect, even after refreshing the network search. This action only leaves me with no result or a message saying that there was an error in searching or connecting to mobile networks. The only solution is to restart the phone. Every time I try to turn the phone off after this error has occurred, the shutdown sequence hangs until either I become frustrated and do a battery pull, or it automatically restarts and do a battery pull, or it automatically restarts itself. Furthermore, the phone used to give me an error notification saying that the phone does not have carrier service. Now, it does not. Furthermore, the phone used to give me an error notification saying that the phone does not.
I tried uninstalling all my programs and nothing has worked for me. I've also tried toggling the airplane mode to no avail.
I'm considering putting on the cyanogen ROM to see if it would fix this error, but I am hesitant to void my warranty. It's a pretty serious problem as I'm very frequently in a building where I don't get service. It's quite frustrating to have to wait to reconnect to a mobile network once I leave the building and hope that the error didn't occur or have to do a battery pull every time I realize that the phone simply won't reconnect.
Can anyone suggest any solutions?

Mod it. What have you got to lose? Your overall performance will increase. The radio signal may even improve. Your call.

thanks for the tip. i've been thinking about it. it's the warranty i don't want to lose. eh i'll keep thinking about it.
this phone sucks. it's glitchy, can be sluggish. iphone got dumbed down but at least its functions work.

Hey!
You dont want to lose your warranty, then use it!
Your phone seems to be faulty...

My phone is experiencing the same problem as of yesterday. Won't connect. Wonder if it's a T-Mobile issue.

Its only glitchy coz you have stock rom
Cyanogen is really stable and adds alot of features / functionality.
Fair enough you dont want to lose warranty but i remember in the general thread that lots of hardware failures and others can still fix your n1 under warranty even though they unlocked the bootloader.

I too have this problem, hopefully the 2.2 update will fix the problems.

Can you guys confirm if its android or your service provider thats causing this...

I have the same problem and it's starting to bother me a lot because my car is parked in a garage with no coverage. My in-car BT then becomes useless as my phone won't reconnect to the network once I exit the garage
I just called Google support 10 mins ago about this and they went through normal protocol to reset to factory settings. They then called Tmo and let them know what the issue was while I was still on the phone. Tmo unregistered my phone from the network while my battery was taken out of my phone and then reregistered my phone to the network. Tmo asked me to monitor this for a few days and call them directly (not Google) if the issue persists. They will then elevate this to a higher level because they feel this would be a network problem, and not a hardware issue.
Hope this helps! Please post what you have tried to solve the problem!

^ it worked! my phone reconnects to the cellular network after what Google/Tmo did for me on the phone!

I haven't tried calling tmobile, but it is NOT something that will be fixed by hopping on cyanogen's rom. I've been rooted on cyanogen's rom for quite some time and this problem still exists on my n1 which is SUPER annoying. I will try calling tmobile to see if they can fix it on their side, but rooting is not the fix here.

I had the same issue. I used anycut and phone info shortcut and changed the wireless default setting to us and it totally fixed the problem. Have not had that issue again.

I resolved this by going to the T-Mobile store where they replaced my SIM card. They made a copy to a new SIM card, installed it and everything works fine.
For the record symptoms included:
* "Error while searching for network" message
* Found networks but said "your SIM card is not authorized for this network" when connecting
* Network listed as "No service" or "Emergency calls only | T-Mobile"

I get this too with an at&t phone.
Have asked for a replacement device from HTC (since the reception is crappy to begin with).
I also have audio quality problems when reception is only 1-2 bars.
Will see if the new phone is better.

I had this problem regularly. It hasn't happened once since I upgraded to Froyo, so I think it has been fixed in that release.

sometimes have this too, i fix it by going to the settings > wireless > mobile networks > APN. at first i deleted and retyped my password in the selected APN, now i just click my network in the APN settings, don't change anything and leave. It immediately reconnects after that.
edit: and i have stock froyo & live in belgium.

I got a new, replacement phone from HTC today.
This new phone has a BIG PROBLEM with this issue.
Even if I am only without reception for a couple of seconds (go through the garage, etc.) it will not connect to any network until I reboot.
My old phone would only experience this problem maybe 25-35% of the time.
Very, very annoying!!!

I had similar issues and called tmobile support. I was first linked to Google support. They went through the similar process as described by in the first page. (#*#*4636*#*# select USA band etc). While I was on hold, they called t mobile tech support and had them reset network connection and tried to get me onto a different tower etc.
Tmobile support stated that my sim card (had for about 2 years) was the cause of the issue as they can't handle smartphones as well as their new sim cards. They also said the new sim should improve reception and connection stability (Don't see how a new sim could do this but what do I know?). Moreover, they noted my account and told me to go into the nearest store for a new sim card. Went into the nearest tmobile store told them the issue, they pulled up my account and gave me a new sim. Took less then 5 minutes and I have not had the issue with staying connected to the tmobile network.
I will update this after a few days to see if I still have the issue.

I have the same problems that i cannot connect to network here in germany. first i think it was my sim card, but befor i had another provider (E-Plus) where i had the same problems with reconnecting to network. and one day my eplus sim card is broken so i had to buy a new one by t-mobile. i have tried a lot of roms from here (cyanogen/ 5.0.7 /5.0.8T5 Kangorama rodriquezstyle and leofroyo) everyone seems to have the same problems with reconnecting to network. i hope im not alone with my problems and someone can help.

hmm...
Count me as another. I just upgraded to froyo and it went beserk. Had no service for a while. It would only come on after constantly tapping "select network automatically" until it kicked me out of the menu. It started getting better but kept kicking me out of 3g. I set it to stay always on 3g and it seems to be better... still I'm going to call tmobile and see if I can get a new sim as well.
Thanks for the info guys!

WEIRD! Emergency call only! O_o

This one is pretty *beep* up! The phone was working pretty fine last time I looked at it (30 minutes ago), I put it in my pocket and had dinner (as always), then I took it out to make a phone call and it says just "Emergency call only" instead of showing my phone operator (3 ITA). I tried rebooting, no luck! Still the same.
Strange thing is that it has signal (full) but I can't make/receive calls or use data network. If I go under Settings -> Wifi -> Mobile networks settings and I look for operators it searches and I can see all of them (mine included) but I cannot select it!! Neither mine nor another one (TIM, which is the roaming default one for my operator when there's no signal)...it just says "Unable to connect. Try later".
Weirdest thing of all is that I AM RECEIVING PUSH EMAILS from gmail!!!
Anyone has a clue about this??? Has it ever happened to anyone?
Btw, I'm using zeroblaster rom, which is based on official italian froyo firmware...everything was working so good until ten minutes ago!
Hope I don't have to reflash...

Just got weirder: put my sim on another phone...it registers without problems on the network.
Then put the other's phone's sim on my sgs...it registers without problems.
Then switched again: Emergency calls only
WHAT THE ****??!? (what are we? children? sorry mod...lol)

It is WAY weird imho! The weirdest thing being that I'm still receiving gmail's pushes after 5-6 reboots while it keeps saying "emergency calls only".
Also I saw that when the phone boots, while it's loading the launcher, widgets, etc. it gets the connection for like 2-3 seconds it shows my operator (in the lockscreen), then it switches to "emergency calls only"...
I'll wait another hour (maybe as the issue came out of nowhere it'll go away? ) then I'll try reflashing...since I had to change to k9 anyway to fix the /system corruption etc. -.- I'm already backing-up...
Hope the flash will fix this though...it's really a pain in the ***

No that's not it, because putting H3G sim on another phone WORKS!!
And anyway, when H3G's down it uses TIM as roaming...this time I cannot even select TIM as operator, it refuses! And normally you can always use tim in roaming if you want (even when H3G has signal...)!

Hmmmm... That is weird alright.
If you purchased your SGS through your carrier H3G I would still call them to report it as there are now 2 of you experiencing the same issue so it cant just be phone related and if it is then they will have to honor your warranty to replace or fix it (both of you)...

It's happening to me too.. i also use H3G Italy on my Galaxy S and i have this issue since around 19:00 this evening with my work SIM card
I have a Tayutama 1.0.0 ROM based on the JPM Froyo ROM.. it's the first time this is happening to me..

Well... That is 3 of you so it must be carrier related in some way. Again... Call your carrier and explain what is happening. Explain that when you put the sim into a different device it works ok but in the SGS all you can do is make emergency calls and they should be able to tell you what is going on.
Make sure to post back as I am now interested in seeing what your issue is / was...

service state: out of service
mobile network state: connected (and it works... )
but ... int the status bar it shows "Only emergency calls"...

You just answered your own question I think. "service state: out of service" says it all I believe even if the sim cards DO rgister on another phone for whatever reason.
The fact is the they dont register on your Galaxy S so call them and report the issue and they should be able to help you...

Yeah well, you see, that could be a problem because...H3G has a TERRIBLE customer care, lol! Basically the thing is you can't call them...you need to send an email, and an answer will arrive 2-3 days later. That's not good enough for me! If it doesn't get fixed tomorrow I'll go directly to a 3shop and they'll call someone higher to understand this. Hope they fix it soon though!
Anyway...now I have a strong curiosity: could it be JUST the SGS? If so...WHY???? I tried putting the simcard on a Nokia E71 and it works...does anyone have another android phone with H3G? Could it be somehow "system"-related? Because I can't figure out why a specific phone device shouldn't work point-blank with my operator! And that's even a phone they sell themselves!!

Rebooted and now it WORKS! THANK GOD (even if I'm atheist....)
Still would like to know why it did this!

I had a similar problem where if I was in an area with bad reception it would default to emergency calls only. But the funny thing is when I go into the menu settings I can see my carrier and when I try to select it, it says network unreachable. Eventually I would get signal but the tab still says emergency calls only. Tried making calls but it wouldn't allow.
Initially to rectify the problem I rebooted the phone and that worked but got annoying. So I realised that if I left it for a couple of mins whenn it had reception it would fix itself. As of recently (last 2 months) I haven't any problems.
Btw i'm on jpm and my carrier is 3 australia. It's rubbish service

Hello,
Same thing happening to me... It must have something related to signal strength, i went downtown and phone was perfectly fine.
But at home it keeps loosing signal, i dialed *#*#0011#*#* and it shows changing BAND... as if it was searching for service on different bands...
But the thing is, i tried inserting the SIM on other 2 phones and i get a FULL signal, so i guess signal is coming pretty intense here... why is the SGS loosing it? i have no idea...
By the way, i am from Brazil, and that started happening after i flashed my rom to FROYO VJJPA..

me too, has no signal at home but works for another phone.

Enable Data Roaming Setting Not Retained

Like many others, my phone has a tendency to drop 3g unless I enable Data Roaming. This has been the case with My D1 with 2.3.3.
Now that I have the Droid 3, I have the same thing. No surprise there.
HOWEVER, when I enable Data roaming on my D3 and then go into an area where the phone drops to 1x then no data, I get a notification that Data connectivity has been lost because Data Roaming is Disabled.
If I pull down the notification bar, it says I can select the bar to go to the setting. I do. Sure enough, the Data Roaming Enable box is Unchecked.
I check the box. Go to my home screen, and the notification will reappear. I can do this all day.
If I go to my home screen, ignore the notification and go to settings, battery & data manager, then data delivery, the setting is unchecked....BUT....If I access the menu this way; the setting will be retained until the phone is brought to an area where data signal does the 3g to 1x to no signal thing. Then it starts all over again.
Any suggestions? Anyone else getting this? I received my D3 over a week ago, and finally exchanged the phone for another one. That phone lagged and had random freeze issues. This phone has none of those issues, but still has the Data Roaming Enable setting not retained problem.
Wasn't this an issue with CM7 at one point? The d3 claims to be running 2.3.4, but it is hard to tell with all the Motoskin draped over it.
I have also noticed that (in my area) if I have data roaming enabled, my battery life is much improved. With it off, my battery drops like a rock.
I have contacted Moto about the issue and reported the bug; but all I am getting is the "we'll look into it" brief email. Like I'm some kind of first-time Android user who doesn't know how to use my phone.
Please tell me someone out there is having this too, or that there is a patch that Moto just hasn't released yet....
Thanks in advance everyone.

UPDATE:
2nd phone, all data connection is lost. No phone, 1x or 3g. Phone is awake, and battery settings are set to Performance (No Battery Savings).
Data manager is disabled (no stoppage of data)
When going into an area where I ALWAYS had "EXTENDED NETWORK" data available at 1x speeds prior to this phone, the phone says no data connection.
I look and my Data Roaming Enabled checkbox has been unchecked.
I check the box, click OK to agree that I may incur Roaming charges. The phone will reconnect to data at 1x or 3g depending on where I am.
If I look at the phone 5 minutes later, the checkbox is Unchecked again for allow data roaming. Sometimes less.
This only happens after the phone goes into a weak coverage area.
I have tried rebooting the phone. The setting stays retained after reboot, but is lost as soon as I go into poor coverage.
I have tried factory reset. Setting stays until I reach a poor coverage area.
Already exchanged for another phone. Same issue.
Changed phone from Global to CDMA mode and network to automatic. Setting still does not hold.
It is most strange though, that it doesn't happen until after my home network is lost. The setting will hold until then.
Without that setting checked, I cannot connect to my "Extended Network", which in my area is a no-cost option. I keep checking the box, only I can't get the setting to stick when I go to a weak coverage area.
The coverage area should not make changes to the retention of allowing of data roaming checkbox. Something is improperly referenced in the software.
Motorola's out-of-country sweat-shop customer-no-service department wants me to ship my 2nd brand new phone to them (5-7 days for them to process and receive it+whatever it takes to ship to them) and take between 14-21 days to "repair" the phone, and then take another 5-7 days to package, ship and return to me (all at my expense). Why am I sending a new phone that is defective "out of the box" to be repaired??
So I'm supposed to go without my phone for 5 WEEKS because they have a software problem??? It can be duplicated every time, and on more than one phone. They have the old one. Fix that and send out the update please!!
Am I the only one that has had this issue? Seriously, no one else?
Any help would be greatly appreciated. This is frustrating as heck. I love the phone, but this is ridiculous and makes it rather un-usable depending on where I am. I NEVER had this with my D1! Moto, what happened?
Thanks everyone. +1 if you've had the issue please.

Same Problem
I also have this same problem.
After reading other forums, I thought it may just be the Droid 3 or a Motorola problem. I ended-up turning back in my Droid 3 after Motorola said it was a Verizon problem (which really is not the case). Now, after reading your thread, it makes me wonder if this is a Android OS issue.
I really hope it is not a OS issue, I have wanting an Android phone for a long time.
At my house it always kicks off the data roaming option. I really have no idea what is causing it.
Just wanted to post so that you know your not the only one!

Thank you.
I have run a logcat and have traced the problem to Motorola's battery and data manager service. It is not the OS itself, from what I can see.
It seems that under these particular conditions, the battery and data manager service crashes. Though this should not be a major problem in and of itself, though still not right and needs fixing there too. The service promptly restarts and then loads the settings that were enabled at the time of the crash from a secure data folder. (Or it's supposed to)
The problem comes into play when these settings are loaded. Enable Data Roaming is "loaded" as No(off) any time the service loads these values after a crash of the Battery and Data Manager service.
Unfortunately, as usual, Motorola is dragging their feet at releasing the source code for the Droid 3. This may or may not help the issue, as the Battery and Data Manager service that crashes is a part of Motoblur. Meaning, they aren't going to be forthcoming with the information.
They also are being a typical OEM in their refusal to believe that they could have made a mistake when programming and that they have something to fix.
My Droid 1 has run 2.3.3, 2.3.4, and 2.3.5 and this has NEVER been an issue keeping the setting retained. This is not an issue on our INC2, which is running 2.3.4 in all the same areas that cause my D3 phone to lose the setting. I am also running an Eris with 2.3.5 and it does not have the issue. This is strictly with the D3 from what I have seen.
It's funny how Moto is blaming Verizon for an issue they say doesn't exist. If there isn't a problem, how can that be the network's fault??? The network doesn't change that setting in the phone. Software changes it. In this case, poorly written software added onto the Android OS. Too bad, the OS works fine until Moto putzed with it (Blur).
The OS is not the issue here, it seems the D3 software has two problems:
1 the Battery and Data Manager service shouldn't crash like that.
2 it should return the proper settings if it does.
If I had the chance to do it all over again (knowing what I know now), I would have said send me an INC2 as a replacement. I honestly figured it was a phone hardware problem and the new phone (under warranty) would fix it.
Honestly, I am completely disappointed with this device. That may change when root is obtained and I can get rid of the poorly written trashware that seems to plague this phone. But right now I'm most disgusted with the fact that it doesn't work right and Motorola couldn't care less, even though it's their sofware that is the problem.
I have pruchased my last Motorola product, and am not holding my breath that Motorola will either care or fix their problem. I am certain the future rooted ROMs will be able to transform this lagtastic, glitch-ridden, battery pig into the elegant piece of hardware it has the potential of becoming.
Sorry Moto, sometimes the truth hurts.
Thanks for the support that it isn't only my phone or service area.
Others please +1 as you experience it. The issue is logcat documented and now confirmed on at least 4 devices.

I have this issue as well. Now that we have root, do you have any ideas on how to resolve it?

This is the response I received from Motorola. They need to get a move on with a fix for this huge goof up.
"Thank you for reaching out to Motorola.
We apologize for all the inconvenience and appreciate your patience. The Support Engineers have been made aware of the issue with the "Data Roaming" feature of the phone; and there are currently working on a possible resolution for a future update. You will need to manually change the roaming option back until fix is available. The Support Engineers have not provided an ETA on when this will be available.
If you have any additional questions or concerns please contact Customer Care at (800) 734-5870."

The latest developer update, which is currently in soak testing, has fixed the issue for me.
No formal release date yet on the over the air (ota) version's release date, but I would expect out in the next couple of weeks as long as everyone else had the same results I had with the test update.
Update will upgrade system version from 5.5.959 to 5.6.890, and the baseband radio will be updated at that time as well as the kernel.
So there does seem to be a fix, despite the terrible customer service at Motorola. Honestly, it sucks! I had this update last week, and I'm sure somebody knew this was intended to fix the problem. Not once has Moto asked for information or applied for releasing a phone that was not ready.
Instead, we got canned bot responses and the general feeling that Moto just doesn't care now that they have our money. It is really sad.
Lets hope Google can straighten it out.
Fingers crossed. Though now that we have root, and a custom recovery possibly by week's end; I could care less about Moto. My next phone won't be Motorola...fool me once, shame on you; fool me twice, shame on me.

I have also flashed to 5.6.890, re-rooted and de-bloated. So far, the new radio has done nothing to help my issues with the data roaming becoming disabled. Have you tested the new software under the same conditions as the old?

I may have to retract my last statement... my phone did auto disable the Data Roaming once after updating, but since then it has been fine. Hopefully the update truly did fix it!

I have purposely tried to get the setting to fail. Same result for me as you saw; I got the same old warning once and have not seen it again in over a week now.
For me this was huge, as it failed 20 plus times a day at work. All I had to do was walk down one specific corridor, and by the time I got to the other end my setting would have been unchecked. So going a week with it staying retained (in global mode too by the way) is monumental proof for me it is fixed.
Now I have seen this on the D2 global twice this last week. They don't have a fix yet either, but technically this one isn't official until it's pushed ota.
Good luck all. More news as I have it.

I can't STAND this problem! Happens to me every day at work. Heck, even if I had a widget button that I could turn on the data roaming with from my desktop would be better than having to go into settings everyday
Annoying!

I was thinking about it, but I was hoping to wait until it's officially released. Taking longer than I expected

Still happening in 5.6.890
I'm also suffering this very annoying problem, and have found no solution for it.
I'm using stock XT862 5.6.890 and I need to re-enable data roaming 20 times a day. I use a carrier in Spain that has very little owned towers so it's doing national roaming very often. Every time I switch from an owned tower to a roaming tower, I get the "Data roaming is disabled" notification and need to go to "Battery & data manager" -> "Data delivery" to re-enable it.
I have searched A LOT and tried all solutions I have seen, i.e. modifying build.prop in a myriad of ways, but it still happens.
I have also tried Minimoto v1.7 which has XT862 5.7.906 but it's even worse: It still happens but that ROM has stripped out Battery & data manager so I can't even enable Data roaming. A shame because the ROM is really awesome.
Please help a poor soul! :angel:

I finally took the problem in my own hands and managed to make a small app that re-enables data roaming at the touch of a button.
I needs to be installed as a system app for it to work, but it works! :laugh:

Data capability lost after signal loss

Every day I travel on the London Underground and obviously lose 4G signal when I am below ground.
Since the last update a week ago to 10.2.26.0, when I come back into a 4G area I cannot use any data services without either rebooting the phone or toggling Mobile data on and off, which is very frustrating.
The bars will show full 4G but no data will flow on any app until I do this.
Has anyone else experienced this?

Same on mine...

Yes same issue here

I had this happen to me earlier and it turned out that the access point settings had been altered at update from one firmware to the next. The system tries to install some generic APN-settings based on my operator’s name as my operator has no automatic way of installing them the usual way on this phone as it does on the more commonly used brands.
Check with your operator what the settings should look like and enter them under the access point settings for the sim-card if the current ones look off. Just an idea because I had the same problem going back to 4G from Wi-Fi. Reboot or airplane mode was the only thing to fix it for me. To be more exact it was the address for the setting “APN” that was wrong for me. The system had put an address that wasn´t a valid IP-address. Obviously, Xiaomi had tried to guess the address based on my operator name but got it wrong. As soon as I got the right setting in place all problems were gone.
This problem got worse as I had activated LTE voice calls. Before that it only happened occasionally, but with LTE-voice calls activated it happened every time I went from Wi-Fi to 4G.

Doesn't seem to be the issue. I am on EE here in the UK and the APN is correct. Can't see how toggling data off and on would resolve this if the APN was wrong anyway?

I can see that but still, do a trace route for apn.fastweb.it and it can´t solve that address so there is something wrong with it. Anyway hope you will find the culprit of your problem!

I almost have the same problem .. after a phone call 4g disappears .. After the talk 4g comes back but the data connection does not work anymore .. Data off and switching on is the solution. I have send my phone back to the retailer i hope dee can fix the probleem.

I have the same issue.......latest Global Beta......switching data off and on for now....and hoping that fix is coming as it is annoying...

Okay so this is found to be experienced by others - how do we bring this to Xiaomi attention? Right now a phone that just randomly chooses to lose data capability is useless, as I lose notifications, messages, home automation activity prompts, Ring doorbell alerts, Nest smoke alarm alerts - pretty much renders the phone useless if I am not connected to WiFi, and the worst is not knowing it's stopped working till I try something.

One thing you could do if you have activated VoLTE is to deactivate VoLTE. If this makes a difference it sugests that something is wrong in your local configuration. Otherwise you may have to take it back to the seller.

Same problem here in Germany with o2.
I just found this solution to slightly another but very similar problem and I'm testing it right now.
Go to the APN settings (Settings -> SIM card Settings) and better do a reset to default (not necessary). Choose the o2 option and in a field called MVNO type select IMSI. You should be fine.
Will report back if this worked.

VoLTE is not enabled on my device, but this doesn't sound likely anyway - I have had the phone since the first week it was available in Europe - over 3 months - but the data stopping working only happened with a recent update. Anyway, this thread and other forums suggest this is a wider issue - can't see that sending it back to the retailer will achieve much as the replacement will likely do the same!

The APN settings are all greyed out on EE - I can read them but I can't edit them?

Any news here? I'm still stuck with this annoying problem.
I'm on MIUI 10.2. 9.0 Global and no updates available.

Just came here to say I have he same problem. Not really too annoying as all it takes is toggling airplane mode off then back on after a couple of seconds. But sometimes I don't even know the problem has surfaced and I end up missing notifications.
It happens sometimes even after I enter an elevator then leave.
