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.
meh

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!

anyone on ATT having data problems?

I've tried various different ROMs but it seems since installing the latest releases of Froyo I can't seem to get any kind of consistent data speeds any more.
One minute I'm getting 2mb the next I'm getting 200 or no connection at all. I've tried going back to other roms even 2.1 (cyanogen) but still have the issue. I don't know if it's network related or something is messed up on my phone.
I'm going to go back to completely stock everything (including radio) and see if I still have problems but just wanted to post here to see if anyone else has seen issues.
Thanks

Before you resort to messing with your device you might want to call AT&T and ask them whats up with you area. I found that 16 out of 20 towers in my arean were down and that was the problem. I continued to question them about what they were doing about it and found that the answer was nothing. The towers are Verizon owned and they cant do anything about it. They gave me a $280.19 credit on my account which almost pays next months bill.
I saved myself from the trouble and got next months bill paid.
Now, thats killing 2 birds with 1 stone

Yeah I've been having absolutely terrible data all day. I got on here looking for a thread about this. I'm also on AT&T. It has pretty much stopped working completely for the last two hours.
I read there was a nationwide outtage and people thought it was T-Mo but they claimed it was HTC.
Not real sure what the issue is but it's getting annoying.

ya... I ended up calling them... they said not having my IMEI # on my account would cause strange things eventually when the system does it's scans or whatever... they added the # to my account and data seems fine now... well, fine within ATT standards lol

I have been having big issues with the data connection since froyo came out.
Data will get "stuck" on sending and no program (browser, sync, market, ...) will be able to send or receive data ... they all time out or give a network connection error.

The did do an IMEI scan. They shut off my data because I had an iPhone plan.
I just hulked out at the ATT store for half an hour.
I'm still using a GSM carrier because I want to switch phones whenever I please.
They put me on the smartphone data plan. What happens if I want to grab an iPhone 4 and switch back and fourth?
So Angry. Don't Tread on Me!

Well I feel like an asshole. SwitchPro Widget disabled my data connection.
**** it I'm getting an iPhone.

anyways i always seem to have some issue with AT&T data. mostly 3G. i could be doing fine at one point and then a few minutes later, i cant load pages or do anything data wise and then im forced to turn the 3G off or connect to wifi if its around. $30/month for this crap?

If you look around, there's a broad array of AT&T data problems the last 2-3 days... So something is going on, and I highly doubt it has anything to do with any hardware, software, etc, except for specific examples of course.

Crock'o's###e (it's an Irish crock, so there's an "e" at the end). All they need is the SIM card #, or ICCID, to authenticate the user. The IMEI is irrelevant and if the network needs it, it's auto-pulled from the switch (GSM phones always broadcasts the IMEI when they connect, it's how they nab people for the data plans). What the rep is doing with the IMEI is just updating the billing system, not anything network related (again, since the network already has your info). Now...what happens is that whenever you change the SIM or IMEI in the billing system, it orders the network to push out an OTA SIM update. There is,however, an option to simply send the OTA without fudging with the numbers.

Oddly enough, I ran the "mark the spot" application and at the end, it asked me if I wanted to run a diagnostic test. I selected yes and then about 10 minutes later it sent me a free text message acknowledging that they received my issue.
Now i'm testing my speeds and everything seems back to normal!
I'm getting consistent 1.5 up and 1.5 down whereas I was getting < 100 each way a couple of hours ago.
I'm in MD btw.

Ya I've always been thinking the same thing but was rather desperate to get better results after a week of poor performance and, surprisingly, after updating the IMEI # I was getting full speeds again. It could be purely coincidental but I guess there's absolutely nothing wrong with having the correct IMEI on file.
ATT has been sucking lately. I don't know if it's the froyo radio or what but I have been experience a lot of lag when the phone has been off for a bit then trying to initiate a data connection. ATT's data network can be absolutely awesome or absolutely SUCK, depending on the time of day and network utilization. I think I'm ready to jump ship to sprint (apparently they've really cleaned up their network problems in central ohio) or verizon but the Nexus has me stuck to ATT until something significantly better comes a long to switch into.
Too bad all newer phones on other networks all have those craptastic sudo layers like sense and blur... that crap and the "personal touch" of the carrier to android releases always ends up in it being a small eternity before you actually get the latest android. This is why the Nexus stays in my hand... I sure hope someone else releases a vanilla android phone that's support as widely as the Nexus.

but yea i hope it has nothing to do with hardware. i was just fine with my nexus one using 3G up until a few days ago. i hope this is AT&T's way of fixing their 3G. this better get cleared up soon cuz im sooo ready to jump onto Verizon's Droid X or jump on T-Mobile's Galaxy S (while still being able to use my sim card on my nexus). i always had issues with AT&T and i just tried to ignore it while i was on the iPhone 3Gs/Nexus One but now this is ridiculous. i have had a few nights were i would get no data service at all. i was scared as sh*t thinking i messed something up while i was flashing (i happened to have flashed something the night i had no data) but when i woke up the next morning, i had data again. im almost fed up with AT&T. im paying $175 a month for two lines and this is the crap i get?

[SOLVED] Phone network issue

Hello everyone,
Informations
Phone : Nexus 6
ROM : Euphoria OS 1.0 with included kernel
I have a little problem with the phone network...
I have just install the ROM (3days ago) and everything worked fine.
After the first reboot, I had a network problem: no more network (just phone)
Bluetooth is OK,Wifi also ect...
No extra apps installed.
Any idea?
Thanks
Edit : French phone/network (FreeMobile)

I am having issues over here also. My data randomly stopped working on my way down to memphis, randomly would start to work again. I tried a new rom, it slightly got better, but would cut out of data every 5 min. Kinda got it better by switching to tmo in the apn's. Now just installed sinless, and it is no longer working again.

So, same problem and no fix...? :/

Holy cow! I thought I was the only one! I mean this problem really sucks(and I have wasted a lot of my hours trying to fix it), and have been thinking of creating a thread on this problem until I saw yours.
Okay let me start with what I'm on:
N6: 64gb blue
Rom: Stock
Rooted: Yes
Any other modification: No, only think I did was unlock and do chainfire su root.
Network: VZW
I have had this phone since Dec with no issues other than random reboot every so often.
Now to the problem I had, I went out to the middle of MO for a weekend get away (on Feb 14th). The whole time I was out there it showed 1x even though I was still getting LTE speed. Didn't think much of it until we moved further into the hilly parts of MO were I lost service. Thought it was just where we were at, and thought it would come back once we got back to the hotel we were staying at. It never did. It would say "No Network found" only allow 911 calls.
Spent the next 4 days working With VZW with several trips to the store, and talking to tech support. They made sure my IMEI was not blocked on their side. We used several sim chips, they would all do the same thing, quickly connect then disconnect and go back to no service.
So I did a factory reset, still didn't help. I finally did a fastboot flash of 5.0.1 stock again, this fixed the issue. Until I used titanium backup to restore my sys setting. Then it would drop and not reconnect after the reboot. So I did fastboot flash again and it hasn't happened again since last Thurs. I just restored my app's again to make sure it wouldn't fail to connect over the weekend, and rebooted several times. No issues so far, but I called Motorola and they are RMAing me a new one, because I don't have any trust in this one anymore. They are out of 64gb ones, and they will get back to me in a week.
Questioned to anyone who has gotten a RMA from Motorola:
Are their "like new" replacements okay? I got a few from them when I had my droid x, and they were crap. So I wasn't sure if that is still the same for the N6 or not. I have a feeling its not, but just wanted to get other peoples input on that process.
Thank you for creating this thread, and for everyone's time!
Edit: Had the same issue network wouldn't work, however WIFI, Location, Bluetooth would.

Check your APNs..... make sure you are on the correct one, and that both of APN protocols say IPv4.
Sent from my Nexus 6

APN is for Internet(3G) and MMS, no?
Because we have a phone network (call & SMS) issues.
On my side, APN are OK, but still don't work...
Edit: New !
Everything works fine on :
- Paranoid Android 5 Alpha 1
- Chroma (Latest)
But not work on :
- Euphoria
- Stock ROM
Edit 2 : It works now !!
I seen that I had several issues around the APN side. I mean, I can't add APN, sometime I can. Sometimes APN reseted themselves, sometimes it was OK. Then, I had read the solution above: security tab.
I had just remove my 3rd party lockscreen (HiLocker). Restart the phone and voilà ! After the reboot, my phone ask me the pin code, and all APN are here.
I hope it can help...!

Some times I will see the APN settings, and sometimes I won't. Right now I don't. When it does show up it shows VZWINTERNET selected. There are ton of other options, but they don't work either when the problem was seen.

Is what your experiencing data going in and out? I'm on Sprint and I thought maybe it was just an issue with Sprint. I have or need to read up more on APN because it does get bothersome. I even have issues where sometimes my SMS gets hung up for minutes in sending mode before they actually send. Would be nice to have this corrected.

No my whole problem was that it would drop and no matter what I would do wouldn't reconnect to the network. I tried a lot of things to fix it (see above). APN would appear and then disappear from the menu. Right now its working on the network as of last Thurs. and APN options is not there.

The APN option will not show for a CDMA Carrier, Sprint or VZW, in your case VZW. APNs are set by the Sim from Verizon so you shouldn't be messing with those, nor should the option show up under mobile network settings.

It was like you. Sometimes network was OK, and sometimes, it was down...

So current working theory is that it was a software issue that cause the problem. I'm just unclear as to why it happened, and how to stop it from occurring again . I do have OpenDNS enabled on the phone, could that cause the problem?

Heres my problem, I'll drop out of an LTE zone, and 3G/HSPA will come on line. Only if its on 3G I never get any data, and sometimes with HSPA too. Not until LTE comes back on line again, but then if I'm trying to stream say music 3G/HSPA wont let LTE take over again for a pretty long while.

Nexus 6 LTE connecting issues... strange!

My rooted Nexus 6 and my sons stock Nexus 6 are having a lot of trouble connecting to LTE on Tmobile. I have to go to APNs, reset to default and reboot every hour or so. I did no changes to my phone.
Apparently, this is happening on other networks too.
Can anyone shed light on this? Some back door google update.
tMobile says no changes on their end. Also, other carriers are having this issue, ONLY Nexus 6.
PS - apparently , this has happened before too

flash a different radio/modem.

Same here. Just spoke to T-MOBILE and rep said it is an issue with a lot Nexus 6 users. They kicked me off the network and it work for a bit but I'm still losing data. She said their tech department is working with Google for a fix.
Fyi...Flash 3 other radio's and it doesn't make a difference.
Edit: change all to a lot

I got the same answer.
I did flash the 5.32 and 5.34 modems. No dice.
Then I tried Developer preview 5.39. It's been working for 15 minutes, which is a long time since the issue cropped up.
What a pain!

Not sure if my issue is the same, but for the last couple days Textra fails to send a text unless I reboot. Even a reply to a just received text fails. I have tried a couple different radios but neither has helped. I am also on a T-Mobile Nexus 6 stock rooted with the August 6.0.1 security update.

That is probably the same issue. I can receive texts, but can't send without a reboot.
So far.. the 5.39 developer modem has kept connection for an hour. Which is good considering how intermittent it was.
What really blows is that my phone and service was perfect until this event.
Even in the mountains of the Philippines last year, my phone worked perfect.

You may try dp5 my WiFi and Mobil got a lot better, but I'm not on t mobil. Flashing only the radio is maybe not enough, if you are on stock anyway you have nothing to loose

Check out Reddit for the growing thread on this issue. Happening with Nexus 6 users on different carriers around the world. Some GPS connected apps like Pokemon Go & Lyft will bork LTE connectivity. Probably a Google play services issue. Will be using my OnePlus one today just in case.

Interesting.. I hit the speedtest app right after a reboot to check, and it immediately borked my connection several times in a row. I like your theory..

Not sure if my issue is the same, but for the last couple days Textra fails to send a text unless I reboot. Even a reply to a just received text fails. I have tried a couple different radios but neither has helped. I am also on a T-Mobile Nexus 6 stock rooted with the August 6.0.1 security update.

You guys have a lot of company... > http://www.androidpolice.com/2016/08/04/some-nexus-6-owners-report-data-outages-on-t-mobile/

I'm running stock N6, not rooted; bootloader locked; on T-Mo. While on WiFi, with WiFi calling enabled, I would get out of range of WiFi and cel data would not return without full reboot. If I disable WiFi calling before leaving WiFi service, cel data flipped as normal. I tested again with manual WiFi disable and if WiFi calling was on before the cut out, cel data never flipped on.
[Edit] I did notice though that when it does flip like it's supposed to, I'm connected at 3G. LTE doesn't kick on.

its NOT an issue with all n6 users on tmobile. i have a nexus 6, since nov 2014, and have never ever had that issue on tmobile. been on tmobile since the early 2000's..

Stated what T-Mobile told me.

Ok, I did flash the beta radio 5.39.
It might be coincidence, but my phone has a solid connection for three hours now.
Hopefully they fixed it on their end.

I am not seeing this on my N6. Still on 5.1.1 LVY48H.

what radio can work on 5.1
Cause i have flyme rom, but have calls issue, ian not receiving any call. The other end saids it rings but my phone does not ring at all on calls.

It seems to be affecting some people, but not others. It also doesn't seem to be related to ROM, carrier, kernel, or radio versions. There are people all over the world on different carriers having the problem.
The symptoms I see are that I can't connect to any type of cellular data. Voice and SMS seem to work though. WiFi data works fine. GPS use seems to make it more likely to fail. Speedtest.net, Pokemon Go, Ingress, and Google Maps have been used to reproduce it.
The only thing I've found that seems to help is to freeze "Google Connectivity Services" using Titanium Backup. You might also try uninstalling updates, though it will just re-install. If it is related to that, it would make sense as the rollout of updates via Play Store are staged, so people would get the update at different times. I froze it about 4 hours ago and data has been solid with GPS use, LTE and HSPA tested. I also tested switching between WiFi and Cellular without issues on Tmobile-US. That's the only SIM I have, so I can't test other services. I couldn't seem to get a data connection for more than a few minutes before, so it's a huge improvement in my case.

T-Mobile acknowledges the issue. The one universal is that it's with the N6, not with other phones. There are a bunch of carriers around the world that are having the problem.
When mine breaks, SMS fails. The only mobile connectivity available to me is phone calls.
The Reddit thread mentioned above has people saying that disabling Location Services works. Far from ideal over time, but if it's true, it's something. I tried that. We'll see how it goes. Freezing Google Connectivity Services is nice, if it works without introducing other problems, because it would allow us to keep using whatever connectivity we like without data breaking.
I had a Bluetooth connectivity problem a year or more ago that surfaced literally out of nowhere and on every device I tested, a little more than ten of them. This was independent of ROM, root status, device, anything. The feature in question worked on every Android device we had tried one day (and for more than a year prior) and failed on every one the next. Sounds crazy, but it's what happened. Google barely paid attention to my bug reports and ran me in circles when they did. Never got fixed.
I trust this matter will.

Both my nexus6s are doing this with heavy GPS aps, data will shut down.

I've had GCS frozen for a long time, running 5.39 radio & it happened to me. There is definitely something occurring substantially with our devices/network be it software or hardware based. Apparently T-Mobile & Google are working on it but the fix might not come until next week. I'll probably install latest N preview when I get home.

Nexus 6, T-Mobile and MMS problem

This has been a frustrating issue. My wife and I both have Nexus 6 phones. She has the 32gb & I have the 64gb version. Hers recently started not receiving MMS messages. Anything with a large picture would simply never show up. Anything with a very small graphic or group text would show up as "Non-text content". Here are the steps we've taken to solve this:
1. TMO started by insisting it was an APN issue. So she edited her APN. Didn't help.
2. We then swapped SIMs. Hmmmm. My phone then behaved like hers while hers could then send/receive MMS.
3. TMO said ok maybe it's the SIM. They sent us a new one. SAME result. Her phone wouldn't receive MMS.
4. Out of frustration, I factory reset her phone and reset the APN info. Didn't help. (Cleaned up her phone of some trash programs though. :laugh
5. TMO engineering says they still can't find anything on their end. Elevate to tech supervisor. She tells us to go a TMO store (right near us) to try a THIRD SIM. OK, we do. SAME RESULT. We tried swapping SIMs around again and the same thing happens. My SIM in her phone, everything works. Her SIM in mine, I can't receive MMS.
6. TMO store guy suggests MAYBE (but unlikely) that there is something her account has that's stored on the SIM when its activated that causes the phone to freak. Also says it's above his pay grade .
So now we are again waiting on TMO to poke around further on their end. My question for all you smart types here is:
Has anyone ever heard of this issue? Is there anything you know of that could be causing it? I think it's a bad provisioning somewhere in the dark recesses of TMO. The ONLY change we made to our plans (which seems just coincidental) is that we moved from the 2 lines Unlimited for $100 plan to the over-55 Unlimited plan. We did this maybe 3 weeks ago. But the features are all the same on both plans.
We are both on the same Android 7.0 final OTA firmware updates from Google. NBD92G
Would there be ANY chance that a sideload firmware update would make any difference? We're getting desperate here. Any & all suggestions welcome.

I wonder if her SIM is configured for wifi calling. There has been a conflict between wifi calling and mms for awhile. I've seen it reported several times where this T-Mobile forum post helps in that case

Don't use old firmware... I had issues on certain custom ROMs and old firmware where MMS wouldn't work over WiFi. Never as bad as you were getting.
If you wanna stay stock, sideload the latest OTA to go to NGI55D. Anything older than that is vulnerable to Blueborne exploit, which is a HUGE security concern IMO. I can confirm MMS is working correctly (even with WiFi enabled) on bone stock NGI55D as well as custom ROM Dirty Unicorns v11.7.1 which includes September security patch.

I've had this issue on most LOS roms. i ended up making a custom APN i flash when i try a rom built on LOS.

Yeah, it sure sounds like a problem with account partitioning, or something else with the account that gets associated with the SIM on initial use. What if you try the problem SIM in a phone that is not a Nexus 6? I wonder if you could get a new sim and set it up in a different phone, then transfer it to the problem phone?

OK all, finally got a TMO engineer who agreed with my assessment -- that it was a hidden provisioning problem. She nuked my wife's line and recreated it from scratch. Everything works great now. Frustrating that we had to go through about 15 phone calls and over 3 hours of phone time to get it resolved.

Glad they figured this out.
