[Q] Help! "Mobile network not available" - Captivate Q&A, Help & Troubleshooting

Help!
My phone is unable to connect to a network whatsoever - I can't make any calls, texts, or use data (only WiFi works).
I have a Captivate on Bell (phone from Rogers) which has been running great for 6 months. Last week I was setting up Widgetsoid (a power control widget) and changed the data toggle mode to Root Toggle. Since doing that, my phone disconnected from Bell, and has been unable to connect since then. I've tried everything I can think of for the past 4 days and have looked up the issue online, to no avail. I'm a noob!
I have tried:
-Hard Resetting
-Changing SIM cards: my wife's SIM has the same problem in my phone, and my SIM card works fine in her phone - thus my SIM is not the problem.
-Reinputting APN info
-Leaving battery out for one hour (one reported solution)
-Changing Network Mode from Auto to WCDMA only (another reported solution)
-Turning on & off flight mode several times (another reported solution)

Your help is extremely appreciated!!!!!

Once you have been extinguished from the flames you are about to encounter from posting this question in the development forum... I am sure a mod will move this to the correct section and someone will answer you.
Have a nice day. LOL

Why not ask in the S7 thread? Maybe because there hasn't been any progress on that rom since Christ was a cowboy?

4 days? Wow. Have you tried re-flashing the S7 zip? That or a "wipe data/factory restore" from CWM will fix it.

Check your IMEI by pressing *#06# ,
and check if the first 3 digits are null.
the same problem happens if the IMEI is corrupt..!!

Wrong section, anyways try another rom .

I've had same problem before on S7. Easy fix, check you system/app folder and see if stk.apk is in there. If not, you can take it from other ROMs and put it in system/app then reboot. You should be good to go. S7 dose not have this .apk by default. FYI, stk.app is sim card management app, it can actually send and receive info from/to your service provider. I might be wrong but that's how I fixed this problem.

The last time I had this problem (actually the last TWO times) I had it returned to AT&T return center for a "new" refurbished phone. Luckily the return center is slightly over a half hour away from my home.

yeah, i dont understand how its STILL in the dev section

I've actually noticed this too from time to time.
No idea exactly what causes it, but usually a flash to stock and a new ROM fixes it.
Usually it comes about after lots of network mode switching, or trying to force the phone to connect to a specific network.

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...

JP5 (i tried another one, don't remember what version but it's the same, it is not firmware related)
in settings->about phone->status it says:
network: 3 ITA
mobile network type: UMTS
service state: out of service
mobile network state: connected (and it works... )
but ... int the status bar it shows "Only emergency calls"...
i haven't tried another phone yet... will do now...

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.

My experience: first time install Lokout --> first crash!

Lookout uninstalled two weeks ago, no more crashes (instant reboot because system fault)
I don't say it is something wrong with Lookout, in my case went wrong!!
Yes, I have had a couple of random reboots while using the phone, don't know why.
Same issue. Reboots ~twice a day.
Checked logs - nothing interesting. Only once i saw there kernel panic backtrace, but unfortunately i've lost the trace.
It was somewhere in the wireless code, with pretty message "EAGAIN!"
Checked kernel sources, found the message in the wl_iw_iscan_get_scan function.
After i have provided that information to HTC support, the support told me to change my SIM card to newer one (i have SIM that made in 2004), and to set the field Network mode at Settings->Wireless and networks -> Mobile networks to the GSM only.
Changed settings. Waiting for reboots )

This is interesting.... does that mean we bought a 3G phone to run on 2G network?
if you have a decent provider, you can always ask them to send you a new one. Usually they will give u a new sim-card for free. Also add the message from HTC it will be more convincing

About time, someone highlight this auto-rebooting problem, im from singapore and i can tell u guys its a major problem amongst incredible s users here, 2 out 3 experience this on their incredible S. I can confirm its not apps that is causing it cause mine auto-rebooted fresh out of the box, and some users did a hard reset and still experience the problem. Apparently the first Htc incredible also face this random reboot issues. Im thinking possible hardware..

hmmm... I got the phone for almost 2 weeks... and the reboots took place at an interval of about 3-4 days
however, IIRC, 1 reboot took place before I went to bed, and it was in 2G...

Hi,
I'm an IS owner, the first one I had rebooted 3 times in 1 week.
I also had other problems with this phone and I decided to turn it back to get another one.
I tought it was just with the 1st but I encountered reboots with this one too.
I think it's a major problem with the IS, and I hope it's just software problem and then will be fixed with the GingerBread update, I hope so.

May be it's different problems. I have at least 2 reboots a day, and after moving to 2g - no any. Still testing.
Going on 3 weeks and my phone rebooted for the first time. Hopefully this doesn't become an ongoing problem. I came across another thread where people were talking about their phone rebooting a lot.
I will be visiting local HTC service centre later today.... and I would like to see what they have to say about this issue.
After all, I have done quite a fair bit of troubleshooting myself:
1. Change SD card (original 8G class 4 -> 8G class 6 -> 16G class 4 -> 4G class 4)
2. Factory resets (soft and hard)
3. Change of SIM (I have 2 lines )
If I can get anything today, I will update
Two days without reboots. Changed SIM and switch 3G on. Testing...
My sister has an inc S and she had now in about 4 weeks 5 reboots. 3 in the first week. I'm keeping an eye on it now to because she asked me for help, but I couldn't find out the problem. I think it could be firmware related. So I just hope GB will leak soon for the Inc S and maybe it will be fixed then.

[Q] N7000 3G Radio failing

I've had my GT-N7000 for about a year. It has been rooted and running various ROMs since I had it and has always worked wonderfully. I had settled on CM 10.1 about a month ago. Since the last 3-4 days I noticed that my 3G signal showed no bars from time to time. Normally, just a quick 'airplane mode' dip and everything would be fine.
2 days ago was still having the same problem and I had to completely turn off and on again to 'maybe' get a signal. If I got a signal, it would only stay there for a few minutes and then disappear.
I changed the SIM card yesterday just to be sure but I still had the same problem. The same SIM card works perfectly well in my GT-I9000 running CM 10.1 as well.
I cleaned the SIM slot contacts, verified the internal antenna wire and even flashed a few modems and still have short lived and intermittent 3G signal. Any idea about what could be happening? Could it be the 3G radio failing on me?
Thanks for any help.

Anyone?
Does this happen after you move from one area to another? For instance from work to home or Vice Versa?
same problem
Hi there,
I've got the same problem than you. I got my Note 1 year ago, and since few days, I've a problem with the SIM.
On boot or reboot, the SIM is perfectly recognized and works good. I can call without problem, and can connect to the wifi without problem. The problem is when I use 3g, the SIM is not recognize after 1-2 minutes. I mean, I can access internet, do whatever I want, for just a minute or two. After that, the signal drop instantly. I tried:
plane mode: doesn't come back to normal mode cause the phone says there no SIM card
change modem: don't resolve the problem on all XX*** modem for JellyBean
change ROM: I was on German-leaked 4.1.2 Stock ROM, i tried 4.1.2 Switzerland ROM (where I live), 4.1.2 custom ROM and cynogenmod 10.1 (4.2.2). Always the same problem.
Tonight I'll try another SIM in the phone, in the case that the SIM is the problem.
otherwise, I don't know what else to try...

Are you sure it is the radio causing the problem and not the antenna? I know on mine, the USB charge port can be a real PITA when it
goes bad, and I had to buy about 3 before I found one that worked properly. With the wrong one, the radio signal would fluctuate all
over the place, so that's why I wonder if it could be a bad antenna/connection/board problem, since it is contained on the same
board as the USB port?

I had an update..
I figured out that when i change the network mode to GSM ONLY it runs very well and never drops network signal or get the NO SIMCARD message..
but when i change the mode to AUTO or 3G/CDMA it drops network and gets NO SIM CARD after a few minutes !!
still don't know the reason & still searching
Let's talk about this problem. Mine is similar. Not getting errors with aim card but when i place or receive calls while in wcdma mode, conversation is normal at first place, then after few seconds i can not hear other side, and other side cannot hear me, sometimes that call ends and that is it. On gsm only, calls work normally, but internet is not working, while in wcdma internet works... pretty nasty issue. I tried flashing different roms, tried several modems to flash, problem is not disappearing, but from modem to modem i can see improvements. Sometimes it does not drop at all... can you help me with this?

[Q] N6 - No incoming & outgoing Calls, mobile data gone.

Having my Nexus 6 for almost a month. Things working perfectly in the starting(or after reset), but after two or three days, No incoming calls, no outgoing calls. No mobile data. Cant realy tell it as a mobile sometimes. Wifi is working good always. After reset, it is working properly for two or three days. Whenever it is not working, I am able to see a !-mark near the tower bar.
My mobile always connected to 4G when no wifi.
No Custom ROMS and no root. Plain Android given by google.
Anyone having this issue. Any suggestion?
Go get a new SIM.

I was begining to think i was the only one who had this problem!
Yesterday morning i woke up and to my suprise my signal bar had a (!) it it but it was still displaying my regual signal level.
I switched my wifi of and i couldnt get a data connection just the (!) sign. I got my girlfreind to give me a ring and see if a
call would go through which it didnt it just said that i was unavalible. I then desided that a reboot might sort the problem
but when i my phone booted back up i was presented with the holow triangle signal icon to say that i had to signal. I then
popped my simacard out thinking it could have just been a bit of dust on it. I gave it a little bit of a dust of and popped it back
into my phone and i was given the same no signal and emergency calls only yet it was picking up that there was a simcard inserted.
The day before i had flashed the alpha version of PA so my next thought was that this would be a ROM bug and went ahead and
flashed chroma which i was using prior to PA and i had had no issues with. Held my fingers crossed as it booted up but much to my
dismay i was greated with the same no signal problem but i went into the settings and searched for networks. Three was one of
the network it had picke dup so i tryed to reconnect to it but i got the toast to tell me i couldnt connectto the network and to
try again later. I checked the APN settings and it had automatically grabbed threes APN from the sim card so at this stage i was
completly baffled by them problem.
My next move was to try my sim in my girlfreinds phone and what do you know it worked a charm. As a last shot to check everything
was okay and i was upto date on my bills etc i gave three a ring and they told me there was nothing wrong with my sim and everything
was working as it should be and that it was a problem with my phone.
That brings me to the point i am at now completly baffled as to the problem and slightly angry at the 2 week old phone that had been working
perfectly up until now has suddnely desided to stop with no warning.
So you are not the only one and i expect their are more of us. I am going to flash the offical stock rom from google and see if that does the
trick but im not holding up much hope i feel like im going to have to contact google and find out where the problem lies.

I got this as new nano SIM from the retailer and seems like working in all other mobiles except Nexus 6. Also I can see lot of people having the same issue with Sprint Provided in US. One more Victim replied too.

i reverted back to complete stock using the image from there site to no luck so i relocked the bootloader and took it back to the carphonewarehouse and they straight swapped it for a new one which is working perfectly
My sim died after a month. My calling went out and then only lte worked no 3g. Got card replaced and it works perfect now. I have US Cellular.
I've posted this in few other threads also, but I had also problem where I only had tgt exclamation mark no matter what I did. I solved the problem by waiting like 5sec before inputting my pin-code. If I input my pin code too fast after a boot, it will open my phone, but won't give me cellural network. This seems to happen in every ROM I've tried
Hi,
Solved the issue. Working fine after enabling request for SIM Pin and set my sim pin.
Usually i disable sim pin lock to have uninterrupted boot. But with ROM this is not working.
Enabling SIM pin request solves the issue.
Is this problem with carrier or Android L?

I have not seen this issue on three devices I've owned with Lollipop. So it appears to be a carrier issue?

[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.

The thanks should go to @Circaflex though... he told me how to fix my issue and thought it could be useful here. I'm glad it was.

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.
