Phone won't connect to network. - Samsung Galaxy Nexus

Hi I have a GSM Galaxy Nexus and today I simply stopped receiving signal on it. I don't know how or why. I didn't flash anything or even use my phone at all. At one point it was working fine, then I noticed that where my signal bars should be, I have nothing but greyed out bars and an "X" on top of that. This was hours ago. I called T-Mobile(I use T-Mobile Prepay) and they had me do several things like remove battery and sim, and nothing helped. I have a custom ROM(Black Bean). I have used this ROM for weeks with no issue. Just to make sure I did a nandroid and I restored my old Stock-Rooted ROM. Still no signal. I then did a full wipe did a full wipe and installed Black Bean 3.1.2(older version which I know for a fact works fine) on a clean install. Still there is no signal. If I try to make a call, it tells me to turn off Airplane mode before making a call. But I am 100% that Airplane mode isn't on. I can go and turn it on, then back off even. Still I have no signal. I have no way of knowing if this is my phone or T-Mobile having tower problems. I called but they don't know anything since it was the pre-pay support line call center in India.
I have been generally disappointed with T-mobiles service. I would gladly give up the rest of my current month and re-subscribe to Straight Talk with ATTs Towers right now, but I'd have to get service going with them again and that would cost 45 bucks. And it's a waste if there is something wrong with my phone. So now I don't know what to do! =/
Edit: Quick update, I put in my Straight Talk SIM thinking that even if it were out of minutes, it would at least let me connect to the towers so that I can add more. Still nothing. If I hold down power(under stock) it brings up the power screen and that tells me that Airplane Mode is on even though I have it off in settings. If i click on that message, it says "Airplane Mode is OFF" but it isn't really, because if I go out and back in again, it's back to saying that it's on. However, I do have it turned off in my settings. I will also mention that WIFI does work.

Check if you activated the 2G option under Mobile settings. I had a similar issue a few weeks back. Almost drove me mad.

Sounds like your phone is the problem if there's discrepancies about whether airplane mode is on.

A few questions about the GNex - Network, Mail etc.,

Hi Guys,
So, I've been using the GNex for about a month. I moved to this phone from a Moto Atrix and here is what I have noticed and have looked around but didn't see any good answers to these questions I am having. Hopefully I get some answers here.
Device info:
GNex GSM version on ATT.
Running JB 4.1.1 Stock with Trinity Kernel (rooted and bootloader unlocked).
Issue #1: I get really bad reception at work. But, when I leave the building, my phone doesn't automaticaly connect back to the network. Sometimes, if I don't check my phone, it's been like that all night long until the next day when I have tried to make a call and it said "No Network Available" and I have to either reboot or toggle airplane mode to get back on the network. Am I missing something? In my past experience with other devices, they try to automatically connect back to the network when they loose connectivity. Also, if I get in an elevator during a call and the call gets dropped due to network unavailability, it doesn't connect back to the network and I have to toggle airplane mode. Has anyone else had this issue?
Issue#2: This is with the stock mail app. Specifically the search in this mail app. No matter what, it always returns zero results. Has anyone had this issue with the Mail App? If I use the Gmail app, it works fine. That's what I am using now, but am curious as to what I may be missing that make it not return any search results in the stock mail app.
Q3: Speed Dial: How do you set speed dial on the dialer? Is it even supported?
thanks in advance,
vG

it could be to do with your radio, what version is it? baseband version in about phone. im no expert but when i flashed a jellybean rom i had to update my radio afterwards cause my signal was dropping alot. i also had the same problem later on but that was down to my network operator. before i realised it was them i googled my problem and a few forums suggested that my sim card was goosed. so maybe check those three possibilities? i cant help with the other two issues unfortunately but good luck sorting it out!

LTE driving me insane, lose it after switching to airplane mode.

Hello, I am on a rooted stock Jelly Bean Telus ROM with default recovery (I flashed the rooted stock image through ODIN). Every now and then I will lose LTE even though I am in an LTE area. I try to do the trick of turning on airplane mode and turning it off to get the connection to reset. This actually doesn't do anything. HOWEVER, if I restart the phone, I get LTE back with 20 seconds. Once it restarts it can stay on LTE for a long time. Even when I get a call it'll go to 4G and then switch to LTE once I finish.
But here's the kicker. If after I restart it, get LTE, THEN switch to airplane mode and switch back, it will never, ever connect to LTE again. I have to restart the phone to get it back. I've just done a hard reset and the same problem occurs. This sounds completely ridiculous and I've tried everything. Has anyone heard of anything as absurd as this?

Had the exact same problem with a Telus rom, I dont suppose you're on ATT by any chance?. Mine wouldn't connect to the mobile data network when coming off a wifi connection and would just hang in limbo until i switch mobile data on and off. Dumped it and went to a ATT based rom, problem solved. One thing I noticed is that the APN options with the telus rom are different than ATT roms, the apn type in particular
Ask in Q&A or the sticky thread for LTE
Thanks

Not connected to Mobile Network after being on Wifi?

This has been a frustrating issue I've been having pretty much since starting up my T-mobile service about a month ago.
To start off, my G3 is unrooted and on the latest stock software version, 20e.
I use Wifi calling often because I get 0-1 bars of reception at work. All seems to work well until I go outside and try to make a phonecall over the voice network. I'll have plenty of signal bars, be connected to 4G even, yet when I try to use the phone dialer to make a call it will say "Not connected to Mobile Network." or something along those lines.
I haven't done extensive testing, but I believe the other day I toggled the "Mobile Data" off then back on and was able to make calls.
Has anyone else had this trouble? Is it something possibly to do with Wifi and/or Wifi calling?
I believe I could make a phonecall using Hangouts when I was off of wifi, which tells me that the data part is working, but not the voice network.
I contacted T-mobile support, but they just had me do the "typical" things, like shut down the phone, remove the battery/SIM, start everything back up. And sure enough, it worked after that, but I'd rather not have to restart my phone or toggle stuff to get it to work as it should without any hassle.
Thanks!
My wife has the same problem after the 20E update. Her mobile is stock as well. It did not happen on 20B.

Off the top of my head no. I'll dig around a bit and see what if anything I come up with.,
From the digging I did I can't seem to find any help. The only thing I can think of is to factory reset it thing and see if it helps. I am going to do do it on my wifes phone tonight.
Yeah, that's what I was thinking too... I'm not really in the mood to deal with restoring all of my apps and whatnot, so I'll hold off on the factory reset for now.
If you remember, could you let me know the results? If I know for fair certainty that a wipe will fix the issue, I might do it.
Thanks!
It's a network problem and it is worst on Samsung phones. I recently went and got a new sim card and it seems to have fixed it. I read it is because if you live in a area where there is poor coverage it causes your sim to where out fast.

This started happening before my first month of T-mobile service was even up with a brand new SIM. I'm not saying that it's definitely not a SIM issue, just would seem unlikely that it's worn out that fast.
Mobile out of Network-Tmobile - Android
I;m having the same issue, turned phone off and on, checked Network connections everything looks fine, but now able to receive and send texts or make calls.

Network connection drops and squeeze for assistant stops working

Just checking to see if I am the only one having these issues.
I have the 3 XL on ATT, and I randomly have no internet access over mobile data, even though the notification shows LTE and decent signal strength. Screenshots attached to show what I'm talking about. This has happened about 4 or 5 times since I received the phone a few weeks ago. I went to ATT and got a brand new sim, thinking that my old sim may have been going bad, but that did nothing. Only way to get the mobile network connection working again is to reboot the phone.
I have also noticed a few times that the squeeze for google assistant feature will stop working, and I have to reboot the phone to get it working again. Anyone suggestions? I am leaning towards just doing a factory reset this weekend, but I would like to avoid that if possible.
Thanks
dont know about the edge squeeze assisit not working (i use edge sense module and app) but i have to reboot or go into airplane mode to get data to work when i get the x. maybe using a different apn would help... im on att too
AT&T issues
This is now a problem for me. I have to put my phone in airplane and then back to lte at least once a day in order to get mobile data working again. I'm not really sure if it's a network issue or a phone issue.
Issue for me here too, but I'm in Australia on Telstra network.

Question Phone Suddenly on Emergency Calls Only Until I Restarted It

When I woke up today, I saw that my phone was on No Service and it wasn't just flipping between full bars and no service for a second like it too often does (including dropping calls a couple of times). I tried to fix it by turning Airplane Mode on and back off, but it did nothing. I went to try to manually choose a tower to connect to mostly to see if the T-mobile tower near me was working or not, and there instead of a tower name it said "Emergency Calls Only". It did let me pick from the list and a disappearing pop-up said it connected, but it never changed to signal and stayed on Emergency Calls Only. So, I restarted my phone. Once it was back on, I had signal, but strangely I also got a Gmail notification about an e-mail that had arrived an hour prior, so I guess even my WiFi wasn't working! Bluetooth did connect fine to my Apollo Neuro anti-anxiety device, but the app was messed up showing it at 100% strength on two different settings instead of the strength they were saved at (and were sent to the device at), which was weird. Everything was fixed after the phone restart.
Anyone else had this happen? The signal issues on this phone are really starting to annoy me! Flipping to no service for a second too often, not connecting manually to any other tower (my plan includes unlimited roaming for talk and data) [I'm not sure if auto roaming works since I haven't been where it would be needed], dropping a couple of calls, not sending texts at times, Chat texting dots turning off often (usually fixed by going into Airplane Mode and back), and now this! I love the phone, but they need to fix it whether it is Samsung or T-mobile!
i thought i was the only one. suddenly no service to any calls but data intact. only way to fix is by cycle flight mode.

That sucks. They really need to fix this basic function of this phone!
I've had that issue when getting in areas where coverage is spotty, but never been able to see it go into Roaming..........just "emergency calls only".

It seems that is the issue, that the phone won't roam. That is a mega problem.
My phone was just sitting on the wireless charger all night, and I get full bars (occasionally minus one) here at home, so .
