Bizarre 'Mobile Network Not Available' - Nexus S Q&A, Help & Troubleshooting

Hello all,
The problem phone is my girlfriend's Nexus S (9020a) with the following details:
ROM: Slim_ICS_4.0.4
Radio: NO DGSXXKB1
Kernel: [email protected] #3
Her phone cannot connect to a mobile network. I've tried rebooting, I've tried cycling with airplane mode, I've tried reflashing the ROM, changing the Radio, changing the Kernel. Nothing worked - still no connection.
My phone is another Nexus S. I was under the impression that connecting with the provider was controlled by the SIM card, so to verify that her SIM card worked, I popped it into my phone. It works like a charm. This led me to believe that it was her hardware, so I popped in my working SIM card into her phone, and it works too! In fact, from her nexus S (with my sim card in it), I can call my handset (with her sim card in it), and the call goes through.
I think this rules out her sim card being faulty, as well as her hardware, and considering I've tried changing roms, radios and kernels, I think the software isn't the problem either but I can't be sure.
Her IMEI number matches the number under the battery, and I've double checked that the APN is correctly set up for her phone.
Any thoughts?
Thank you.
Werm.

Read the radio guide in development there's a part about getting your 3g connection back. This happens to my gfs phone once and it was a pain to figure out. But I believe the phone is not connecting to the right service I.e. gsm.

iu suggest you get a new sim card for your gf, since your card worked and hers didn't. it didn't cost me anything.

G2X won't recognize SIM card

Anyone else experience issues with swapping their SIM from their old phone into the G2X? I have reseated mine from my N1 into the phone 3 times, and each time I boot it says I have no SIM card. Pulling my hair out!
I went from an N1 to the g2x and i had the same problem so here is the deal...
the g2x is a 4g phone and it required a new sim card version so i had to trade in the sim card that i have had since my i got my razr in 2005...
so disclaimer to anyone who buys the phone outright, you have to have an updated sim card... just go into tmobile and they will give you one...
mines wont check for sim card at all it keep saying no service even without a sim card it usually say no sim but it just say no service can someone help plz plz plz
Fyi make sure it is a corporate store. Otherwise it could cost ya $20. Customer care might even be able to mail you one...not sure. If your near Chicago I would just give you one of my extras.

I reused the sim from my N1 and have had no issues but it was probably a newer version sim since I just got it beginning of last year.
If you have an old T-Mobile phone lying around, try inserting your SIM into that, and using it, then re-insert it into your G2X.
Alright I opened it up and it looked like the antenna cable was a bit frayed near the tip, I attached a few pics. It was connected though so not sure :/

I have the same issue.
Mint condition G2X does not detect my sim card reads "error while trying to connect to network"
I am running CM 7.2 I have wiped everything and reflashed still no luck.
Add one more to the pile...
I also recently began having this problem, but my device previously worked fine.
I have tried Restoring to Factory V21Y with Mar 11 Baseband
Flasing a GB Based ROM & Stock Kernel
Flashing CM9
Flashing CM10
Entering *#*#INFO#*#* Phone Info and modifying frequency band (No Go).
At one point I was able to read the Phone # from the SIM card, but couldn't get a lock on Netowkr. I can visually detect T-Mobile and ATT in Mobile Networks.
I have tried this with 4G Enabled SIM Cards and older T-Mobile SIM Cards.
I have tried Simple Mobile, Straight Talk, & ATT SIM Cards.
I have tried using None APN's, the TMo/Simple Default APN's, and Modified APN's for Straight Talk & Family Talk.
No avail.
Any ideas?
I had the same problem. A new SIM card fixed it.

I gave my friend my old G2x because she was switching from AT&T to TMobile. She went to the TMobile store and got a new SIM card and her old AT&T number transferred to it. It works on her old iPhone but when I insert the SIM card on the LG G2x , it keeps saying 'no SIM card inserted'....do i need to flash a certain baseband on it and/or setup a custom APN for it? I am on the stock ROM thats rooted...
Any help is much appreciateed
Sorry for not replying until now but I rarely visit here anymore. My G2X had a bad Sim card which a new Sim fixed. I just had to wait until the network could authorize with it.

[Q] Nexus s i9290a mobile network unavailable

Hey everyone,
So here's my problem. I have acquired from a friend, a Nexus S since I grew bored of my blackberry. Its running ICS 4.1.1. I am trying to set the phone up to work with my old sim card, but when I try to make a call it says mobile network unavailable.
I've gone through the APN settings for Virgin Mobile, tried to search for networks and it always comes up blank.
I've reseated the sim card, had the battery out for half an hour, left the sim card in for a couple hours (various tips from searching on the net for this issue)
The sim card works in the blackberry still. It connects fine to my wifi network.
I've checked the IMEI numbers, baseband numbers etc. So far nothing seems to work. I'm going to see if the cell phone booth guys can help while at work but figured asking here was worth a shot too.
I haven't tried any rom flashing or whatnot, since I've never done this with any phone previous. And most of the issues i've found on here seem to be similar to what i found on the net so far.
Thanks for any help

Telus Network Connection Problem

Hi, I just purchased the One S from a guy using Fido network and had it unlocked through cellularunlock website. I bought a new sim card from Telus and when I try to activate it the connection keeps dropping. It will work fine for about 30 seconds, if I'm lucky, then it loses connection all together. I tried all kinds of Telus apn settings and still no go. Thought it might be the sim card so I tried another sim card and still no good. I thought the apn would reset if I flash a new rom so I did and still drops, connects, drops and connects. Can anyone help me out? It's an S4 variation by the way

Stock JB Update Hosed up my radios?

I was blissfully working just fine on my MZ602 Xoom. I would pop the Micro SIM card out of my phone and into an adapter whenever I wanted to use the Xoom. It worked flawlessly.... that is, until I updated to JellyBean. Now the Xoom will not even SEE a SIM card.
I went to Verizon store today and the guy was about as helpful as diving gear in the sahara. He said you should not be able to pop a phone SIM into a tablet and it works... well that's BS cause I've been doing it for almost 2 years. "Well, then the update must have fixed a bug that allowed you to do that"... no duh sherlock... pop a SIM in from your repository and make sure the things even works still and I'll buy a tablet package. Well, he did and it did the same thing, no connection. "Not under warranty so, sorry man". Thanks for nothing, no I don't want a new tablet!
[/Rant]
I have since flashed the ICS radios and have the same issue. I have tried stock, non stock, rooted, non-rooted, Honeycomb with ICS radios, JellyBean radios.... nothign works, it no longer sees a SIM.
Previously when I popped in a SIM it would take a minute or two and then see signal, sometimes requiring a reboot, now it doesn't even recognize that a SIM was inserted. Before even if it wasn't picking up signal and I removed the SIM it would give a warning "SIM removed, reboot?" or somethign like that.
Currently running CM10.1 with the IMM76I radios. Works on WiFi but will not see any SIM card... am I hosed? Any help?!
Anyone?
How about this... Does anyone here still use their 4G Xoom on the Verizon network?
I plan to steal sim card from my wife ipad and try if I can find my sim adaptor. Will let you know.
I can tell you that my xoom no longer shows 4g network but always did before the update even though the sim card wasn't activated.

Did you use Rogue recovery to flash the radios? TWRP and regular CWM don't flash the radios properly.

Yes, used Rogue to manually flash ICS radios to no avail.
Previous load was 100% stock, unrooted on OEM bootloader and using stock recovery so the JB updated radios original flash was done properly.
I tried the Sim card from wife's iPad and it seemed to work OK. Although it seemed to connect a lot more to the 3g network than LTE and I have very song LTE signal. Radio doesn't seem quite as good as Previous.

SIM Detected But No Service???

Hey Everyone. So I just received my unlocked 7 Pro from OnePlus' website, and trying to use it on T-Mobile. Took my SIM card out of my Pixel 2 XL and popped it in. Noticed when I first powered on at the beginning of setup, there is no cellular signal. Went through setup and still no signal. Even updated to 9.5.13.GM21AA and STILL no signal. It's weird because it detects the SIM card in slot 1, and even shows my phone number on the SIM, but shows Network as "Unknown" and "Disconnected, Radio Off, etc." Same exact thing on SIM slot 2. The correct APN is selected and everything. SIM still works perfectly fine in my 2 XL. Even tried a friend's T-Mobile SIM card, and the same thing. It detects the number, but no signal. Did I get a lemon? Don't think it's the SIM since I tried two different ones, and my current one still works in my 2 XL.
TL;DR
Cellular network not working even though it detects the SIM card. Does this sound like a hardware issue? Already got a RMA number to send it back, but if it's a simple fix, I'd rather do that instead of having to ship it out and wait a week to get a replacement.
Any help is much appreciated. Thanks in advance!
have you registered to network or dialed *#*#4636#*#* are you rooted or no different options to take the project fi - t apn makes my whole network setting disappear lol i fixed it google dont play nice
i have the same issue now with my 7Pro, did you manage to get it fixed?
