Hey Guys,
I need some help with my G2x. Everything was working absolutely fine with it. I updated, modified the phone etc everything working great. One night, I'm sitting here and I pick up my phone to use it. I notice it says invalid sim card and I have no signal. I figured either T-Mobile had a problem or maybe I just needed to hard reboot. I did that, nothing. It finds the network for t-mobile, but it can not connect. No matter what I do, INVALID SIM CARD. I restore it, INVALID SIM CARD, NVFLASH restore to factory, INVALID SIM CARD. It was working completely fine and then one night it just crapped out and it's been over a month. I can't figure out what to do. I went to a t-mobile dealer today and got a new SIM card, it says the same thing! INVALID SIM INVALID SIM INVALID SIM.
I don't really know what to do at this point, I've tried everything.
I searched all over the forum, heard suggestions from call t-mobile to restore etc but nothing is working here.
My last ditch effort is to try unlocking the phone. I'm waiting for the unlock code now, but I'm really hoping that someone with more experience might know what I'm dealing with here and hopefully lend a helping hand in terms of some advice.
It'd be greatly appreciated. I'm fairly saavy when it comes to recovering bricked phones, etc. but I've never had an APN issue where the APN is good to go and the SIM works in other phones, etc. but not mine including when a t-mobile dealer actually links a brand new sim to the phone and it still isn't working, etc. No clue what's going on but I'm hoping unlocking the phone will help. Any help would be really appreciated.
Sorry to hear that happened. Did u try a different sim?

yes no sim card is currently working on it.
I just unlocked the phone, it does not fix the problem.
It continues to say invalid sim card. :-(

In the settings menu when I go to APN's it has the t-mobile apn and everything is correct. I go to network operators and ATT, T-MOBILE US and T-MOBILE GSM come up, but when I try to connect to any one of the three it says "unable to connect to this network at this time. Please try again later" I am mystified. I've tried everything I can think of.

Another point to make.
When I put in the sim card, even though it's NOT registering to the network and every card says INVALID SIM CARD, I received a notification telling me that I had a voicemail......... when I put my sim card into another phone and called my vm, I did indeed have a v/m.... so I don't believe the phone is shot, I believe something is just very wrong and I don't understand what it is.
You need a new similar, this happened to me, I rooted my g2x and it said invalid similar, if u show T-Mobile they will give u a free one

have you tried a full wipe then flashing a new rom?
simple method to try
Multiple times.
I've NVFlash recovered to stock.
I've flashed multiple different roms.
I'm wiped everything over and over, hard rebooted many times over.
Completely formatted the phone and recovered, etc.
I've tried a million things.
When I put the card in, T-mobile comes up for a second then goes away and says invalid sim card. I went to a t-mobile dealer, they gave me another sim card and it's the same thing. I really just don't know what to do. I feel like I've tried everything.
Do you have another T-Mobile phone, or any unlocked GSM phone, you can use to test the sim card? At least that way you can determine if the problem is with your phone or the actual sim card.
Sounds like an issue with your phone, but its always good to be sure.

if thats the case, then whats your warranty status?
they can replace the phone for you if the SIM card slot is defective
Unroot make , update to 2.3 if u haven't already and re root

Sounds like your baseband code got corrupted or your baseband chip went bad. Restore it and do a warranty swap if you can. No way to reflash baseband at this time on the G2X.

he might still be able to re flash the baseband via this method, especially if he still has the old one http://forum.xda-developers.com/showthread.php?t=1180331

Yes, if that works it will flash the new baseband and return his phone to GB stock. Worth a try.
hey guys... no warranty. It's fix it or I'm screwed, unfortunately.
It sounds like you guys identified the problem with the baseband corruption..
I'm going to try and do all methods suggested in the thread including unrooting and updating to gingerbread, rerooting... and also flashing the baseband...
I'll be back with some results!
Thanks for all of the suggestions, I'm obviously hoping I can resolve this!
Thanks again
I got "invalid sim" only when trying to start wifi calling and booting to CWM and wiping the cache and rebooting solved the problem.
If nothing works for you get a new sim card from t-mobile.
T-Mobile also had some funny setting in my account and after several hours with tech support and providing a sim card (phone number) of friend of mine they fixed it. As in ..my phone worked fine with my friends sim card but not with mine.
[HELP] I am having the same issue. I have a T-Mobile G2x/P999. I have had at least 10 roms without issues on the device. I flashed to CM7.0.1.0 stable and bam I have an Invalid sim card, I have tried to unroot, stock flash, NVFlash to stock, trying a different rom altogether with no avail. I have tried NV BAT Flash with NVFLash and nothing. I have found many post about CM7 after of course I flashed mine. My previous sim was new in April of this year, but I went to T-Mo and get a new one today with nothing. I to have wiped, licked, and spanked my phone with no results... CAN ANYONE HELP?? Can't even send it back in because I cant unroot it... HELP!!!!!

Yikes! Thats taking phone sex to a whole new level ... Did you try removing the battery and sim card, waiting a few seconds and then reinserting and rebooting?
Sent from my LG-P999 using XDA App
Yes I have done everything possible... Before the CM7.0.1.0 rom was installed, my baseband was from March 2001, now it reads July 2011. I have tried to switch back to the prevoius Baseband, but it wont let me either.
I went back to original stock rom because one of my co workers wanted to buy my Infuse to give to his wife. He did not want it to be rooted or have anything on it. I followed the directions in GTG's_Ultimate_Unbrick thread and it worked perfectly. Everything was completely stock like I just opened the box except for one thing...the sim card is not recognized. It says " NO SIM CARD IN PHONE AFTER YOU INSERT THE CARD, PLEASE REBOOT. EMERGENCY CALLS CAN BE USED."
I work for ATT so I know its not because the sim card is bad (I think I tried five new ones today trying to get it to work) plus I used working sim cards from working devices but it still says the same thing.
I tried running through GTG's_Ultimate_Unbrick again but to no prevail. Has any one encountered this or can any one please point me in the right direction on how to fix this issue?
Thank you in advance!!!

Did you wipe data/factory reset after unbricking?
If not, try that.
Today around 4:00pm I just had the same problem; however, the problem didn't arise when I used GTG's Ultimate Unbrick... The problem arose when I tried sending an MMS, I sent the first one, it worked, then I had to resend the same MMS to another person, it never sent it, so I tried restarting my phone, and that's when it popped up as "Sim Card Not Found" Ugh!!.. I just tried Flashing it back to stock using Odin GTG's Ultimate Unbrick. I was hoping it was just an ICS random bug, or maybe a just a ROM specific bug. So any help at all would be awesome.
Anyone have any ideas?

Make sure that the back door (SD card and sim) is ok. Many times when the back door is pulled the phone won't recognize the sim card.
it seems intact, the sd card slot works fine. and my sim card works on my other tmobile phone. also another issue, my device is always running on safemode, i have tried installing other roms and also reverted back to stock but it is constantly running on safe mode. is there a way i could revert back to complete factory origninal settings and start a new clean root process?

Try using Gene Pole's method to return to stock...
http://forum.xda-developers.com/showthread.php?t=1208507
See if that is working. The other way is using the Hack Kit to revert to Stock and S-ON...then you can start from scratch...
I did some research and didn't find a problem similar to mine.
I have a Samsung Galaxy SII Skyrocket that's 1 year, 1 week old today (so out of the warranty period).
I rooted it, have nova launcher, cwrm, and am running stock ICS on AT&T.
Earlier today, I noticed that I no longer had service which then went to No sim card inserted. I thought maybe it had gotten dislodged but that was not the case. I tried a factory reset and then a restore using crrm to a earlier date and still the same error. Even after the factory reset it had no sim card as the error.
My next step was okay my sim card is corrupt or something. Went to the AT&T store and got a brand new one and it still had the same error. this led me to believe it might be a hardware problem. I think I ruled out the kernel and the modem not communicating correctly because i'm not running any roms (nor have I ever on this phone) as well as tried to factory wipe and tried to put a fresh ICS stock via kies.
Any ideas as to why my phone still says no sim card? the sim card works as i'm using my old LGcu920 at the time of writing this with no problems. thanks in advance for any help.
flash my efs fix and then use Odin to restore GB. Reboot twice and then use Odin to flash ICS.

Before you flash that you might wanna try this. Take out your battery. Wait five minutes. Hold the power key(with the battery out) for 20 or 30 seconds. Then reboot. I've never seen anyone try this on the Rocket but I have seen it work on other phones.
hello
I have just got my galaxy tab2 10.1
android 4.0.3
first I worked on WiFi as well, I insert my SIM and reboot and I lost my WiFi connection the WiFi is working but can not find my net signal,also I tried different SIMs ,also removed the SIM,the problem can only solve by factory reset ,any other way to fix ??
thanks
any suggest?
sounds like your best bet would be to just factory reset with the sim card in it. Taking the sim card out and putting it back in has apparently confused your tab and the only way to fix it would be for the sim to re-validate with your carrier after seeing a fresh install. you might be able to try the setup wizard but i dont see that revalidating your sim since its already verified. Factory reset isnt end of the world, if you start rooting and flashing custom roms you'll get real used to resetting up your tab/phone in minutes from a fresh wipe.
