After flashing a GB rom I am no longer able to access the T-mobile network. My sim card is no longer detected and I have absolutely no network connectivity. I have tried to flash back to froyo and back to other GB roms without any success. Any help would be greatly appreciated.

Check under phone info and see what your baseband version is.
There is a dumb little problem that I've seen pop up a few times where the IMEI goes missing and the baseband number with it... then this happens...
If the sim card isnt being read at all, as in (please insert sim), shouldnt matter with imei as imei has nothing to do with service. Even with a null/ 000000000 imei, calling, texting, data all works. Its probably your sim card tray.
If your sim card is read, but just no bars, etc, then try reflashing and factory resetting.

My baseband version is "unknown" and my phone says I need to insert sim. If it is my sim card tray, then how do I get it fixed? Thanks.

I had the same problem a month ago, and found a good handful of threads on it. Most of those threads also reported missing base band and imei. I resolved it by flashing back to 100% stock and starting over. Not saying it'll fix you for sure but it worked for me.

Had a similar issue a few months ago, flashed a different ROM and it went away. Not sure is it was a coincidence but recently upgraded to stock KJ6, everything was fine for a few days then all of a sudden no T-Mobile network/ Manually logged on, crappy signal, white 4G icon, calls dropping, I can hear caller, they can't hear me etc... Figured the network might be swamped due to Thanksgiving holiday, waited a day but it got even worse. My wife's SGS4G meanwhile continues to have great signal- not a sim issue as I swapped hers in to my phone and it still sucked. Called T-mobile tech support, new phone arrives this Friday. They blamed it on the upgrade to VUVKJ6, I wan't going to argue with them as I didn't have the phone insurance (I do on the new one) and they said that because it happened after the KJ6 upgrade it was on them .... it only cost me $20 for a brand new replacement.
I do have to say that T-Mobile customer service kicks ass.
Try flashing a different rom to see if itll fix the problem. The last resort would be resoldering. Try all other options first.

Thanks for the replies. I tried flashing to 100 percent stock and nothing changes. It doesn't matter what I flash to or how many times I restore factory setting and wipe all user data. I always end up with a phone that doesn't detect the T-mobile sim card or the network. I requested an exchange for 20 dollars since my phone is still under warranty... I hope I will be able to flash to a different ROM next time without the same problem.

I seem to be in the same predicament after flashing KJ6.
Spent the whole day flashing different ROMs, to no avail.
Guess my only option is contacting t-mo, and see if i can get a replacement.
Will they know if i updated through Kies, or Odin?
i'm in the same boat. bought my phone unlocked through amazon two months ago and upgraded to stock KJ6 through Kies when tmo released it. worked fine until two days ago. SIM works in other phones, IMEI number looks good, APN settings look good. Haven't tried switching to other builds because all the threads I've seen here at xda and other forums seem to show that doesn't change anything.
didn't realize how much i liked my phone until i went to the backup motorola zine the last few days. bogus.
Before you send your phone back make sure it is 100 percent stock ROM and not rooted. Also, factory reset and wipe all user data.

Thanks.
I did know all that. Just wasn't sure of they could still tell I didn't do it through Kies.
Anyway, just contacted T-Mobile, and my new phone should be here Monday.
Awesome customer service.
My t-mobile exchange phone arrived and I upgraded to latest GB via Kies and then I flashed Dr. Honks latest kernel and everything works. No network or sim problems.
I am really happy with T-mobile customer service too. My phone arrived only 3 or 4 days after I requested an exchange. No questions asked.
From what I have been reading on the forums, it doesn't matter if the phone was upgraded via kies or flashed via odin. The phone just has to have 100 percent stock
Damn having the same problem,no sim card detected.No baseband,no IMEI.Went stock via Odin,nothing.Went to stock Froyo and still nothing :-(
sgs4g, same problem...only mine im sure is the sim tray. this was a refurbished phone i bought from craigslist, brand new.
stock froyo, gb, rooted ocataine, doesnt matter- every few weeks it would say insert sim..
Now im just gonna call and tell them it happened after the upgrade because it was there faulty phone to begin with.. now how can i go back to perfectly stock? and does that mean i should send it back on froyo or gb?
I've had/am having this problem. I brought my phone to the UK and I had this issue when I tried a new carrier. 3 weeks ago I was able to plug my phone in to the charger and then put it in airplane mode and out and I had no issues until I tried a 3rd carrier today and now the issue is back and my previous fix isn't working. Because I'm not using T-mobile and bought the phone off of a friend I'm hoping I can find a way to fix this without sending in my phone because that really isn't an option.

after looking around a bit more and flashing a few roms unsuccessfully I found this http://forum.xda-developers.com/showthread.php?t=1323973&page=6
I removed the battery and sim from my phone for 10 min. Put everything back in, booted and everything is working as it should be. Hope this helps.
Glad you found the battery fix, I have stated that fix in a couple of threads, and started a thread called No carrier signal + IMEI problems = Take out your battery, but it has been pushed down like 3 pages cause no one comments on it.

The link you posted is no good, can you tell me where it was at? Also what are all of the steps to get SIM or IMEI working again just the remove SIM and Battery for 10 Minutes?
There are a lot of people who flash custom ROMS on Telus, Rogers, Wind and T-Mobile who have this problem and if what you are saying works then that needs to go viral. What is strange is that some have the issue same ROM and Phone and others don't it's a hard issue to try an troubleshoot to say the least.
Any more info on this subject would be awesome bro.
Thanks,
Jk
Hey guys.
I just got my i535 Galaxy S III a few days back, and decided to root it. Paranoia wasn't for me, so I tried CM10. Somewhere along the lines of that, my 4G stops workings. Luckily, I already backed up my IMEI.
I've been trying for a few hours to fix it. I already used the following methods of "fix":
Restoring backup from CWM
Going back to (rooted) stock,
Changing my Mobile Networks settings around,
Phone Info (Couldn't honestly find out what to edit in there, or if anything WAS editable),
restoing IMEI
From what I can see, I have my IMEI, MEID, and phone status reads: "Normal". Yet, when I look at my bars, I get 3 of 3G, instead of my usual (and what my other galaxy S III devices are running currently.)
Samsung's firmware mirror site is down at the moment, so I haven't tried that last resort before returning to Verizon, but do you guys have any thoughts?
Thanks
I have a similar issue - except my phone does not recognize the verizon network. I was rooted with CM9. i've since replaced the SIM and flashed to factory rom. I am seeing my IMEI number, so I don't think that's an issue (right?).
I took it to the verizon store and they want to trade it in, which i am fine with
My biggest concern is removing any trace of root.
I had the same issue when going into cm9, got a new sim yesterday and I got my 4G back.
I'm in the same boat. Just gonna get a new sim card and hope that fixes the issue
I'm not sure if this is a network issue or a phone issue. I just got a replacement phone from Google. Popped in my sim 2 days ago and it was working fine, OTA 4.4.4 updated the same day. Came to work today and it was working for about an hour, and now it says there is no connection. I go to the "network operators" list and I only see ATT on there, which doesn't work for me since I'm on T-mobile. Other people in my building have T-mobile too and their phones work just fine, so I'm guessing it's not a tower issue.
I've tried restarting the phone as well as taking the sim out and reinserting it. Anything else I can try?
Phone is stock, not rooted, not flashed with a new rom.
Hey guys,
So when tmobile dropped nougat for the s7 I restored stock/unrooted my phone completely and then upgraded to nougat. Since then though my phone at times will stop reading my sim card all together. now i have never had this problem until after i came from the g930u rom. Sometimes it'll read my sim, but sometimes itll just stop out of the blue. i could be doing almost anything. i went today to tmobile to make sure my simcard wasnt acting up. also my phone can read my SD card just fine . So im not sure if its a modem problem or what but can someone help plz, i dont want my phone to be a paperweight mp3 player? thank you.

Hi mate
You may have better luck asking here:
https://forum.xda-developers.com/tmobile-galaxy-s7
This is the international S7 forum ( Exynos)
Hi all, new noob member here with hopefully a simple question. I bought an unlocked S20 with tmobile firmware about a month ago. I'm using a verizon SIM card and everything worked fine until yesterday when Tmobile sent out an update. At first I had no mobile data but could still send texts. After searching, i saw under my SIM card status it said IMS not registered. Not knowing much about this stuff I was thinking that maybe I needed to flash verizon firmware onto my phone and that would fix it ( I have not done that yet). I went to the verizon store and got a new sim... same issue. I also found a website listing access point details, I plugged in all the information and now I have 4G but i am still unable to send texts. I'm wondering if anyone has any ideas as to what my problem might be. I'm trying to avoid flashing new firmware onto my phone because I don't have a great understanding of how to do it, and i really dont want to brick my phone. Any suggestions would be appreciated.
