Yes they need the newest sim cards from t-mobile...just go in and tell them you have an old sim card and they will replace for free.

[Q] NO SIM issue after upgrade

Hi guys,
I got a Samsung T989 T-Mobile yesterday with stock Gingerbread Rom, i flashed recovery cwm and rooted the phone.
I flashed a 4.1.2 rom, everything was working good except that the phone doesn't detect my sim card.
I Flashed various roms and various modems, restocked to 2.3.6 and 2.3.5 still having the same issue.
I also tryed some tested sim cards and still no sim detected.
I don't even know wich baseband came with my GB version, is there a way to find the good stock rom ?
Radio tryed :
UVLI1
UVKL1
UVKID
UVMC6
UVLDE
UVLE1
UVLI4
UVLH1
Any idea ?

Today i made an upgrade from kies to 4.1.2 UVMC6, still same probleme.
Is it a hardware probleme ?

Little up guys ! i flashed all supported firmwares on sammobile, none of them get the sim to work.

I am not sure if this will help you, but I had some phone not recognizing SIM type problems too, and the problem was if the SIM card was not in the exact right spot the phone would not recognize it. So I would try to scoot the SIM to one side of the slot or the other and that fixed it. Also if I dropped the phone it would say "SIM card removed" "restart device" and I would have to reposition the SIM card. I hope I helped someone

Hi, did you manage to find a solution for this problem as I have been unable to resolve a similar issue. My sim error appeared randomly on the latest unrooted stock btu build. I have even replaced the sim reader. Any suggestions would be appreciated.
Thanks.

greetings
i had the same issue, quite frustrating.
I bought my Note2 with broken Display, after i repaired it cut my sim to a mico sim, tried it out and got "No Network". So i replaced my 2 Years old Sim with a new micro-sim and with no luck.
After some error diagnostics i found out that the IMEI was broken, well f**. One month later is repaired the IMEI at some Mobile Service-center and the guy demonstrated that the phone now works. Well ok, i was. At Home i inserted my Sim and it didn't worked. I tried my brother Sim cards (2 old Drei Crads) and they worked, now i was like WTF.
Tested Sim-Cards (all Sim mentioned below are from Austrian Carriers)
T-Moblie (2Years old) => ok
A1 (2Yeas old) => ok
3x 3AT (old Sim Design before 2014) => ok
neu 3AT Sim Card since 2014 => NG
I already replaced the sim but with no luck since my carrier gave me the same new Sim Design.
Today i found the issue, the IC or contacts of the new sim are a little bit dipper molded in the plastic. I put a small piece of paper on top of the sim, so the sim is forced down on the simslot contacts, so far i had no issues. I will report this to my carrier and see what thy gonna say.
Hope dat helps, cheers.
FW: Stock 4.1.1 rooted

My samsung note2 N7100 having a problem it keeps asking to insert sim while it shows network and exact time. Whenever i tried to update it failed. Please help me.

[SOLVED][Q] IMEI and Baseband unknown. I don't have a backup.

[SOLVED] I put my phone in airplane mode and my IMEI/Baseband came back, cheking the service menu I went to *#2263# and saw that "LTE Preference" was enabled. I clicked on Automatic and problem fixed. Probably a ROM bug? Who knows.
Hello there. I've been a reader of the XDA forums for some time but I never had any reason to create an account to post on the forums.
A few weeks ago I got a SGH-M919 as a gift, the phone only had a few months of use and I took it with me, everything worked fine except for the fact that I couldn't get 3G/4G (Not even EDGE), I was only able to connect to the GPRS network and I couldn't change the carrier (It always gave errors like "Unable to connect. Try later" and such). Although the phone is (apparently) quadband (I don't live in the US), it just didn't work but I lived with it.
Yesterday my phone was low on battery and I turned it off, a few hours later I turned it back on and it couldn't connect to the network, I went to the network options and once I pressed the screen to enter the Mobile Network options, I got an alert saying that I must have a SIM to access those option. At first I thought that the SIM got damaged somehow (This isn't the case since it works perfectly fine in another phone) but after a few minutes looking around, I checked the IMEI and instead of the usual number, I got a null/null message. My first reaction was to google what exactly happened and the answer I received was that the Baseband (Which is also Unknown) and IMEI are stored in a folder called EFS and that it got corrupted. Sweet. I looked for solutions but the main two I got (EFS Pro and ADB nvrestore) require a backup of the EFS (Which I don't have).
The other solution I got was to restore to the stock ROM (M919UVUFNH7) which I'm currently downloading from SamMobile (Sorry if this is considered spam). The phone is not rooted and has the stock ROM, it came with a CWM folder inside the internal memory with an .img file but it doesn't have CWM intalled. I've never upgraded it (Not sure if it came with that firmware from the store if it matters).
I live pretty much in what can be considered a "3rd world country". So I cannot send it to Samsung nor I have access to dollars.
Another question is, the phone was gifted to me already unlocked, I don't know if it came unlocked from the original carrier or if it was unlocked via a code or whatever. If I restore to the stock will it lock my phone to T-Mobile again? Would I be able to use it without a SIM card if it gets locked? It's impossible for me to get a T-Mobile SIM on my hands should I ever need one. In the worst case scenario that my phone gets locked, can I get it unlocked by flashing a custom ROM?
I have so many newbie questions that are already answered in other threads, but since it's a lot of information I want to get it as specific as possible to avoid breaking my phone.
If someone can help me with this issue, I'd really appreciate it.

i having same issue in M919

Do you guys get a message in notification bar about sim car removed or something about a sim card? Also, it doesn't matter if the sim card works in another phone. This device has a little issue with being picky with sim cards. If it's a cut sim card, get an original micro sim card

Hi, thanks for answering. I don't get a message about a removed SIM card. I'm also using an original micro SIM.
I already downloaded the Stock ROM but I haven't flashed it yet.

This is a known bug of the s4. It is a hardware problem and I have yet to find a solution. If you google it you will find many threads on different forums addressing this issue. Again, no known solution

Any answer/idea about my issue? . Sometimes I can access Mobile Network Options, sometimes I can't. I can't configure the APNs (They delete themselves after I click on save). Phone Serial Number didn't get deleted (Which is stored inside the EFS folder as far as I know). I also can't select a Network Mode. I click on GSM/WCDMA/LTE but it changes automatically to nothing.

That's what I said? One solution is to change sim cards if using a cut sim card to use an original micro sim. It's worked for a friend if someone I know and also for others on XDA. It's not the solution, but works for some

I would get a new sim anyway if I could. Flashing stock firmware wouldn't hurt as well

Before trying to flash it, is there any risk of getting simlocked again? I wouldn't want to get my IMEI fixed just to realize that my phone is locked to TMB again
UPDATE 1: My IMEI and Baseband randomly got back (My IMEISV was still missing) but after I restarted, they got deleted again.
UPDATE 2: Rooted, went to EFS, didn't find nv_data.

No SIM card inserted after unroot and upgrade

As above really. Not really sure if it's a hardware or a software error here. I've read that the sim card readers can be a little fragile but there was no fuss during the removal so I would be surprised if that was the issue. What I'm wondering is if I've missed something when un-rooting my phone.
I was using a custom ROM, all working fine, but I've got a new phone so I decided to unroot my old one to sell on. I flashed my original firmware using the LG Flash Tool. Firmware file is "UK Vodafone 16G D85510A_00.kdz". It all went great as far as I could tell and I started upgrading. The final upgrade was the install of Marshmallow 6.0.
In order to find out if my phone was locked or not I put my Wife's SIM in. Rather than coming up and asking for an unlock code it simply stated that there was no SIM inserted. I thought that was potentially down to the wrong SIM being in but when I tried mine I was met with the same error.
Have I missed something? Did I need to change the baseband or something during the process?
Any help would be greatly appreciated.
Thanks

I've had kinda same problem since a couple of weeks ago...eventually SIM card gets read for a short while and get back to that No SIM card inserted state.
It has happened with any ROM as well as OG FW flashed through LG tool.
I haven't tried another SIM on my G3 but my SIM does work on other cell phones.
