the phone originally came on 4.3 from eBay. its a T-Mobile note 2 the sim worked fine before I did what I did, just said invalid sim put an unlock code or cancel and continue using phone. so here is what I did I went from 4.3 to 4.1.2 flashed with Odin as well as cf auto root with it and I think it was at that point it gave me that "no sim inserted" I went to 4.1.1 lj1 just fine. I went to that firmware to unlock the phone but now the sim slot doesn't work anymore what should I do any help is very appreciated.

previously i was on stock .290 rom with unlocked bootloader. i decided to update and first installed ihackers rom and also flashed doomkernel and then after a few days moved to stock .108 via flashtool. uptill then i had no sim card inserted in the phone. now when i insert a regular simcard it is detected and works fine. but when i insert a LTE enabled sim card it is not detected and neither the phone restarts or shows rebooting warning upon removing the sim tray. any suggestions on what could be the problem?
i also had a stuck sim in the phone which i had to remove a bit forcefully and hopefully no damage done or noticed. could that be the reason? although a regular or non lte sim works just fine. is there any way to check?
thanks
any one? help!
Did u flash the right ftf for the c6903 or was for some other model?. Cuz flashing a mis-matched baseband might cause stuff like this.
Hi everyone,
I've been using an SM-920T 64GB Galaxy S6 bought from T-Mobile last summer. I did a permanent unlock using the T-Mobile application and since July I've been using the phone on the AT&T network. I just rebooted my phone today like I always do and upon restarting I got an "Invalid SIM Card" and it brings up a SIM network unlock PIN window that I can dismiss or enter a code into. What is going on?
I'm running XtreStoLite Deo 2.4 if that makes any difference.
Also, does anyone have the T-Mobile Device Unlock apk that comes stock with the phone? This is how I unlocked the phone in the first place but I don't have that app anymore since I run a custom rom, and the play store won't let me download it because I don't have a t-mobile SIM card in the phone.
Thanks!
Well for the benefit of whoever has the same issue. I flashed back the stock ROM via ODIN, ran the T-Mobile Device Unlock app, it said Unlock Unsuccessful in big, but right below it said the phone has been unlocked permanently. I put in my AT&T SIM and it was working again. Then I flashed back my TWRP backup and the phone remained unlocked. The non-Tmo ROMs get the unlock popup when a foreign SIM card is inserted, so getting an unlock code should work, but I didn't want to wait 3 days to receive one.

Can you tell me what ROM you used? I have the g920T also, and bought it USED unlocked from ebay, but it had the FRP (factory reset protection) lock on it. I had my US cellular SIM card in it, even though I was stuck at the "enter your previous used google account on this device" and the SIM seemed to work (saw the LTE bars above).
But the only way for me to bypass the FRP was to flash to the ROM to stock (which I used the G920T tmobile ROM) and I got to the home screen but now it says "Invalid SIM card. Network locked SIM card inserted" just how you were saying.
When I try using the Tmobile unlock app, it says "Server not responding. Please try again later." .
Please help!
I bought a Vodafone smart mini 7 recently, and I have rooted it successfully.
Then I tried to unlock it. So I downloaded SN write tool and tried to change its IMEI, but I failed because the phone could not connect to the computer correctly, some USB driver issues, or I used the wrong db files. So, the IMEI never changed, it is still the original one.
After so many attempts, I decided to buy a code. I paid for the code, but it doesn't work. I was told to reset the phone, change another SIM card and try again. At that time I realized I haven't put the Vodafone SIM card which was bought with the phone, maybe the phone need to be actived by a same brand SIM card. I put the Vodafone SIM card in my Vodafone phone, I found it was locked as well. That means Vodafone locked itself!
I flashed the preloader when I rooted it, and have a lot of failed attempts to flash IMEI. I don't know why can a Vodafone phone lock a Vodafone SIM card, and I would appreciate if someone can help me to unlock it.
I bought a used note 5 T-MOBILE 64 GB that was unlocked yesterday. My sim card was working fine. I installed TWRP recovery by ODIN and after installing it my phone boot-looped. So, I installed "no-verity-opt-encrypt.zip" file and rooted the phone with "BETA-SuperSU-v2.68-20160228150503.zip". After that the stock rom booted fine but I the phone turned on it gave the error that non-carrier sim was inserted and the sim did not work. I tried formatting the phone. Installed the nougat firmware updated it and the problem still persistes. Is there any way to remove Network lock? I would appreciate your help greatly
Are you on T-mobile now? I am, and when I called, they unlocked my Note 5 for free, and very quickly.
Just as the title says, my phone suddenly stopped recognizing any SIM card. Even though it knows which carrier it is. I've tried changing carriers and it still recognizes which carrier but won't connect to any network.
All other functionalities in the phone work. I'm currently on stock android 9. Any help would be greatly thanked.
first of all is your imei fine if yes just try flashing stock again
second if you flashed a custom rom and then try to go back to stock and then your sim is not recognized by the phone ( if the answer to this one is yes then flas the same rom again - this just happened to me so now i´m stuck with custom rom) i have the same XT1965-2 but mine is from mexico
