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 honestly tried to find the answer to this everywhere before posting. I already have the unlock code from HTC and Tmobile. I simply need to figure out how to unlock the phone.
The instructions I received with the unlock code said that the phone would notify me that the SIM is unregistered and I would put in my unlock code at that point. I assume this is only the case on a vanilla version of Android or whatever the current official release is.
As you may have guessed, I have my phone rooted and have been running CM for a while. When the prepaid SIM is in the phone CM does seem to realize that its there and there is a SIM tool app but it does nothing. I have flashed to a couple different customer ROMS including dwang and a couple older version of CM.
Is there any way that I can actually unlock my phone without having to unroot and go back to the official android release from tmobile?
Thank you to anybody that can help me.

Is it The AT&T Prepaid sim card. If it is then i don't think it would work. i have an unlocked g1 with an AT&T sim card and i unlocked it before rooting. So guess u have to do the same. hope i helped
Right now I am trying with a TracFone SIM card but I could try with an AT&T card from a friend in a couple of days. I don't even really need to get the service to work at this point.
The two things I really want are just to be able to unlock my phone and backup my contacts onto a secondary SIM card and I am having no luck doing either.

I am on AT&T and when I put the Roger’s sim card in, I could not unlock the phone from the lock screen. After I followed the directions to unlock the phone, The SIM card from Rogers could be used but I get “SIM not provisioned MM #2”. Has the phone been unlocked correctly?
This is my first android phone and I would like to have the phone unlocked to use a Roger's SIM card in case Rogers receives updates before AT&T, that I may update the phone. I know I could root the phone, but I have never done that and I bad at following directions. I checked software updates and the phone did not find any updates with the Roger's SIM card.
I believe updates are based on your CID and have nothing to do with what SIM card your using.

The first part, just means that your SIM has been deactivated, or hasn't been activated for use yet. And I believe the phone has been unlocked correctly if it recognizes Both Sims.
Updates are tied to your handsets CID, so unlocking will not allow you to get updates from other sources/networks. You'll still have to wait for AT&T to release your update/s.
Hi all;
got my sim unlock code for the nexus 6. when i put in a non carrier sim and boot back up no menu comes up for me to enter the unlock code, just says no service, if i put the original carrier sim back in it works fine..any way to manually invoke the unlock code menu so i can enter it or any other tips..thanks in advance
I can't help with this but it may help others to say what carrier you're locked to..
Sorry..iT's locked to rogers in canada
Since the phone was already used on Rogers, perform a factory wipe to use a new carrier's SIM
My Rogers Nexus 6 came unlocked out of the box. I expect yours is as well. I have never heard of a locked Nexus device sold by a Canadian carrier.
Weird
..just says selected network (telus) what im trying to connect it to is unavailable. Factory reset at this point too
Hi All -
I've searched everywhere for the answer to this and haven't been able to find it, so I figured I'd post here. This is the scenario:
1) I have a Moto X that is locked to AT&T
2) I wanted to give the phone to a friend who is on Sprint, so I paid for an unlock code
3) Even after unlocking and inserting the Sprint SIM, I still received the "SIM Network Unlock PIN" message
4) I now want to basically restore the phone completely back to the way it was (locked to AT&T), so it can be used with an AT&T SIM
5) I flashed the phone using RSDLite and the correct ATT ROM, but after the flash finished successfully and I insert a valid AT&T SIM, I still receive the same unlock message.
So my question is basically, can I get the phone completely back to being locked to AT&T, essentially the way it was out of the box? I'm also willing to flash it with Cyanogen or another ROM if that would help.
Any help is greatly appreciated, thanks for your time.
I have same issue, I had my Sim working for a couple of days but I wanted to return to stock to receive further updates and I flashed it with correct at&t firmware package but now there is a popup every time when I insert Sim about unlock code and I am stuck ... I think that's because of erasing modem st1 and modem st2 during flashing with RSDlite ... Is there anybody to suggest something helpful
I flashed my sprint note 8 to a unlocked firmware, and it's using a tmobile sim.
After the news, I try to switch back. I flashed the firmware N950USQS2BQL9_N950UOYN2BQL9_SPR using ordin. But when the phone boots up, it's T mobile, with the splash screen and my tmobile app and EVEN a Device Unlock app.
So I took out my sim and tried flash with no sim inside, it's still T mobile. I don't have the original sprint sim card anymore. And the present of the Device Unlock app is driving me crazy, and I also scared that the ota will brick my phone.
Please,anyone know how to fix it?
Are you flashing using the app data file?
Do you have any other non-Tmobile SIM card to check if your phone locked itself to Tmobile?
You might have the device unlock app installed on your phone, but this doesn't mean the phone is locked to Tmob.
Insert a non-accepted SIM card as here: https://www.unlockunit.com/blog/network-locked-t-mobile-usa/
And let me know the message your phone displays.
Also, check your IMEI if it's recognized by T-mobile servers with their own service here: https://www.t-mobile.com/verifyIMEI.aspx
