Ok so I have this note 3 that Is tmobile and I know it's a note 3 tmobile cause it says in the back. But I try to but in my tmobile Sim card in and it won't read it. Just to make sure my Sim card wasn't working I tried it on another tmobile supported phone and it worked perfectly fine it read the sim. But not on my note 3. Also one thing. On my notifications it says sim card not inserted but once I do that notification goes away but it doesn't actually read it. I've turned on mobile data on and data roaming I don't know what else to do I've done everything.
