I picked up a Sprint Tab 3 and unlock code for cheap. I would like to use it on T-Mobile for data only. Thinking I could just swap SIMs, I tried to insert my T-Mobile SIM into the tablet and never received a message for the unlock code like I've seen in videos. Needless to say, it didn't work and tablet states "invalid SIM" on the bottom. Am I doing something wrong?
I tried to flash the T-Mobile img with Odin 3.09 and that failed. Is this not possible?
What are my options?
