The phone is verizon.
I can't find the app. Do you know which one? I been having a hard time setting up this device to tmobile. Tmobile and Verizon can't find the problem. The settings I use is epc.t-mobile.com and fast.t-mobile.com and the same mms message.

I will speak with my cousin tomorrow to find out,
I did it with him on his computer.
we found it on another forum, it was not on xda... try googling checking for Verizon note 2 sim unlock, and Verizon apn settings change app, I believe it was on the play store.
