My uncle passed a short time ago. My aunt now has an iPhone 7 that she wants to give to my mother who is still using a free flip phone. The problem is that the iPhone has already been disconnected, and was on ATT while my mom is on T-mobile.

When I go to the ATT website it says that you request the unlock online, but that the only thing that you need to do then is swap SIM cards to the new SIM card (no special process to go through like other phones).

I'm assuming that means that when you request the unlock, that ATT sends a command through the network to the phone.

Does anyone know for sure if that means that the phone would have to be put back on the ATT network, unlocked, and then taken back off of the network before it could be moved to T-mobile?
