Porting my number
Currently I am on my boyfriends phone plan from at&t and because we have decided to go our separate ways we've been trying to figure out how to get off the shared plan. For financial reasons I am planning to switch over to my parents family plan, at T-Mobile, and hope to keep (port) my number. What all do I need to port my number (and hopefully device which is a Samsung J3 that is already paid off) over? Also, since it's his account do I need to have some form of permission from him to port my number?
