Sorry I know you guys probably got this a lot, so I bought myself an iPhone 7 from Apple while I still had my iPhone 6S, it's financed and still being payed off monthly. (I did T-Mobile jump) I wanted to keep it to give to my girlfriend who has Metro pcs. Do I need to have it unlocked for her to be able to use it? Or can we just go to a Metro store, tell them it's unlocked (since Metro and T-Mobile are the same company) and be good to go? Thanks guys
