Using T-mobile phone on AT&T.
So T-mobile is offering LG G3 really cheap with no contract. I would like to unlock it and use it on AT&T. My question is whether it would work on AT&T properly? I heard that AT&T have a lot of same bands as T-mobile but there are slight differences. Before deciding on the purchase,I have to make sure that the connection won't suffer as I use my phone daily on train and busses.
