Apparently T-Mobile's coverage map lied as I'm getting really crappy 4G at best (bad ping and maybe 1MB download speed, if that, usually goes down to EDGE) as their rep. on the phone said the tower was too far away even though their map said "excellent 4G LTE coverage". If I recall correctly, if you bought the phone in full from T-Mobile you can use it on any other GSM network, such as AT&T? I'm still in the 14-day window as far as cancellations go. Any idea how I would purchase service through AT&T (I know they have good service in Lake Worth, FL in my area)? Would I need to do that thing where you get the SIM card and purchase a 2-year phone/data contract? This is my first smartphone so I'm not too sure of the exact steps in this situation. Any help is appreciated.
