Id like to know if it will work if i decide to switch to tmobile or att if i fully buy the phone. I know before with the iphone 5 models if you had a verizon iPhone you wouldnt get LTE if you unlocked it and used it with att or tmobile. I just want ot make sure if i switch to tmobile ill still get the max data speeds (lte) available with both att or tmobile. also if i do it the other way get a tmobile iphone can i use it on verizon network if its unlocked without any drawbacks? thank you!
