Bump. I know this is an old thread but i when i put it on Global i get LTE but cant recieve incoming calls. When i put it on GSM i calls are find but im Stuck with Edge data. Any way to use GSM/LTE together? When i access the hidden menu with *#546368#*991# n go to Feild Test>Modem>RAT selection i see LTE/GSM but when i select it i still et GSM with edge. Im trying to get this to work with MetroPCS/T-Mobile n we all know they are GSM now
