Ok so i dont need t get bashed but i have a question about service. I am playing in a hockey tounament and where we are playing service is BAD i am on 1EXV. Can i get better service if i change to GSM/UMTS or Global?
If you change it to GSM/UMTS or Global your phone won't work. GSM/UMTS is for using the device on GSM networks like AT&T and T-Mobile. Global is for roaming around in different countries.
... as a side note: I was just in the Caribbean and used GSM. In fact there was both CDMA and GSM that partnered with Verizon there. So If I chose "Global" it would pick the stronger signal and switch to it (CDMA or GSM). However, only the GSM offered the data service, so I set it to GSM and left it for my trip, even if it had less signal strength.
