You mean for your wireless network?BUT do you get 4G??
I use cellular from my home wireless netork, and 3G just wouldn't cut it, not sure even AT&T 4G would.
Pretty sure I got 4G at St James, usually when im south of the base the only thing I do is text or make voice calls so I really didnt pay attention.
Why you say 3G wouldnt cut it, hell verizon hasnt even had 4G for very long here.
I found out some of the network speed is phone dependant, I recently got a new phone and it is atleast twice as fast as the old one.
