With the recent announcement of a couple of Android international devices (current Motorola XPRT and up coming Motorola Photon 4G), i'm trying to understand the benefit and cost savings. i'm assuming these can do both voice/text and data internationally (right?) i understand that these phones has the necessary GSM radio to connect to the non-domestic towers, but what does it mean cost wise? do i have to change my current plan of Everything Family plan? or, is it a monthly or prorated fee for when i go international with the device? what would that fee be? is it a one time charge or roaming charge or both? thanks in advanced.
