I think it will be a waste to use Sprint Roaming(unless there is a reason) while our TP2 is a world wide phone and can take any GSM sim outside of the US only by changing a setting and popping a SIM in it. That is what I do, that is what I HAVE been doing
you can get some SIM's with data or rely on wifi...your call, but 2 bucks a min, I SAY phuk dat
