If u take off the battery cover and it has a simcard(would be red) then its global. I would factory reset now though imo. Don't forget to back up your pics ect. Also have your battery above 75%
Beamed from my SteelDroid D3
It has a SIM card but it is white/gray. I will back everything up this evening and then do a factory reset. Should I take the memory card out when I do it?
