Hello AT+T,
Â
I now own an i-Phone 3GS, legitimately paid for from the Vietnam Apple store.Â
Â
I’ll be relocating for college to Columbus, Ohio in the tumble and it seems which it will be probable to operate my iPhone with AT&T, though I have 2 questions:
Â
1) What would be the many befitting AT&T devise which would let me operate the 3GS network and has enlightened intl text/call rates?
2) After relocating to the US can I still switch my SIM cards? (i.e. when I go home to revisit my family might I take out my US SIM and operate my Vietnamese SIM for the generation of my stay?)
