I am a yearly prepaid customer. I am traveling to USA. If I buy data booster for USA, do l need to turn on data roaming when I get to USA to start using? Will there be any welcome message to indicate I can start roaming? Can I use data with any of the major providers like AT&T or T-mobile without extra costs? Will I be charged any hidden roaming pay per use fees? Will there be additional charges added if I go above limit?
Thank you?!
