...rogers or does it just work? im going away on vacation and i need to be able to call home to canada every few days. i went to buy phone cards so my phone would have money, and the lady at the store told me that i had to call into rogers and tell them i was going away and needed to buy roaming? im a little confused, can some one help me out? do i need to pay separate for roaming or will money i buy on phone cards cover the bill?
