i have a nokia dual sims phone, with a rogers card...?

[gina]

i live in ny, but when i went to canada it says no service, and in the states its saying no service....what am i doing wrong... i couldn't even put minutes on in in montreal, with a voucher. i was suppose to get free minutes with the card, but that never happened either....i go to networking and they can't find one..i have a canadian phone number and address on the phone, so i should have been able to use it in montreal
