Verizon used to offer free roaming between USA and Canada. But these days they have stopped it. I checked the majors like T-mobile, Sprint and Cingular ie At&T but all these providers charge for roaming between US and Canada. Any good corporate deal ?
Yes AT &T is really very good and is worth using. I have seen several people using it and other than it will be very necessary understanding it well. There are different service providers but there are very less services providers that are very good.
