Does ATT phones work in Canada?

It will work in Canada, but you will be charged about .79/minute for each and every minute. No nights and weekends, no mobile to mobile coverage.

There is no email address for customer care. You can call 1-800-331-0500 from a landline if you need to get your phone back on.

You don't need to set anything up. Just reactivate your phone. and remember that those minutes add up really fast at .79 each!
