I was on the phone with the AT&T cancellation department today and mentioned that I was interested in porting to T-Mobile, who offers free roaming in Canada. The rep told me that AT&T last week rolled out "Canada Roaming Bonus", similar to the Mexico Roaming Bonus that they began offering late last year. The rep said that it's a feature that's not publicly advertised. You have to be on a Mobile Share Value Plan or the new unlimited plan, but for no extra charge, you get unlimited talk and texts in Canada as well as 1GB of data. I'm still on a grandfathered FamilyTalk plan, so she was trying to get me to move to a MobileShare Value plan and get the Canada Roaming Bonus, but it still wasn't worth it for me, since all 4 lines of my lines are still under contract.
