SMS messages cost to receive with unlocked iPhone?
I heard that apparently with AT&T contracts, iPhone users are charged for receiving SMS messaging. I am using an unlocked iPhone using Rogers in Canada and I had assumed that I was not charged for receiving SMS messages because Rogers says they are free to receive. But I was thinking that possibly it has something to do with the phone itself (since it threads SMS messages together like Gmail). Does anyone know how it works and if you are charged for receiving SMS messages on an unlocked iPhone?
