There has been a lot of confusion in the market with which phones can and cannot be used with Wind or Mobilicity. Both Wind and Mobilicity run on AWS (Advance wireless service) which is a 3G protocol competing with the HSPA or HSPA+. But its not GSM. This is where i feel the confusion is. T mobile USA (TMobile UK will not work), Wind Mobile and Mobilicity both operate on 1700/2100 MHz AWS. Most phones from these carriers will work with each other. T-Mobile also has GSM, so that's why i wrote most! FYI: Blackberry will make the same model twice.
1. HSPA + GSM - Rogers, Fido, Bell, Telus, Koodo, Chatr(they currently don't have data)
2. AWS - Wind and Mobilcity
Here is the list of phones from T mobile that will work with either Mobilicity or Wind. These are the current phones that T-Mobile sells.
