m not sure maybe Atnt and rogers our partners (OR) their the same carrier jusst different names have you tried putting a rogers sim card in an atnt phone. Try it im sure somthing will work
Hi yes your rogers sim will work in iphone only if it is unlocked one .Else if the iphone is locked to some other network provider then until you unlock your iphone you can't freely use it with your old rogers sim ....You can easily unlock your iphone using sites like Unlocking4U.com here they are providing remote unlocking service to unlock your iphone from network lock ....
