Sorry 1 you can't switch from Rogers to other networks until you have unlocked it . First of all, check your iPhone is locked or an unlocked phone by just inserting another network sim card with it . If your iPhone not accepts other network sim card, you need to unlock your iPhone from carrier lock to use it with other GSM carriers . If you wish to unlock your iPhone, use Remote unlocking method . You can get iot from a ny of teh online vendors like SuperUnlockCodes.com to unlock it . After unlocking your GSM iPhone , you can switch to other GSM carriers like fido, telus not with a CDMA carrier like Bell .
