Currently i have a blackberry bold on a 3yr contract, is it possible for me to go buy a iPhone online ( classified site ) and just pop my sim card and that be it, or would i need to do anything in preticular.
It all depends which iPhone you are looking at & it MUST be unlocked or locked to Rogers to work with Rogers.
A iPhone 3G/ 3GS uses a Normal Sim card. A iPhone 4/4S uses a Micro Sim card. The iPhone 5 uses a Nano sim card.
Once you buy the phone from whoever you buy it from, buy a sim card of which model you need & activate it on your line. You can do this by calling Rogers & having them activate the sim card or do it at the Rogers plus store. You can also buy the sim card before hand & activate it on your acount & then meet up the person & test the phone out. This is the best thing to do.
