Hello. I'm just looking for some information regarding activating a used iPhone with Koodo Prepaid. Is it possible to buy a used unlocked iPhone and use it with Koodo prepaid? Do all iPhone models work with Koodo prepaid? I would ideally like to get an iPhone 4s or higher. Can I buy a used Koodo iPhone that is locked to Koodo postpaid and activate it on prepaid? Or does it have to be an unlocked iPhone? I am already with Koodo prepaid, and my phone takes a regular sized SIM card. Can I just transfer my account to a micro SIM card that fits in the iPhone? How? Is it possible to do this without a phone, or would I have to have the iPhone with me already to activate my account on the new micro SIM card? Thanks for looking.
