I purchased a remanufactured 32GB iPhone 5 that has the A1429 model number. I know that the A1429 model from the factory is not compatible with the Koodo network, however, I was told by the vendor that this remanufactured phone should work on the GSM network. I cut my Koodo SIM card down to nano size and put it in the phone. It received the Koodo 3G network and I was able to make a phone call and access 3G data with it. Can I get it activated on my account and use it on the 4G network?
