I have a brand new unlocked iPhone 5s from India. I checked if the IMEI number was compatible with all the Canadian service providers. Seems like its not compatible on any of the networks. I have an iPhone 4 right now. Is it possible for Koodo to exchange the micro-sim for a nano sim which is compatible with the iPhone 5S and also could the phone work on the Koodo network despite the IMEI number not being compatible.
