We are planning to buy an iphone 5c from the Apple Store to replace an old phone (with Koodo). According to Apple "You can activate and use iPhone on the supported GSM wireless network of your choice. The unlocked iPhone 5c and iPhone 5s will not work with CDMA-based carriers. An unlocked iPhone 5c or iPhone 5s may not support 4G LTE networks in all other countries". Does this mean we can't use it/activate it with our current Koodo account?
