I am currently with Koodo and have an unlocked iPhone 5. About 2 months ago I got my phone completely replaced at the apple store after a deficiency with my original one. It really looks like and runs like new. No scratches, cracks, or chips. Now I would like to continue using Koodo, but upgrade to a Samsung Galaxy S7 Edge. Am I able to trade in my phone to Koodo to get some money back? If so, how much would I be able to get?
