I have been with Koodo for almost 3 years now, and I have had the Iphone 5S for that time. I am trying to upgrade to a Iphone SE 64gb, but online, there is no tab available. It only has the retail price of $600. However, when I DO NOT sign into Koodo, there is the option for the Iphone SE 64GB for $0, on tab medium, for $15 for 24 months. Why can't I be part of this tab plan?
