I am a current koodo customer with an android smartphone. I am considering purchasing a nexus 4 16gb from koodo. It is available in the prepaid phones section and the phones section. I currently have a monthly plan (not prepaid), but if I attempt to buy it from the phones section it requires me to select a plan. I was trying to just buy the phone and put my sim card into it. Do I need to select it from the prepaid phones section? It costs $50 more there.
