I plan to upgrade to from my old Nexus S to something more modern. All the phones I'm interested in take a smaller SIM card than I currently have. I'm a prepaid customer.
1) If I buy a new prepaid SIM of the appropriate size, what steps do I need to take to register it to my account? Do I simply need to enter some code somewhere?
2) Can I buy _any_ phone from a Koodo store and have it work with my prepaid SIM, or do I need to specifically buy one from the prepaid section?
