Good Day, I live in Belleville, ON. I currently have two Blackberry Curves. a 9320 & 9300. I checked my Blackberry's and the sim cards will definitely not fit the iPhone. I just recently bought two iPhone 4S's on eBay that are for the Koodo network and I would like to keep the same accounts. I need new micro sim cards and was wondering if I can purchase them (but where?) and keep the same account open as I have money on the accounts. Is there a certain procedure to follow? Need some expert advice and would be greatly appreciated.
