The issue is like this. Now im in a three years contract with Telus. But I want to switch to Nexus s. I want to know can I keep my plan and phone number, then switch to a new phone. My currently using phone is a blackberry with no Sim card slot. So can I transfer my phone number into a sim card? Im in Canada, where to buy Nexus s online is the best? I saw the price in Amazon is about $660, is this price good?
