I have a contract for a voice plan with Telus that is up at the end of the month. I like my plan, but am interested in a new phone. At the same time, I don't want to commit to another 3-year contract. I'm considering buying an unlocked iPhone from Apple and just putting a Telus sim card in it (using only wifi for data) and keeping my current voice plan on a month-to-month basis. Do you think this is possible? Also, I've heard that when you buy an unlocked iPhone from Apple, as soon as you put a sim card in it, it's locked to that carrier? Is this true?
