Hi, I'll be moving to the States in December and will be buying a new phone, with a new plan and a USA carrier. I saw an answer to a question that I would not need to pay off my tab if I buy a new phone altogether. Is this the case? Or would I still need to pay off my tab? Is there a possibility of Best Buy or Koodo buying my phone off of me? What's the best way to save money in this situation?
