I'm currently on 3 year contract with bell and I have this really crappy phone I hate
I still have 2 more years of contract and I was wondering if I could switch my phone
Is this possible?

You can switch your phone anytime you want, but bell isnt gonna give a discount like they do to new customers. You would have to pay closer to the real price of the phone, but i advise you call and complain to bell and they may be more agreeable.
