Hey @jack0194 - that depends what kind of plan you're on. If you're on a normal 24-month postpaid contract, you'll be able to re-contract onto a new phone with a new handset at the end of your current contract.
If you're on a Flex/Lease plan, you'll need to return your device to us.
If you want us to check what your options are, feel free to shoot me a private message with this info (for privacy reasons):
