Hey there, @shakiralouise
With Flex Pay, once your 24 month airtime plan comes to the end of its contract period, you're welcome to switch this to a different plan, or cancel and take the number elsewhere.
If your device plan still has time left though, you would need to wait until this is paid in full before you can switch to a new plan including a device.
