Welcome to the T-Mobile Community!
How unfortunate that you would like to leave us.
It is of course possible to cancel your contract. When you apply for an early cancellation, you need to pay off your device and the starters fee of your remaining months all at once.
May I ask why you would like to cancel your contract with us? If there is something we can do to change your mind then please let us know.
