You may be looking to change your mobile phone number under your T-Mobile plan for a variety of reasons. Whether you are looking to avoid being contacted by certain people or you would simply like a new start, this article will walk you through how to change your T-Mobile phone number.

Changing Your T-Mobile Phone Number

As a T-Mobile customer, you are required to visit a store or call to change your phone number. From your T-Mobile phone, dial 611 or 1-877-746-0909 and follow the instructions. There is a $15 fee to change your number, unless you’re on a Pay in Advance plan.


Changing your phone number will take some time to complete, although it rarely takes longer than four hours. However, access to your My T-Mobile account and the display of your information on caller ID could be delayed for up to three days. As a reminder, changing your number will also require that you set up a new voicemail.
