I want to update my phone number with T-Mobile but I’m not sure how the process works. Can I change it through the app or website, or do I need to contact customer support? Any quick steps or tips would be helpful.
You can online update the T-Mobile phone number by accessing an account in the T-Mobile web site and under the section Manage accounts you will see an option of updating the line that you wish to change. Alternatively, you may call the customer service by dialing 611 using your T-Mobile phone or visit a T-Mobile store and make the change.
Changing your T-Mobile number: To update your T-Mobile number, call 611, or visit a store, pay a fee of 15 dollars, record voicemail, and app updates and re-set up accounts that connect to your former number.
