Change your phone number

There are a few reasons why you might want to change your wireless number, such as if you're receiving calls for someone else or if you recently moved. 

Things to keep in mind

• Changing your number deletes all voicemail messages. For detailed steps to set up a new voicemail box visit our Voicemail page.
• Phone number changes can take up to four hours to complete. Once complete, you'll receive a free text message with the new mobile number.
• iMessage can take up to 24hrs to reflect mobile number changes.
• Caller ID systems for landline carriers can take up to three days to show the correct calling information.
• Update your contact number on any accounts that may have your number saved, such as notifications for bank accounts, social media, etc.
• It may take up to three days to have access to sign into your account on T-Mobile.com using your new number.
• Call records for the old phone number will no longer be available on T-Mobile.com.
• T-Mobile holds all numbers for a minimum of 45 days and up to 90 days, at which time the number will be available for reuse.
• For apps that verify using mobile number, remove two-factor authentication before changing the mobile number. After number change a third-party company may lose ability to send an OTP.
