With a change of responsibility, account holders can let another person take ownership of an existing T-Mobile line or account. Only the current owner of an account can authorize an ownership transfer. It's a good idea for both parties to review the T-Mobile Terms & Conditions before the change of responsibility. Please note that you will only be able to move a number if it has been active on the current account for 90 days.
- Contact us to begin the process.
- Both the new account owner and the existing account owner must call T-Mobile to authorize the change of account ownership.
This process is strictly for transfers involving at least one business line.
- 21 lines or fewer: Print and sign the Business Change of Responsibility form (PDF best experienced with Adobe Acrobat Reader). Send the completed form to BusinessCare@T-MobileSupport.com or fax it to 1-877-214-5937.
- 22 or more lines: Contact Business Customer Service for help with transferring ownership.

- The line must remain active and keep the original number associated with the EIP.
- Both accounts must be in good standing; neither can be past due, delinquent, or in write-off status.
- You have 60 days to move an EIP balance after transferring ownership of a mobile number.
- Both parties have 48 hours to accept the balance transfer or it will be cancelled.
- It may take up to two bill cycles for the changes to go into effect.
