A Change of Responsibility (COR) at T-Mobile is a process where billing responsibility for one or more lines is transferred from one person or business to another.  

 

This can involve an individual postpaid account or a business account.  

 

The process requires the consent of the current account holder, and the new responsible party must pass a credit check.  

 

The new responsible party agrees to adhere to T-Mobile's Terms and Conditions of Service, including any device return obligations if the service is canceled in the future.  

 

For business accounts, specific eligibility criteria apply, and certain items like the Equipment Installment Plan (EIP) balance may be transferred to the new account holder under certain conditions.

ADVISEMENT: 
 

Please follow this advisement that you need to know:    
 

 You agree to allow T-Mobile to transfer your number ending in 5835 to a new customer and for us to discuss this transfer with them. Again, you will remain responsible for the mobile number and all charges on your account until the COR is complete. If the transfer of this number results in your account being cancelled, any outstanding installment balance that is not transferred will be reflected on your final bill and must be paid in full. If you have Autopay set up, the installment charges will be included in the total amount on the final bill which will be charged to the card on file.
