From My T-Mobile:
- Go to My T-Mobile and log in to your account.
- In the section that shows your BALANCE DUE and DUE DATE, select ON next to AutoPay to edit your AutoPay settings.
- Select Edit AutoPay Settings and then the desired payment method (credit card, debit/ATM card, or checking account).
