Available balance check methods
T-Mobile offers several ways to check your account balance and data usage. Prepaid customers can use short USSD codes like #225# (#BAL#) for balance and #932# (#WEB#) for data. Postpaid customers get the full account view through the T-Mobile app or the T-Mobile website.
USSD codes work on any phone without mobile data and are free to dial on the T-Mobile network.
