Because then you won’t mistakenly use a card not linked with T‑Mobile Dining Rewards when dining out and miss out on rewards.
Members are encouraged to keep more than one credit and/or debit card linked and up to date in their T‑Mobile Dining Rewards Account Center. You can earn cash back through any credit and/or debit card you link and use at T‑Mobile Dining Rewards participating restaurants. Members with more cards linked tend to earn more cash back.
Make a practice of updating your card information in your T‑Mobile Dining Rewards Account Center any time a card issuer sends you a newly numbered credit or debit card.
If the card number remains the same, but the expiration date or security code changes, that’s no problem. Our members are never asked to provide this information.
