The T-Mobile FAQs

How do I use my T-Mobile coupons?

To apply the coupon, click the 'show code' button next to the code on this page, and paste it into the 'discount code or gift card' box at the checkout and click 'apply'.

How many coupon codes are currently available for T-Mobile?

At the moment, there are a total of 9 active coupon codes that can be used on the T-Mobile website.

Can I Use Multiple T-Mobile Coupon Codes at Once?

T-Mobile does not permit the use of multiple coupon codes simultaneously, a practice known as 'coupon stacking.' Since only one discount code can be redeemed per transaction, we suggest finding the best T-Mobile offer available. Usually, that promo code will apply to sale items, allowing you to maximize your savings even with a single T-Mobile coupon code.

What payment options are available at T-Mobile?

T-Mobile accepts all major credit and debit cards, PayPal, and digital wallets.

Why didn't my coupon code work?

Your coupon code might not work for several reasons: - It may not apply to the items in your cart. - It may only be valid for first-time purchases. - It may have expired.
