About the Store
T-Mobile provides wireless voice and data service, smartphones, tablets, connected devices, accessories, and home internet in the United States. Its official offers can include discounts linked to eligible plans, new lines, switching from another carrier, or trading in a qualifying device. Some promotions are delivered as monthly bill credits rather than an immediate reduction at checkout. Eligibility, taxes, device connection charges, financing requirements, and the length of the credit period vary by offer. Check the full terms on the official offer page before placing an order.
How to use a coupon
- Open the specific T-Mobile deal and read its eligibility conditions before shopping.
- Follow the offer link to T-Mobile's official website and select the eligible device, plan, or accessory.
- If an offer requires a new line, qualifying plan, number transfer, or trade-in, complete each required step during the purchase or activation process.
- Enter a promotional code only when the official checkout or offer instructions provide a code field or explicitly request a code.
- For trade-in offers, confirm that your device model and condition qualify, and follow T-Mobile's trade-in instructions and deadlines.
- Review the amount due today, taxes, device connection charge, monthly service price, financing agreement, and expected bill credits before submitting the order.
- Save the order confirmation and promotion details so you can check whether the expected credits or discount appear on your account.
What to do when a coupon does not work
- Check the offer's start and end dates and confirm that the promotion is still available.
- Verify that the selected plan, device, new-line status, trade-in model, and account type meet all eligibility requirements.
- Confirm that you completed any required activation, number transfer, or trade-in submission within the stated timeframe.
- Read the full terms for exclusions, limits per account, required service duration, and whether the offer is limited to well-qualified customers.
- Some discounts arrive as monthly bill credits and may take up to two billing cycles to appear; check the specific promotion terms.
- If a code is rejected, check its spelling and whether it is intended for that product or customer group. Do not assume every public offer uses a checkout code.
- If an expected credit is missing after the stated processing period, contact T-Mobile support with your order number and promotion details.
Coupon stacking information
T-Mobile promotions have offer-specific terms. Some device offers may be combined with other eligible benefits, while others have restrictions or require a particular plan, trade-in, or new line. Do not assume two promotional codes or discounts can be combined. Check the terms of each offer and confirm the final order details with T-Mobile before purchasing.
Best ways to save
- Compare the total cost of the required service plan over the full promotional period, not just the advertised device discount.
- Check official trade-in promotions and compare the estimated value and eligibility of your current phone before upgrading.
- Review switching offers if you are moving your number from another eligible carrier; number-transfer and plan requirements may apply.
- Check whether an offer requires a new line or a higher-priced plan, and calculate whether the added monthly cost outweighs the device savings.
- Consider eligible AutoPay savings. T-Mobile advertises a $5 monthly discount per eligible line, up to eight lines, when the account uses a qualifying bank account or debit card and meets plan requirements. Eligible payment methods and terms can change.
- Look at accessory promotions when buying multiple eligible items, and check whether the discount applies automatically or requires a specific purchase quantity.
- Compare device financing with the total amount due at purchase, and understand that paying off a financed device early may affect promotional bill credits under the offer terms.
- Check the official offers page periodically and read the terms of seasonal or limited-time promotions before committing to a plan.

Back-to-school season
Check for eligible phone, tablet, and family-plan promotions around the school season. Availability and eligibility depend on the offer published at the time.

Special discount programs
AutoPay discount
T-Mobile advertises a $5 monthly discount for each eligible line, up to eight lines or $40 total, when AutoPay is active with a qualifying bank account or debit card and the plan meets the requirements. Credit cards and digital wallets may not qualify for this discount.
Eligibility: Requires an eligible plan, active AutoPay, an eligible payment method, and compliance with T-Mobile's AutoPay terms. Eligibility may vary by account and plan.
How to claim: Set up or manage AutoPay through the T-Mobile account portal or app and check the plan and payment-method requirements on the official AutoPay page.
Device trade-in promotions
T-Mobile lists limited-time phone promotions that may provide savings through monthly bill credits when customers trade in eligible devices and meet the required plan and account conditions. The value and requirements vary by promotion.
Eligibility: Depends on the specific device, trade-in condition, qualifying plan, customer status, credit qualification, and any new-line or number-transfer requirements.
How to claim: Review the current offer details and trade-in estimate, then follow the official purchase and trade-in instructions.
Switching and new-line promotions
T-Mobile publishes limited-time offers for qualifying customers who switch to the network or add a new line. Some offers provide device savings through monthly bill credits rather than an instant discount.
Eligibility: Offer-specific requirements may include an eligible plan, number transfer, new-line activation, qualifying credit, taxes, and a device connection charge.
How to claim: Check the current offer's full terms before switching or adding a line. Confirm which carriers, plans, and devices qualify.
Accessory quantity promotions
The official offers page has displayed quantity-based accessory promotions, such as savings when buying three or more eligible iPhone or Android accessories. Availability and eligible items can change.
Eligibility: Limited to the accessories, quantities, and purchase conditions specified in the live offer.
How to claim: Check the official deals page and confirm the discount appears in the cart before completing the purchase.
Store policies and purchasing information
Shipping information
For devices and accessories ordered online, delivery options, timing, shipping charges, and any signature requirements depend on the order and destination. Check the delivery details shown during checkout and use T-Mobile's order-status page for tracking information. Store pickup availability may vary.
Free shipping conditions
A universal free-shipping threshold or policy could not be confirmed from the reviewed official sources. Check the shipping charge and delivery options shown for your specific order before paying.
Returns, refunds and money-back information
T-Mobile's published return policy generally allows device or accessory returns or exchanges within 14 days for purchases made at a T-Mobile retail location and within 20 days of shipment for orders placed online or by phone. Items must meet the policy's condition and packaging requirements. Refunds may exclude rebates, promotional discounts, applicable taxes and fees, shipping costs, or restocking fees. Promotional returns can affect eligibility for associated discounts. Authorized third-party dealers may have different rules, so check the policy that applies to the original purchase. Refund processing times can vary; the device-return support page says refunds may take up to 30 days to process.
Cancellation information
Service cancellations are typically scheduled for the end of the current billing cycle, and charges may continue through that cycle. Cancelling a line or account can affect promotional bill credits and device financing; remaining financed balances may become due under the applicable agreement. Porting a number to another carrier does not necessarily eliminate charges through the end of the billing cycle. Review the cancellation instructions and contact T-Mobile before making changes that could affect a promotion.
Subscription renewal information
Postpaid wireless service is billed on a recurring billing cycle. AutoPay can automatically pay eligible bills using a saved payment method, and the payment is generally scheduled about two days before the due date. AutoPay is separate from service cancellation: cancelling an account does not automatically cancel AutoPay, so review both settings when closing an account. Prepaid service and other products may have different renewal arrangements.
