What To Do If Your T-Mobile Discount Code Isn’t Working

Savings are Cyclical at T-Mobile

T-Mobile offers deals and promotions throughout the year. But there are certain times when it tends to have the best deals, and it is quite predictable. So if you want to get the most savings, these are the major annual events to wait for:

  • Black Friday and Cyber Monday: T-Mobile typically offers some of their best deals during the Black Friday and Cyber Monday shopping events. Promotions may include discounts on phones, plans, and accessories.
  • Holidays: T-Mobile often offers promotions and discounts during the holiday season, which includes Thanksgiving, Christmas, and New Year's. During these holidays, you can capture discounts on phones, free lines, or credits for accessories.
  • New device launches: T-Mobile tends to offer deals and promotions when new devices are launched. For example, when a new iPhone is released, T-Mobile may offer discounts on the device or credits towards accessories. Additionally, older models will also see big markdowns.

Bring in Friends and Family for More Discounts on a Plan

While T-Mobile’s unlimited plans offer several benefits, they are still somewhat costly as a solo line. The best way to bring your individual costs down is to add lines to your plan. With 4 lines on a Magenta plan, you are only paying $35 per line versus $70 if you were alone. That's a savings of 50%. So help your friends and family switch to T-Mobile to enjoy the most savings on your cell phone plan.

Great T-Mobile Deals and Discounts

  • Discover impressive offers and discounts on the T-Mobile Deals page. The Deals link is on the top of the T-Mobile homepage.
  • Sign up for the Magenta Military plan and get a discount as a service member. The verification steps are listed on the Military & Vets page. This link is under Prices & Plans on the lower portion of the home page.
  • A discounted plan is available for First Responders at T-Mobile. Verify at activation to start saving 50% on family lines.
  • T-Mobile offers senior citizens a discounted plan called the Unlimited Essentials 55+. Get two lines with 5G access for $27.50 each and other great benefits.
  • Manage your T-Mobile bill effectively every month using the billing meter. This tool compiles information about your bill each month, so you can easily track exactly when the charges increase or decrease. You can access the bill meter on the My T-Mobile page.
  • Use your old phone to activate T-Mobile savings. If you trade in your phone, you'll get bill credits. To get a credit estimate, click the Trade-in Program link; it's located under the Switch to T-Mobile column on the bottom of the page.
  • Save by activating T-Mobile's service on your cell phone if it's compatible. To check the compatibility, hover over the Phones & Devices section on the top of the T-Mobile page, and click the Bring Your Own Device link.

Sprint and T-Mobile

On August 2, 2020, the Sprint brand was officially discontinued under the T-Mobile umbrella. On that date, everyone who was still under Sprint branding transitioned to T-Mobile branding.

T-Mobile Free Shipping

To see what shipping deals are available, move your mouse over the Deals section, click on a phone brand, and turn on Special Offers. This strategy will help you pinpoint phones that include free shipping.
