When to Shop at T-Mobile

T-Mobile runs promotions on Black Friday, during holidays and back-to-school season, and during major product launches. These deals help you save big on smartphones, tech accessories, and service plans year-round. To get the deepest discounts, make sure to shop T-Mobile's Black Friday event.

T-Mobile Black Friday Sale

During Black Friday, T-Mobile offers major discounts on devices, accessories, and service plans. Discounts usually drop the week before the big day and include free shipping for online shoppers. In the past, we’ve seen offers for free iPhones, Samsung Galaxy phones, and Google Pixel phones with trade-in on Go5G Next plans. We’ve also seen special promotions for Metro by T-Mobile users.

T-Mobile Cyber Monday Savings

Cyber Monday at T-Mobile offers extensions on Black Friday discounts.

T-Mobile Holiday Deals

During the holidays, T-Mobile usually offers big savings for switching carriers, adding new phone lines, or buying new smartphones and accessories. You’re also likely to see Metro by T-Mobile deals, device-specific offers, and monthly bill credits. Last year, we saw offers for a free iPhone or Samsung Galaxy S25 with no trade-in when adding new lines. Deals typically extend from December into the New Year.

T-Mobile Back-to-School Deals

Every June or July, T-Mobile runs special back-to-school deals on devices and services. In 2024, they offered a free select smartphone when adding a new line, an iPhone 16 with trade-in, and $300 back on 5G Home Internet. They also spotlight Project 10Million, which provides 200 GB of free high-speed data to eligible households. Deals usually extend through August.

T-Mobile-Exclusive Launch Offers

When Apple, Google, and Samsung release new devices, T-Mobile often has exclusive launch offers that offer big savings and perks. These "On Us" deals often feature a free smartphone with trade-in or a new line. Look for bundles with accessories like Pixel earbuds and Apple watches, switching incentives, and more. Past deals included the "4 Lines for $100" family plan and up to $600 off Pixel 9 devices with a new line.

T-Mobile ID Signup

Want to be in the know on the latest T-Mobile discounts and releases? Create a T-Mobile ID with your email and phone number to manage your account from anywhere and receive helpful updates. There is no dedicated T-Mobile newsletter with online coupons for standard users. Metro by T-Mobile customers join an email list that gives access to special offers and early notice on new phones, products, and services.

T-Mobile Educational Discounts

If you're a student or educator, you get discounts on devices and plans through T-Mobile for Education. Educators also save 15% on eligible plans, devices, and accessories through the Work Perks program.

T-Mobile Deals for First Responders, Military, and Veterans

Are you a first responder, military member, or veteran? T-Mobile honors your service with up to 40% off or $720/year savings on Experience plans. To redeem, just use your .mil email or professional ID to verify your status directly at T-Mobile.
