Since Sprint and T-Mobile merged, we’ve worked to combine Sprint’s assets with T-Mobile’s to deliver a transformative 5G network experience from big cities to small towns and places in between. Now T-Mobile has the largest, fastest, and most reliable 5G network according to data from third-party benchmarking companies. On top of that, T-Mobile’s 4G LTE network covers 99% of Americans. Learn more about our 5G network.

Across the industry, wireless companies are working to retire older network technologies as part of an important progression that will greatly enhance the performance of 4G and 5G, giving customers a better wireless experience. This page provides information on T-Mobile’s efforts to retire these older technologies and help transition customers.

To ensure all customers can enjoy a more advanced 4G and 5G network, we will be retiring older network technologies to free up resources and spectrum that will help us strengthen our entire network, move all customers to more advanced technologies and bridge the Digital Divide. An additional part of this effort involves moving Sprint’s LTE spectrum to the T-Mobile network.

Moving customers who are on old networks onto modern, advanced high-speed networks means they will need to have phones and devices that can tap into the latest technologies and don’t rely on older ones. We’ll ensure that we support our customers and partners through the transition. We began sending notifications late last year, and everyone who needs to act will be given advanced notice and hear directly from T-Mobile. 

Customers who move from older technologies to 4G/5G service will get:

  • Real broadband speeds that are can be many times faster
  • Enhanced public safety and 911 location accuracy capabilities that will make customers safer
