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. T-Mobile has the largest and fastest 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 have retired older network technologies as part of an important progression to ensure all customers can enjoy a more advanced 4G and 5G network. This page provides information on T-Mobile’s efforts to retire these older technologies and help transition customers.

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. We’ll ensure that we support our customers and partners through the transition. We began sending notifications in late 2021 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 can be many times faster
  • Enhanced public safety and 911 location accuracy capabilities that will make customers safer

Key Dates

  • While we have not yet established an exact date, we will notify you in advance when we plan to retire T-Mobile's older 2G (GSM) network. Please be aware that as we work towards this retirement, capacity and coverage of the T-Mobile 2G (GSM) network will change as some 2G (GSM) sites will come down prior to the full network retirement.
  • As of July 1, 2022, T-Mobile’s older 3G UMTS network has been retired
  • As of June 30, 2022, Sprint’s LTE network has been retired
  • As of March 31, 2022, Sprint’s older 3G (CDMA) network has been retired
