Tomorrow, some T-Mobile customers are going to receive a final reminder directly from the carrier. These are customers who still use 2G handsets, and they will be reminded that on August 3, T-Mobile will start shutting down its 2G GSM network.
T-Mobile kept its 2G network running longer than its competitors
The carrier has been sending notices to its customers for over two years and has been offering these subscribers a free select 5G phone. The letter reminds these customers to head out and visit a T-Mobile store to get their current 2G phone upgraded.

You might be angry with T-Mobile for pushing you off your 2G lifestyle, but the carrier kept its 2G network running for longer than its rival networks. For example, AT&T shut down its 2G network on January 1, 2017, and Verizon closed its legacy 2G and 3G CDMA networks December 31, 2022. That was three years after Verizon had originally planned to turn off its 2G and 3G service.
T-Mobile left its 2G network up to help international roaming customers stay connected
T-Mobile says that it waited as long as it did to fill the gap left by the 2G departures of AT&T and Verizon. It also wanted to make sure that international visitors to the US were arriving to American shores without connectivity for their 2G phones. That's because some international roaming customers, whose home wireless provider did not have them enabled for VoLTE, used 2G service for their voice calls dropping back from LTE.
Which of the US "Big 3" carriers is the most innovative right now?
For more than two and a half years, T-Mobile worked with most global wireless providers to deliver VoLTE service to make sure that everyone has voice and data service. But now T-Mobile says that it is ready to "retire the 2G network and keep advancing the country's largest and fastest 5G network."
Moving customers who are on old networks onto modern, advanced high-speed networks like 5G 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 regularly send notifications and customers who need to take action will receive advanced notice.

Speaking about international roaming, T-Mobile's Live Translation, available on its 5G network, is an AI-powered feature that delivers real-time translation during conversations without requiring a separate installed app or a phone upgrade.
T-Mobile's 5G Advanced service relies on its standalone 5G network. Using the latter, T-Mobile can offer customized network slicing, six-way carrier aggregation and lower latency.
Transitioning subscribers get to experience the speed of 5G connectivity
To help smooth the transition from 2G to 5G, T-Mobile points out that its transitioning customers will get faster speeds and more reliable coverage with its 5G network. New features such as T-Satellite are available to those on compatible devices and plans. With T-Satellite, whenever customers finds themselves in a dead zone with no cellular service or Wi-Fi, they can use T-Satellite and take their connectivity to the sky.
T-Mobile's 5G customers are also safer as the carrier uses its 911 location accuracy capabilities. Additionally, T-Mobile is already investing its cash in AI-RAN and 6G-ready infrastructure. These are network components that can handle the demands of the upcoming 6G networks such as fiber-optic backbones, cloud-native software, and edge computing data centers.
In case you are curious, Sprint retired its old 3G CDMA network on March 31, 2022. On June 30, 2022, Sprint turned off its LTE network. The very next day, T-Mobile shut down its older 3G UMTS network.
How to contact T-Mobile if you have any questions
