American mobile operator T-Mobile is set to test an AI feature that translates phone conversations in real-time into more than 50 languages, according to The Verge.
The beta testing of the Live Translation service will commence in spring 2026. The company has already opened pre-registration for users.
“Some of the biggest barriers mobile users face are the simplest, like the ability to understand each other. By integrating artificial intelligence into our network, we offer more than just connectivity,” said T-Mobile CEO Shrinivas Gopalan.
No special apps or devices are required to use the service. The only requirement is that a T-Mobile subscriber must initiate the translation.
The feature will be available on the 5G Advanced and 4G LTE networks.
“The key requirement is a Voice over LTE (VoLTE) connection, which allows the service to work reliably across a wide range of devices and network conditions,” said T-Mobile President John Saw.
The feature supports VoLTE, VoNR, and VoWiFi standards, making it accessible to a broad range of users regardless of network type.
Beta test participants will be able to activate Live Translation for free and without time limits. Initially, users need to call 87, but future updates will include support for the voice command Hey T-Mobile.
The service operates during active calls and does not store audio recordings or text transcriptions of conversations.
“It is designed for real-time translation and then shuts down without saving call content,” emphasized Saw.
Back in March 2025, Europe’s largest telecommunications company Deutsche Telekom announced an AI smartphone based on the Perplexity chatbot.
