T-Mobile is rolling out a beta of Live Translation, a real-time call translation feature embedded in the network that supports over 50 languages without any extra apps or equipment.

During calls, any T-Mobile subscriber can activate the AI agent by dialing star-eight-seven-star, or later by saying 'Hey T-Mobile,' with no user setup or prior language selection required.

This live translation marks the first customer-facing AI agent in T-Mobile’s network strategy, signaling a broader move toward AI-enabled network services, with potential future uses like an AI receptionist or concierge.

The article does not disclose pricing details for the general public post-beta or broader availability.

The beta is free during testing, with a broader commercial launch planned for later in 2026 after iterative testing and refinements.

Eligible postpaid customers can register starting February 11 to participate in the beta, with testing slated to begin in the spring and spots limited.

T-Mobile asserts translations meet FCC captioning guidelines and ADA accessibility standards, stating calls are not trained on customer data or listened to, though internal testing is used for fine-tuning.

The beta is designed to gradually test the service before a commercial rollout, and users will be notified when the beta ends and given the option to add Live Translation to their line.

Beta rollout is planned for this spring and will operate on both 5G and 4G LTE networks.

Sponsor content surrounding the announcement is acknowledged, but the core news is the Live Translation feature itself.

The service translates in real time and does not store call recordings or transcripts, addressing privacy by not retaining call content after translation.

T-Mobile notes the relevance of real-time translation given 6 billion international calls annually and 40% of customers traveling internationally, aiming to remove barriers to international communication.
