T-Mobile Switches on eSIM for Easy Switching

T-Mobile has updated its main T-Mobile app to enable customers of other carriers to switch to T-Mobile "in as little as a few minutes." The feature is able to activate the phone on a new T-Mobile line from right within the app, using eSIM technology. eSIM is found in recent Apple iPhones, Google Pixels, and many recent Samsung phones. Optionally, users can use this feature to activate a free three-month trial of T-Mobile's network as a second line, while keeping their existing service on the phone's primary SIM card. The feature is available for both consumer and business customers. The updated T-Mobile app is available now for iOS, and coming soon for Android.
