Does T-Mobile sell travel eSIMs for outside of the US?
The short answer is no, but T-Mobile’s local plans can also work as international plans, as long as you have a qualifying plan with an eSIM-compatible device.
With roaming-inclusive plans, you can use high-speed data in select locations with no international data roaming charges. If you plan doesn’t include international roaming, you can get a roaming pass to keep using your phone abroad for an additional fee.
In comparison, Holafly offers a dedicated travel eSIM plan for countries or regions outside of the US.
T-Mobile roaming plans, pricing, and coverage
T-Mobile customers can use their existing eSIM to stay connected while traveling internationally. Most postpaid plans include data roaming in over 200 countries, with a set amount of high-speed data followed by unlimited data at reduced speeds. Calls and texts are also supported, though international call rates may apply depending on your destination and plan.
If you need more high-speed data while abroad, T-Mobile offers International Passes that can be added directly through the T-Mobile app. These range from 1-day to 30-day options and include premium data and unlimited calling.
