When you travel outside of T‑Mobile’s network areas, your phone automatically switches to use one of our wireless network partners when coverage is available, you have data roaming enabled, and you have roaming data remaining. Speeds and connections may vary. Most plans allow data roaming. See details about domestic roaming data. Not available for prepaid tablet and wearable plans.

If you joined us before 7/15/15, update your plan to get this coverage. Check your plan for international roaming details.

We’re constantly working to improve our network, but some areas may have no coverage due to inaccessible landscape, physical barriers, or places where our towers can’t reach. But don’t worry – you can use your phone to make calls and text anywhere there’s Wi-Fi. Just connect your phone to a Wi-Fi network and it’s all set.
