T-Mobile provides voice and data services for phones and other mobile devices in the U.S. and elsewhere. The company's T-Mobile ONE basic plan for phones, which replaced the company's previous plans, includes unlimited talk, text, and data throughout North America, including Mexico and Canada.

T-Mobile partners with other wireless carriers in areas where T-Mobile doesn't offer service. When you use your phone in one of those areas, you are roaming.

There are no roaming charges for calls or data usage in these areas, but your plan has a roaming limit. 

How Domestic Data Roaming Works

If you have T-Mobile ONE or the most recent Simple Choice plan, your roaming limit is 200MB of domestic data per month. You pay no roaming fees, but when you reach your domestic data roaming limit, access to data while roaming is turned off until you return to an area with T-Mobile coverage or until the beginning of your next billing period. You also have the option to purchase an additional one-day 10MB or seven-day 50MB domestic roaming data pass. 

T-Mobile sends an alert when you reach 80 percent of your monthly domestic data roaming allotment. You receive another alert when you reach 100 percent. You can also view your usage on the T-Mobile app on your device.

Wherever you are—roaming or not—you can always connect to data using a Wi-Fi signal.

Tips to Reduce Data Usage While Roaming

To reduce your data usage when you are roaming:

  • Use Wi-Fi whenever it is available, especially when you are streaming content or downloading.
  • Turn off automatic synchronization on your email and social networking apps.
  • Disable data roaming entirely on your device.
  • Monitor your data usage through the T-Mobile app.
