International roaming checklist

    Nothing's worse than traveling to another country only to find your phone doesn't work there. Our international roaming checklist makes sure you have everything you need when traveling abroad.


    For more information about available roaming services, see International roaming services.


    Your phone

    We want you to be able to step off the plane and use your phone without costly roaming fees. Here's how to check whether your phone is ready and if there'll be any additional costs:


    1. Tell us which country you’ll be visiting by entering it in the look-up tool and clicking CHECK RATES & COVERAGE. You can review the rates and coverage map for that country. If you'll be traveling by sea, click Going on a cruise? Check out your rates on cruises and ferries below the country search tool.
    2. When you're done reviewing the coverage and rates, scroll down to See if your device works in that country. Enter your device in the field and click SEARCH.



    Your phone's charger

    Don't forget to pack your power cord/charger and invest in a travel adapter and electrical converter. Most countries outside the U.S. and Canada have different types of outlet plug designs.



    Your plan

    If you're on our Simple Choice Plan or T-Mobile ONE, you get unlimited data and texting in more than 140 countries at no extra charge. To check which plan you're on, log in to My T-Mobile. If you need to, learn how to Change your plan.
