Before you travel, use T-Mobile’s International Roaming checker to check your destination and phone, then confirm the roaming benefits for the exact plan on your account. A country’s inclusion does not guarantee service everywhere, and data, calling, and charges vary by plan and destination.
Check coverage and compatibility for your destination
-
Open T-Mobile’s International Roaming page.
-
Enter your destination. The checker allows up to three destinations, so include every country on your itinerary.
-
Select the phone or other device you plan to use, then choose Check coverage. Sign in if prompted for personalized coverage information.
-
Review the result for both international coverage and device compatibility. Treat it as destination-specific guidance, not a guarantee of signal at every location: T-Mobile says some areas have no coverage, and a capable device and qualifying postpaid plan are required for the described benefits.

Confirm what your plan includes
Check the plan on the specific line you will use, through your T-Mobile account or app, and compare its benefits with the checker’s destination result. T-Mobile separates Canada and Mexico, its 215+ covered countries and destinations, and places without standard plan benefits or International Pass coverage. The 215+ figure is T-Mobile’s description of its service footprint, not an independently verified count.
Data allowances are plan-specific. Some plans include a set amount of high-speed roaming data and then continue at reduced speed; do not assume an allowance listed for another plan or plan version applies to your line. Verify the allowance and what happens when it runs out in your account before using roaming data for navigation, video, or other high-data activities.

Check the destination’s charges and pass eligibility
Review the current destination rate details on T-Mobile’s International Plans page before departure. T-Mobile currently lists texts as included in its 215+ covered destinations and calls while roaming there at $0.50 per minute. That per-minute rate applies to the covered group; do not apply it to a country listed as pay-per-use or otherwise excluded. Canada, Mexico, and plan-specific data benefits differ.
T-Mobile says more than 20 countries and destinations do not have rate-plan roaming benefits or International Pass coverage. Calls, texts, and data in those places are charged at country-specific rates, which can change. Look up the exact country in T-Mobile’s current destination information; if the postpaid rate is not shown clearly, contact T-Mobile rather than estimating from another country’s rate or from prepaid pricing. T-Mobile’s international roaming services support page is the carrier’s linked country-by-country reference.

Use the separate checker for cruise travel
For a cruise, use T-Mobile’s cruise coverage information rather than relying only on the country checker. A phone can connect to a ship’s network even while the vessel is docked in a U.S. port, potentially triggering cruise charges. T-Mobile advises turning roaming off while docked in a U.S. port. Once at sea, you can turn it back on, but voice, text, and data use may be charged under the ship-network terms.
Keep extended roaming and service limits in mind
T-Mobile says international roaming is not intended for extended use abroad. Its terms require U.S. residence and primary usage on its network, and the carrier may restrict service for excessive roaming. A short trip check cannot determine whether a prolonged stay will comply with those requirements, so review the current terms for your plan if you expect to spend a substantial period outside the United States.
