If you are a T-Mobile customer, the cost of T-Mobile international calling costs depends on whether you are traveling abroad or calling from the U.S. While roaming in 215+ countries, voice calls are billed at a flat $0.50 per minute for both making and receiving calls, though Wi-Fi calls to the U.S., Mexico, and Canada are free.
What are T-Mobile international calling costs while traveling?
When you travel internationally to any of T-Mobile's 215+ covered countries and destinations, every voice call you make or receive costs $0.50 per minute. This rate applies automatically on most plans and covers both outgoing and incoming calls. However, if you connect to Wi-Fi in those same 215+ countries, calls back to the U.S., Mexico, and Canada are free, no per-minute charge applies. This makes Wi-Fi calling the most affordable way to stay in touch with those three destinations while roaming.
T-Mobile international passes with unlimited calling
For travelers who want unlimited calling and faster data, T-Mobile offers International Passes. These passes include unlimited voice calls and a set amount of high-speed data. The 1-Day Pass costs $10 and includes 2GB of high-speed data. The 10-Day Pass costs $50 and provides 15GB of high-speed data. The 30-Day Pass costs $75 and gives you 30GB of high-speed data. All passes include unlimited calling, so you never have to worry about per-minute charges during the pass period. International Passes can be purchased through the T-Mobile website, not just the T-Life app. To buy a pass, use the T-Life app or log into your account on the T-Mobile website. If you need to activate T-Mobile international pass, the purchase process on either platform immediately applies it to your line.
How much does it cost to call internationally from the U.S.?
Calling international numbers while you are physically in the United States is a different story. Most T-Mobile plans include free unlimited calling to Mexico and Canada, so those calls cost nothing extra. For calls to other countries, T-Mobile offers the Stateside International Talk add-on for $15 per month per line. This add-on gives you unlimited calling from the U.S. (and from Canada and Mexico on qualifying plans) to landlines in 70+ countries and mobile lines in 30+ countries. The Stateside International Talk add-on provides discounted rates to other destinations not covered by the unlimited calling. A limited-time account-wide offer lets postpaid customers add Stateside International for $20 per month covering all lines on the account, a good value if multiple family members make frequent international calls. A limited-time offer allows T-Mobile postpaid customers to add an account-wide 'Stateside International' add-on for $20 per month, covering all lines. When evaluating international calling and plans on carriers, T-Mobile's add-on approach is straightforward for regular callers from the U.S.
How to dial an international number on T-Mobile
Dialing an international number from the U.S. on T-Mobile requires a specific format. Follow these steps:
- Press and hold the 0 key until the plus sign (+) appears on your screen.
- Enter the country code for the destination (e.g., 44 for the UK, 81 for Japan).
- Enter the full phone number, including the area code, omitting any leading zero that the country may use for domestic dialing.
- Press the call button.
When calling certain international numbers, T-Mobile may play an automated message asking you to enter a random two-digit number between 10 and 99. This is a fraud-prevention measure designed to verify that a person, not an automated system, is placing the call. Simply enter the two digits you hear to complete the call.
Countries and destinations not covered
Not every destination is included in T-Mobile's standard rates or International Passes. Some countries and destinations are excluded from standard plan benefits and from International Pass coverage entirely. In those locations, calls, texts, and data are charged at country-specific rates that can be higher than the standard $0.50 per minute. Before traveling, check the list of the 210 countries covered by T-Mobile to confirm your destination qualifies for standard roaming or pass usage. If your destination is excluded, you may need to use Wi-Fi calling or a local SIM to avoid surprise charges.
Frequently Asked Questions
Does the $0.50 per minute rate apply to calls made on a cruise ship?
No. Cruise ship calls are routed through the ship's maritime network, which is not part of T-Mobile's 215+ covered countries. Those calls are charged at separate maritime rates, which are typically much higher than $0.50 per minute.
Can I use an International Pass while already roaming without a pass?
Yes. You can purchase an International Pass at any time while traveling abroad through the T-Life app or your T-Mobile account. The pass takes effect immediately and covers calls and data from the moment of purchase.
Does Stateside International Talk cover calls to mobile phones in all 70+ countries?
No. The add-on covers unlimited calling to landlines in 70+ countries and to mobile lines in 30+ countries. Calls to mobile numbers in countries not on the mobile list are billed at discounted per-minute rates rather than being unlimited.
Are international calls made over Wi-Fi from the U.S. free?
Yes. Wi-Fi calls from the U.S. to any international number are treated like domestic calls for billing purposes. If your plan includes unlimited domestic calling, those international Wi-Fi calls are free, no per-minute charge applies.
What happens if I exceed the high-speed data on an International Pass?
Once you use all the high-speed data included in your pass, your data speed is reduced to 2G/3G speeds for the remainder of the pass period. Unlimited calling and texting continue to work normally at full quality.
