Nothing sounds worse than arriving in another country only to find out your phone doesn't work. This international roaming checklist has everything you need to know before traveling abroad. To check available options for international roaming, review International roaming services.


Your phone, coverage, and rates

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. Search each location you’ll be visiting - enter the name of the destination or country and select Check coverage. There you can review the rates and coverage map for that location.
  2. If you'll be traveling by sea, go to Going on a cruise? on that page and enter the name of your cruise ship or ferry.
  3. When you're done reviewing the coverage and rates, go to See if your device works in that country. Enter your device in the field and select SEARCH.

Additional things to know

  • Your device must register on T-Mobile's U.S. network and make a call before it can be used internationally.
  • You may need to turn on Data Roaming on your device. Choose your device in our tutorials and check out the Connections & Network section for steps.


Your charger

Don't forget to pack your 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

  • Choice plans give you up to 5GB of high-speed data in 11 European countries (Austria, Croatia, Czech Republic, Germany, Hungary, Poland, Slovakia, Macedonia, Montenegro, Romania, and Greece) at no extra charge.
  • Go5G Plus, Go5G, MAX, Plus, Magenta, ONE, and Simple Choice plans give you unlimited texting and data at up to 256kpbs in more than 215 countries and destinations at no extra charge, while voice calls are $0.25/minute. (Check calling and messaging rates.) 
  • In Mexico & Canada Go5G Plus plans give you up to 15GB of high-speed data, and Go5G plans give you up to 10GB of high-speed data.
  • To check what  plan you're on or to switch to Magenta, check out Manage your plan. or you can log in to your T-Mobile account.  


Calling while abroad

Incoming calls are routed automatically to your phone, but placing a call while you're outside the U.S. works a little differently than when you're at home. If you're on our Magenta, Simple Choice Plan, ONE Plan, or Essentials plan, voice calling is available in more than 215 countries and destinations for a flat rate of $0.25/minute.

  • To call a local number in the country you're visiting, dial the plus sign + followed by the country code, city code, and number (which can be any number of digits with or without dashes or spaces). If there's a zero (0) listed before city code, remove the zero.
  • To call back to the U.S., dial +1, the area code, and the number (Example: +1-555-123-4567). The plus sign replaces the need to use an IDD code. (It's the same to send a text message, too.)
  • You can dial 1-1-2 when traveling internationally for emergency calls. 9-1-1 may also be used in some countries in addition to 1-1-2. If you're in doubt, check the local directory or other resources for the emergency number in that country.
  • Toll-free numbers like 1-800 or 1-888 can't be guaranteed to work while abroad. Check into alternate numbers for any you may want to call while traveling.


Your voicemail password & charges

Great news, there's no extra charge for people leaving a voicemail in your inbox when you are roaming internationally. However, you will be charged for the following:

  • If your phone is on when you get an incoming call, even if you don't answer it and it goes to voicemail, the call is charged one minute for the call coming into the phone. (There are no charges at all if your phone is turned off.)
  • If you call your voicemail from your mobile phone to listen to messages, that call will be charged at the international roaming rate of the country you're in.

If you don't want to be charged for listening to your messages, you can access your voicemail from a landline or other phone. You'll need your voicemail password (the one you selected during voicemail setup). If you've forgotten your password, you can reset it by contacting T-Mobile Customer Service.

  1. From a landline or other phone, call your mobile number and have it go to voicemail.
  2. Interrupt your voicemail greeting by dialing * (the star key).
  3. When it tells you to, enter your voicemail password.
  4. Follow the menu options to check your voicemail messages.
    Note: Keep in mind, that the landline or other phone you're using may charge you long-distance fees when calling your phone to get your messages. Check into that ahead of time so you know what to expect.


Traveling on cruise ships and ferries

  • Cruise ship roaming is available on selected cruise lines and ferries.
  • To find rates while traveling at sea, visit the International Roaming page, go to Going on a cruise?, and check your Cruise/Ferry name in the box provided.
  • After reviewing the rates, navigate to See if your device is compatible and search for your device.
  • One tip to avoid higher charges: We recommend that you turn off roaming while the ship is docked in a U.S. port. Otherwise, your phone may pick up the ship's network and you'll be charged cruise ship roaming charges for any usage. Once you're out to sea, you can then turn roaming back on and pay the respective usage for data, text, and voice.
