Dialing international numbers can be trickier than remembering your parent's Wi-Fi password, but we're got you covered. Read below to find out all you need to know.
- The easiest way to make an international call, including to and from the US, is to dial the + (which should be the same key as the 0), followed by the country code, and then the phone number.
- The + replaces the International Direct Dialing (IDD) code when you use a mobile phone to make a call to another country.
- Before you dial, be sure to check out our International calling services and rates.
Call a country outside the U.S.
Dial "+" followed by the country code, city code (if necessary), and local number. This works the same regardless of if you are calling from the U.S. or if you are traveling in another country.
Call back to the U.S. from another country
Dial +1, the area code, and the number (example: +1-555-123-4567).
Call Mexico from the U.S.
- Mobile numbers: Dial + > Dial 52 > Dial 1 > Dial the ten-digit mobile number. (some mobile numbers may require the two or three digit area code after the '1')
- Landline numbers: Dial + > Dial 52 > Dial the two or three digit area code > Dial the 7 or 8 digit number.
Call toll-free numbers while you are outside the U.S.
Toll-free numbers such as 1-800 or 1-888 cannot be guaranteed to work while abroad. Be sure to look up alternate numbers before you take your trip.
Call T-Mobile Customer Service while you are outside the U.S.
From your mobile device, dial the plus sign + followed by 1-505-998-3793. We won't charge you anything for this call, no matter where you are. Go ahead and store this number in your phone's contact list for easy and quick dialing while you're away.
|Location||IDD||Country Code||City or Mobile Code||Phone Number*||Full Number Dialed*|
|Seattle, WA USA||+||1||206||XXX-XXXX||+1-206-XXX-XXXX|
|Mexico City, Mexico||+||52||55||XXX-XXXX||+52-55-XXX-XXXX|
*Please note, XXX-XXXX is just a placeholder. Phone numbers can vary in length from 2-13 digits based on the dialing patterns and city or mobile code in each country.
- When calling some countries, you may hear an automated message that gives you a random two-digit number between 10 and 99 that you must enter in order to complete the call.
- T-Mobile added this extra step to help prevent fraud, and it's only needed when calling certain international locations.
