Call and text internationally

Learn how to call and send texts to international numbers from inside the U.S. Plus, find out how to connect when traveling abroad.

What to know

Find international country codes and providers
  • Locate the country you want to call or text on the International Long Distance list. (For the best experience, view this page from a computer or tablet.)
  • The country code for calling a Mexico-based mobile number is now 52, not 521. This means you press +52, then the area code and local number. For example, +52.55.3333.6789.

Make calls and send texts
  • To a country outside of the U.S.: Press + or 011 on your phone’s keypad, then the country code and local number.
  • To the U.S. from another country: Press +1, then the area code and local number. For example, +1.212.555.3456.

Get calls and text messages
  • From the U.S., the caller can call or text your wireless number as usual.
  • From outside the U.S., the caller enters their country’s access number, and then enters 1 and your wireless number. 

Wi-Fi calling option

Traveling outside of the U.S.? No worries. You can use Wi-Fi Calling to stay connected. To use it, you must have:

  • A Wi-Fi® internet connection
  • A compatible AT&T wireless phone or AT&T PREPAID phone with Wi-Fi turned on and an eligible plan
  • An AT&T wireless or AT&T PREPAIDSM account set up for HD Voice


Billing info
When using Wi-Fi Calling, we bill you based on the number you call—no matter whether you’re using Wi-Fi® at home or while traveling abroad. This means that:

  • You can call U.S. numbers with no additional charge. Plus, it won't count as voice airtime usage.
  • We bill calls to a number outside of the U.S. as an international long distance call – even if you bought an international plan. If you’re traveling abroad, this includes calls to the country you’re in.
  • When you call 411 and other premium numbers, we bill you at standard premium rates.


Heads up: Starting November 1, 2021, AT&T 411 Directory Assistance won't be available on your wireless device.

To avoid unexpected international long distance charges when outside of the U.S., use Wi-Fi Calling only for calls to the U.S. Be sure to turn off Wi-Fi Calling for all other calls if you have an international talk, text, and data plan.

International customer service info

  • From inside the U.S.: Call 800.335.4685 (or 611 from your AT&T wireless phone).
  • From outside the U.S.: Call anytime. It's a free call from your AT&T wireless phone.
