How Do I Call & Text While Abroad?

Dialing Numbers While Abroad Works Differently:

  • To call back to the U.S., dial +1, the area code, and the number (Example: +1-555-123-4567).
  • To call a local number in the country you're visiting, dial the plus sign (+), followed by the country code, city code and then the phone number. The phone number can be any number of digits, with or without dashes or spaces. If there's a zero (0) listed before the city code, remove the zero. Here’s a helpful list of country codes that you can reference prior to your travels.

Other Tips When Dialing Abroad:

  • You can dial 1-1-2 when traveling internationally for emergency calls. 9-1-1 may also be used in some destinations 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 might not work while abroad. Check for alternate numbers for any you may want to call while traveling.

Checking Your Voicemail While Abroad:

  • Great news, there's no extra charge for utilizing voicemail while you're traveling internationally.

What Other Ways Can I Stay Connected?

What if I travel to a destination that is not covered by Global Roaming?

How Can I Troubleshoot On My Own?

We have a few last tips and troubleshooting steps for you, as helpful reminders. Of course, if you’re still experiencing issues, our customer care agents are here to help at the number below.

Texting issues:

  • If you are using iOS on an iPhone, it’s possible that iMessage could be switched off, which means texting over Wi-fi will not function properly. To remedy, search for iMessage on your device and make sure the iMessage toggle is green.

Wi-Fi calling or data issues:

  • It’s possible that the Wi-Fi on your device is turned off, in which case you’ll want to turn it back on in settings to connect to nearby Wi-Fi networks and use features like Wi-Fi calling.

Other tips:

  • As a final tip, some issues can be resolved by resetting your device. Reset procedures vary widely by device and operating system; we recommend becoming familiar with this process before your travels.
