What to know about Wi-Fi Calling

Use Wi-Fi Calling
You can call, text, and use Visual Voicemail with Wi-Fi Calling.1 Just make sure you 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

Have an unlocked device? Find out if it’ll accommodate Visual Voicemail with Wi-Fi Calling (PDF, 150KB)

Turn on Wi-Fi Calling
Your phone will use Wi-Fi for calls and texts when cellular coverage isn’t available. This means that in a natural disaster or other emergency, it’ll work if connected to Wi-Fi.
  • To find out if you’re using Wi-Fi Calling, Look for AT&T Wi-Fi (Apple®) or a plus sign (+) (Android®) next to the Wi-Fi icon on your phone’s status bar. On Android phones, you’ll also see a Wi-Fi icon on the Start call and End call buttons, and on the active call status indicator.
  • Wi-Fi Calling doesn’t support calls to 211, 311, 511, and 811.
  • You can’t use Wi-Fi Calling in China, Cuba, North Korea, India, Iran, Israel, Pakistan, Saudi Arabia, Sudan, Syria, Turkey, United Arab Emirates, and Vietnam.
  • If your phone has a Keep Wi-Fi on during sleep setting, we recommend turning it on so you don’t miss calls.

Billing info

When using Wi-Fi Calling, you’ll be billed 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.
  • When you call 411 and other premium numbers, you’ll be billed at standard premium rates.
  • We bill calls to a number outside of the U.S. as an international long distance (ILD) call - even if you bought an international plan. If you’re traveling abroad, this includes calls to the country you’re in.

To avoid unexpected ILD 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.

911 calls

Placing 911 calls
When you place a 911 call, it goes over the cellular network when possible.
  • If you have to use Wi-Fi Calling to call 911, we route your call based on location data from your device and the Wi-Fi network.
  • If your Wi-Fi connection goes out during a 911 call, your call will disconnect.

Locating you when you call 911

If we can’t confirm your location, we use your Enhanced 911 (E911) address. We send your E911 info to 911 dispatchers. Keep in mind, E911 may not be as reliable as the regular 911 service.

Be sure to update the E911 address of your Wi-Fi Calling location so we can find you quickly. You can change your location info on the same screen where you turned on Wi-Fi Calling.
