Compatible smartphone and voice plan required.

Wi-Fi Calling lets you talk and text over an active Wi-Fi connection. You can turn Wi-Fi Calling on or off in your phone&rsquo;s settings. With Wi-Fi Calling, you can call, text, and use AT&amp;T Visual Voicemail as you do on the cellular network.

While in the U.S., AT&amp;T Wi-Fi Calling is used when a cellular signal is weak or unavailable.

While traveling in many countries outside the U.S., your phone will automatically use the Wi-Fi network instead of a mobile network when both are available. (AT&amp;T Wi-Fi Calling is restricted in some countries.)

Calls are billed based on the number you call when in the Domestic Coverage Area (U.S., Puerto Rico, and U.S. Virgin Islands.) 
&bull; Calls to U.S. numbers can be made at no additional charge 
&bull; Calls to premium numbers like 411 are billed at standard premium rates 
&bull; Calls to international numbers from the U.S. are billed at your&nbsp;<a aria-label="international long-distance rates" href="/shop/en/wireless/international/long-distance.html" rel="noopener" tabindex="0" target="_self">international long-distance rates</a> 
 
If you&rsquo;re traveling abroad 
&bull; Calls to U.S. numbers can be made at no additional charge 
&bull; Calls to international numbers are billed based on your&nbsp;<a aria-label="international roaming package" href="/international/" rel="noopener" tabindex="0" target="_self">international roaming package</a>

Most of the Apple and Android smartphones we have sold since 2015 support AT&amp;T Wi-Fi Calling. You&rsquo;ll still need a smartphone with an eligible rate plan for it to work.

No. Wi-Fi Calling will not support calls over TTY devices, including 911 calls. To reach 911 service, persons with communications disabilities may do one of these:

1. Call 911 directly using a TTY from a wireless phone over the cellular network or from a landline telephone. 
2. Send a text message to 911 directly (in areas where text-to-911 is available) from a wireless device. 
3. Use relay services to place a TTY or captioned telephone service (CTS) call from a wireless phone over the cellular network or from a landline telephone. 
4. Use relay services to place an IP Relay or IP CTS call over a cellular data or other IP network.

View RTT progress can use&nbsp;<a aria-label="real-time text" href="/support/article/wireless/KM1233824/" rel="noopener" tabindex="0" target="_self">real-time text</a>&nbsp;as an alternative to TTY. 911 services can be reached by either.

You can use Wi-Fi Calling with just about any Wi-Fi internet connection. For it to work, the Wi-Fi Calling setting on your device needs to be turned on and you must be connected to a Wi-Fi internet network.

You can use it in our Domestic Coverage Area (U.S., Puerto Rico, U.S. Virgin Islands), and from most international countries. While traveling in many countries outside the U.S., your phone will automatically use the Wi-Fi network instead of a mobile network when both are available.

Wi-Fi Calling is restricted in the following countries: China, Saudi Arabia, India, Turkey, Israel, United Arab Emirates, Vietnam, Pakistan, Cuba, Iran, North Korea, Sudan, and Syria.

Once enabled, Wi-Fi Calling works automatically.

iPhone:&nbsp;The word &ldquo;AT&amp;T Wi-Fi&rdquo; will appear next to the standard Wi-Fi icon in the status bar.

Android:&nbsp;A plus (+) sign will appear next to the standard Wi-Fi icon in the status bar. You will also see a Wi-Fi icon on the start and end call buttons as well as on the active call status indicator.

If you are using Wi-Fi Calling in the Domestic Coverage Area and HD Voice coverage is available, your call will attempt to switch to cellular and continue without a break when your Wi-Fi connection is lost. This does not apply to 911 calls.

If your Wi-Fi connection is lost, your call will drop in these cases: 
&bull; You are not in HD Voice coverage (for example, in 3G or 4G coverage) 
&bull; Your device is in airplane mode 
&bull; You are making a 911 call 
&bull; You are traveling outside the Domestic Coverage Area

Yes. When you place a 911 call, the call will go over the cellular network when possible. If no cellular network is available, device location data from nearby Wi-Fi networks will be used to help locate you. If that data isn&rsquo;t available, the address you provide will be used. The address must be located in the Domestic Coverage Area and cannot be a P.O. Box. We recommend that you update the address of your current location whenever you use Wi-Fi Calling.
