AT&T first introduced Wi-Fi calling in October of 2015, allowing customers to place Calls over Wi-Fi in instances where a cellular connection is poor. At launch, AT&T's Wi-Fi Calling feature could only be used within the U.S., Puerto Rico, and the U.S. Virgin Islands, but as of this week, Wi-Fi Calls can also be made from other countries.
Starting this after**on, and following the iOS 9.3 update, AT&T began sending text messages to customers **tifying them of the change. When Traveling abroad, a call placed to the United States or received from the United States using Wi-Fi Calling will incur ** long distance charges, a feature that should be highly useful to AT&T customers who are visiting a**ther country and Calling home.
In a domestic coverage area, Wi-Fi Calling is enabled whenever wireless network coverage is weak or unavailable. When outside of a domestic coverage area, Wi-Fi Calling is **w turned on whenever a phone connects to a Wi-Fi network. AT&T's Wi-Fi calling website has been updated with new text to reflect the updated capabilities.
Use Wi-Fi Calling to talk and text over an active Wi-Fi connection. Wi-Fi Calling lets you talk and text from indoor locations where it's hard even for a strong cellular signal to reach. Wi-Fi Calling can be used in the Domestic Coverage Area (U.S., Puerto Rico, and U.S. Virgin Islands) and from most International countries.
The new International Wi-Fi Calling feature is available on the iPhone 6, 6s, 6 Plus, 6s Plus, and newly introduced iPhone SE, so long as iOS 9.3 is installed.
AT&T is also **tifying customers about a change to NumberSync, which **w allows devices linked to an iPhone to make or receive Calls over an AT&T cellular connection, something that wasn't previously possible.
The NumberSync feature allows AT&T users to make Calls and send text messages using their phone number from a device like an iPad or Mac even When their iPhone is turned off or in a**ther location. Previously, devices had to be connected to Wi-Fi to use the feature, but starting today, a cellular iPad or other device with a cellular connection can use it to make NumberSync Calls When a connected iPhone is unavailable.
