This marks a small yet important change to how users can benefit from Wi-Fi Calling. Up until now, Wi-Fi calling for AT&T customers restricted them to using the service only from the U.S., Puerto Rico, or U.S. Virgin Islands. But now, it is opened to any country (except for a few exceptions), meaning an AT&T Wi-Fi Calling user can make calls to the US, or receive calls from the US anywhere in the world as long as there is a Wi-Fi connection.
Message I got:
With the latest software update for your phone you can use Wi-Fi Calling when traveling outside the U.S. This means you can call back to the U.S. or receive incoming calls, with no airtime charges. When you call international numbers, your rates will be the same as those in your smartphone plan or your international package. For details visit att.com/wificalling
So, now when you are travelling abroad and are in an area with poor network reception, you can use Wi-Fi calling to call back your friends and family in the United States for free. If you end up calling a non-U.S. number, you will be charged as per AT&T’s international call charge rates.
AT&T has also updated its website to reflect this change, and it clearly mentions that iPhone 6, 6s, 6 Plus and the iPhone 6s Plus support this feature provided they run on iOS 9.3. AT&T is also pushing a new carrier update to iPhones to enable this feature, so make sure you have it installed as well.
Additionally, using NumberSync AT&T will now also you to receive or make calls over its data network from other devices that are linked to your iPhone and account, even if the latter is switched off or in a different location.
