AT&T is now allowing its subscribers to use Wi-Fi calling while they are travelling abroad, with the carrier sending out text messages to eligible customers to let them know.

Users who have upgraded their iPhones to iOS 9.3 will be able to utilize Wi-Fi Calling while in other countries, so that they will not be accruing any additional charges.

With the announcement, AT&T subscribers abroad will no longer have to resort to international minutes and plans to make calls back home, as these calls will be charged with the same rates as if they are calling from within the United States.

The availability to use Wi-Fi Calling in international countries was confirmed by AT&T through its dedicated page for the feature on its official website.

The page explains that Wi-Fi Calling can be used to make calls and send text messages through Wi-Fi connections instead of cellular connections. Once the feature is activated on the iPhone, it works automatically, with Wi-Fi Calling connecting whenever the user experiences weak or unavailable wireless network coverage.

For international locations, Wi-Fi Calling will activate whenever the user connects the iPhone to a Wi-Fi network, though AT&T noted that the feature could have restrictions in certain countries.

The devices that support Wi-Fi Calling are the iPhone 6s, the iPhone 6s Plus, the iPhone 6 and the iPhone 6 Plus. Subscribers do not have to install any app to activate the feature, as it is built into the device.

AT&T launched Wi-Fi Calling in October of last year, just days after receiving the necessary permits from the FCC. T-Mobile and Sprint had already been offering the feature despite not possessing any permit, which AT&T waited to receive approval for before pushing out the feature to its subscribers.
