If you are a subscriber of AT&T and own an iPhone 6 device (or newer model), you can now make and take voice calls by way of Wi-Fi outside the country. Yup, the second biggest wireless carrier in the United States has started sending text messages to its subscribers just this week, basically notifying them that AT&T’s Wi-Fi calling feature has been expanded to territories outside the US. As updated in the official web page for AT&T’s Wi-Fi calling service, the feature can now be used in the Domestic Coverage Area (which includes the US, Puerto Rico, and the US Virgin Islands) as well as from most international regions. Before, the service was only made available in the US, Puerto Rico, and the US Virgin Islands. But with this latest development, subscribers of AT&T can now receive phone calls via Wi-Fi when traveling to other countries.
For those not familiar with Wi-Fi calling, it is basically a wireless service that allows the mobile user’s smartphone to use an existing Wi-Fi network when making or taking voice calls. This feature can come in handy whenever a user finds himself in a location where the cellular network is either spotty or non-existent at all. Because the service is typically provided directly by the wireless carrier and the user’s smartphone, there is no need to download any third party mobile app in order to take full advantage of Wi-Fi calling. To date, the Big Four wireless carriers in America (Verizon Wireless, AT&T, T-Mobile, and Sprint) all offer Wi-Fi calling services.
For mobile users, making use of Wi-Fi calling has its advantages. Firstly, they can cut on costs. Making a phone call to somebody by way of a Wi-Fi network from a US based phone number to another US based phone number will not incur any extra fees when abroad. And although calling an international phone number using a US based phone number will incur standard international calling charges, mobile users will not be charged airtime fees. Plus, users can send text messages through Wi-Fi, too.
But it should be noted that AT&T’s Wi-Fi calling service is not perfect. For one, only those AT&T subscribers who own an iPhone 6, iPhone 6 Plus, iPhone 6s, or iPhone 6s Plus get to use the feature. On top of that, mobile users must also install iOS 9.3, the latest version of Apple’s iOS mobile operating system. The good news is that the iPhone maker has just started rolling out the update this week.
