However if you are an AT&T user and international WiFi calling on your iPhone is a feature you’ve been longing for, you’re in luck. According to reports, it seems that the update to iOS 9.3 has enabled international WiFi calling on AT&T iPhones. Customers have started receiving text messages from the carrier notifying them of the change.
According to the message, “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.”
Just in case the name wasn’t already obvious, WiFi calling allows users to place calls over WiFi. By enabling it internationally, users can make calls back home to the US without incurring roaming charges, as long as they are on WiFi. We suppose there are apps like WhatsApp, Skype, and Viber that kind of do the same thing, but if for some reason you prefer AT&T’s system, you might want to update to iOS 9.3 ASAP.
