AT&T Hopes to Launch WiFi Calling On iPhone Soon
Sep 17, 2015, 10:21 AM by Eric M. Zeman
The iOS 9 update, made available by Apple this week, added a WiFi Calling option to AT&T's version of the Apple iPhone. Despite the feature's appearance on the handset, the service isn't quite ready. AT&T is waiting for the FCC to grant a waiver with respect to real-time text (RTT) as an alternative for the out-going TTY technology used by the hard-of-hearing. AT&T requested the waiver earlier this year. The company wants to use WiFi to supplement its cellular network in some areas, but TTY is unreliable when used over WiFi. The RTT technology to replace it is nearly ready, but requires a rule change from the FCC before AT&T can move forward. "AT&T tested WiFi Calling through the iOS 9 beta and we are prepared to support commercial launch of the service once approved by the FCC," said AT&T in an email to Phone Scoop. AT&T customers who signed up for WiFi Calling through the iOS 9 beta are still able to use it, even though the service isn't officially available. Such beta testers will be notified when the service goes live for everyone. The FCC hasn't said if or when it may approve AT&T's request. WiFi Calling has been available to Sprint and T-Mobile iPhones for some time.
