AT&T today enabled WiFi calling on the iPhone. iPhone owners who’ve updated to iOS 9 can make and receive voice calls via WiFi rather than cellular networks.
The feature is meant to help people remain connected when cellular coverage is poor. WiFi calling can be set up directly from the iPhone and requires several steps. AT&T says customers have to have a post-paid account set-up wth HD Voice in order to activate the feature. WiFi calling works automatically with the subscriber’s existing phone number. The service is free to use.
Earlier this week, the FCC granted AT&T permission to offer WiFi calling by approving a waiver concerning services for hard-of-hearing customers. Sprint and T-Mobile have offered WiFi calling for the better part of a year with no such waiver from the FCC.
AT&T chided the FCC for failing to take any sort of corrective action against them.
