A few carriers have announced plans for WiFi calling on their devices, and it looks like Verizon will follow suit. Unfortunately, the feature won't be coming to the carrier anytime soon. Verizon's Fran Shammo claims that Verizon still needs to do some of the technological legwork to make sure that WiFi calling is an acceptable experience, and since Verizon's 3G coverage is one of the best around, they haven't felt the need to urgently push WiFi calling. Still, they plan on deploying the feature at some point in the middle of 2015, which is almost a full year away.
In place of WiFi calling, Verizon has been hard at work rolling out VoLTE which offers a comparable experience to traditional 3G calling. There still aren't many phones on Verizon's network that support VoLTE or WiFi calling, so don't expect a massive change overnight, even after Verizon allows WiFi calling next year.
