Verizon has made its Advanced Calling 1.0 feature available to the Apple iPhone 6 and 6 Plus.
The free service will pass voice calls over Verizon’s LTE 4G network rather than the cellular network. It offers high-quality voice calls and video calls.
In order to enable the service, owners of the iPhone 6 and 6 Plus need to use the settings tool to allow “voice & data” over LTE directly on their phone. Once enabled, the feature will appear as active in their Verizon account online.
VoLTE calls only work between two Verizon VoLTE-enabled devices. The only other Verizon devices that support VoLTE right now are the Samsung Galaxy S5 and the LG G2.
