Today Verizon has turned on VoLTE (Voice over LTE) functionality across its network in the United States. This means you’ll be able to make voice calls over Big Red’s 4G network too, as up until now you would have been bumped onto its 3G network for this purpose (LTE was data-only).
This move will enable crystal clear HD quality voice calls, six-way conference calls, and even support for native video calling. This works without using an app – like 3G native video calls, if anyone remembers those. You can switch from a video call to an HD voice call and back with one tap.
There are some caveats for all this, as you might expect. The VoLTE functionality is currently only available to you if you have a supported device. The list of those is pretty small right now, including only the LG G2 and Samsung Galaxy S5. That said, software updates enabling VoLTE will probably be issued for other smartphones soon.
