VoLTE stands for Voice over LTE, and we usually call LTE 4G. So it means calling via the 4G network. Just as when you browse on a mobile device, when you call via 4G your connection is made a lot faster than via 3G or 2G. The mobile rings after barely 2.6 seconds, rather than 7 seconds. That’s an average when calling from and to VoLTE-compatible devices. In addition, you can call and browse at the same time. In the car for instance, you can call and use a GPS app simultaneously.
