1. Description
   VoLTE is a premium communication service, evolved from existing 2G and 3G voice/images. It is a next-generation voice service that offers high-quality voice calls over LTE as well as faster connection times compared to existing 3G voice services.

HD Voice offers HD (high definition) sound quality by using a high-quality audio codec capable of handling 2.2 times wider frequency bandwidth than that of 3G voice calls to make customers feel as if the person on the other end of the line is sitting right next to him/her. Moreover, the call connection time is less than 0.25 to 2.5 seconds, 2 to 20 times shorter than 3G voice calls that require an average of 5 seconds to connect a call.

In addition, it offers various value-added services including caller ID and the automatic forwarding of incoming calls, which were also provided by existing 2G and 3G voice services.
