What is VoLTE or Voice over LTE? Reliance Jio use VoLTE for voice calls.

VoLTE is an acronym for Voice over LTE, which is based on the IP Multimedia Subsystem (IMS) network, with specific profiles for control and media planes of voice service on LTE defined by GSMA in PRD IR.92.[1] This approach results in the voice service (control and media planes) being delivered as data flows within the LTE data bearer. This means that there is no dependency on (or ultimately, requirement for) the legacy circuit-switched voice network to be maintained. VoLTE has up to three times more voice and data capacity than 3G UMTS and up to six times more than 2G GSM. Furthermore, it frees up bandwidth because VoLTE�s packets headers are smaller than those of unoptimized VoIP/LTE.

Reliance Jio uses three different network bands to provide the 4G service in India.

Band 5 (850 MHz)
Band 3 (1800 MHz)
Band 40 (2300MHz)
