VoLTE stands for Voice over Long-Term Evolution or Voice over LTE. It is a digital packet technology that uses 4G LTE networks to route voice traffic and transmit data. VoLTE is how our phones and carriers transmit our voices during a call, and it allows us to place a phone call over our LTE connection instead of the older 3G or 2G networks. It provides higher quality calls, better service, and the ability to use voice and data simultaneously. VoLTE can help improve call quality, and it allows us to use more bandwidth to make phone calls with higher-quality audio traveling both ways. The benefits of VoLTE include fast call set-up, high voice quality, reduced background noise, and the ability to use data for games, browsing, or scrolling while talking on the phone at the same time. To use VoLTE, we need an LTE/4G-compatible phone, and our operator and subscription (including SIM card) must support VoLTE for the device model were using. We also need to make sure that VoLTE is activated in our devices settings.
