VoLTE stands for “Voice over Long-Term Evolution.” It is a technology standard for delivering voice communication and multimedia sessions over 4G LTE (Long-Term Evolution) networks.

LTE is a high-speed wireless communication standard used by mobile devices to access the internet and other services. Traditional voice calls on mobile networks use circuit-switched technology, while VoLTE employs packet-switched technology, which is the same technology used for transmitting data over the internet. VoLTE enables high-quality voice calls, faster call setup times, and better overall call reliability compared to traditional voice services on 2G or 3G networks.
