VoLTE stands for Voice over Long-Term Evolution, and is a technology that allows high-quality voice calls to be made over SIMBA’s 4G network. VoLTE allows for higher quality voice calls with better clarity and reduced background noise. It also allows for faster call setup times and the ability to use data services while on a call, such as browsing the internet, using a map application or tethering. Talk about a true multitasking experience!
