As we changed from 2G, 3G we gave interest only on data speed, not on The quality of Calls which is the main concern of the Mobile phone and there was no major improvements on the call quality
But in recent days, we are seeing new advancement in call quality that is VoLTE
VoLTE means Voice over LTE or Voice over Long term Evolution means transmiting and recieving voice on a LTE network or 4g network
What was happening before VoLTE
For example, you were subscribed to 3G network, but when you call, the call was send by using smallest bandwidth given to you by the cellular network. due to this there was call drops was more, took more time toi connect, voice lagging and quality of voice was not good
But in VoLTE what happens is, when you call somebody, The voice goes in HD quality on LTE/4G network,means connection is ultra fast because network knows it is a VoLTE call and gives preference in the network to call, due to this delay in voice is reduced and call drops will be minimum and you will be able to listen HD quality crystal clear voice
Also, when you are using 2G or 3G when you make a call the cellular data disconnects and cellular data is resumed after the call is terminated after some time. The resume time in VoLTE is very less, say Instantaneously.
