At the same time, it has an ultra-low dial-up waiting time, only about 2 seconds, compared with the previous dial-up. Wait at least 6-7 seconds, and the drop rate of VoLTE is almost zero. In other words, VoLTE is a more advanced communication technology than the previous generation. It is completely based on 4G network and has the characteristics of fast speed, good communication quality and low dropout rate.

It is built on the operator's network, which means that operators can provide a higher level of control and management for VoLTE. WeChat Phonebook and FaceTime are OTT VoIP services that rely on the network to exchange data packets. Once they rely on the network, their stability becomes erratic.
