How to activate China Unicom volte

1. China Unicom’s VoLTE service can be activated through SMS, and there is no need to go to the business hall. Edit the text message "DGVOLTE" and send it to 10010. After receiving the confirmation text message, reply "Y" to activate it.

2. The most direct experience that VoLTE technology brings to 4G users is shorter waiting time for connection, and higher quality and more natural voice and video call effects. VoLTE is fundamentally different from 2G and 3G voice calls. VoLTE is an end-to-end voice solution based on all-IP conditions on the 4G network.

Compared with 2G and 3G voice calls, the voice quality of VoLTE can be improved by about 40% because it uses high-resolution codec technology. VoLTE brings users lower access latency (waiting time after dialing), 50% lower than 3G, about 2 seconds, while it was 6-7 seconds in the 2G era. In addition, under 2G and 3G, call drops occur from time to time, but the call drop rate of VoLTE is close to zero.
