How does vivos5 turn on volte?

VoLTE is an operator based on 4G network, which realizes the unified bearing of data services, voice calls, video calls and SMS/MMS services through IP transmission technology. Under the VoLTE network, the voice call quality is better and clearer, the call waiting time is shorter (the connection time is as short as 3 seconds), and you can surf the Internet while talking, and the data network will not be disconnected. The daily use of the VoLTE function will make the communication experience better.

At present, the system turns on the VoLTE HD calling function by default, and there is no setting option. Just contact the operator to start the VoLTE service and use it under the coverage of VoLTE network.

The contact numbers of the four major domestic operators are: 10099 (China Radio and Television), 10086 (China Mobile),10 (China Unicom) and 10000 (China Telecom), so you can call them in time.
