Can Shaoguan Unicom card apply for HD calling function?

Unicom has recently upgraded the latest VoLTE function. You only need to upgrade the mobile phone software system to the latest version, and turn on the VoLTE switch in the mobile phone setting interface, so you can enjoy the convenience of receiving calls and high-definition voice and video calls on the Internet brought by VoLTE. The connection is faster and the sound quality is better. The tariff standard is the same as the current package voice and video phone. If you set up call forwarding, you may need to reset the call forwarding number. If you still need to use the ringtone function, you can send KTYP to 10655 158, and it will be opened for free within 24 hours. To turn off the VoLTE function, you can edit the short message TDVOLTE and send it to 100 10.
