How to set dual card dual standby mode for vivo mobile phone

If you mean how to set up dual card dual standby, you can refer to the following methods:

Mobile phones supporting dual cards can achieve dual-network dual standby only by inserting two SIM cards into the mobile phone, and no additional settings are required.

(Some models support the use of two telecom cards at the same time) If two telecom cards are used at the same time, the secondary card (non-data card) must be enabled with the VoLTE service and covered by the VoLTE network.

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.

Funtouch OS 9 and above, enter Settings-Mobile Network/Dual Card and Mobile Network-Mobile/Unicom/Telecom-VoLTE HD Voice Call. If this option is not available, it will be turned on by default.

Funtouch OS 9 has the following system startup methods:

Path 1: Go to Settings-More Settings-About Mobile Phone Status-SIM Card, just open "VoLTE Call";

Path 2: Enter Settings-Telephone and turn on "VoLTE Call".
