There are two versions of vivo mobile phone, namely mobile full netcom and full netcom. The specific model can be viewed in Mobile Phone Settings-More Settings-About Mobile Phone (version information). The differences between the two versions will be introduced in detail below.

Quan netcom edition

The full netcom version supports mobile, Unicom and telecom SIM cards, and can switch data networks freely, making card 1 or card 2 an Internet card, but it does not support using two telecom cards at the same time.

Mobile full netcom edition

The mobile full netcom version also supports the SIM cards of the three major operators. When using mobile cards and non-mobile cards, the mobile card will automatically lock into the network card and cannot be replaced. If you use two mobile cards or two non-mobile cards, you can manually switch data networks in the settings.

It is not supported to use two telecom cards at the same time.

Neither version supports the simultaneous use of two telecom cards.
