How to open a dual card for vivo mobile phone?

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.

At present, vivo/iQOO mobile phones on sale all support dual card dual standby. Whether the model supports dual card dual standby, you can go to vivo official website-click My-online customer service, and enter "Manual" to contact online customer service for processing.

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