Dual-card dual-standby mobile phone How can the main card access the Internet and the auxiliary card not?

If you use a Huawei mobile phone, there are many scenarios where the mobile phone can't access the Internet during the call. Please confirm the specific scenario you encountered:

1. When the main card is on the phone, the main card cannot access the Internet.

The main card needs to be enabled with the VoLTE function (supported by both the mobile phone and the operator), so that "the main card can surf the Internet when it says animation". Displaying the HD icon indicates that it has been successfully opened.

2. The secondary card can't surf the Internet when the secondary cartoon is talking.

Only when the following three conditions are met can the secondary card access the Internet:

(1) Use the dialing software provided with the system.

(2) The mobile phone supports the function of surfing the Internet when talking with cartoon characters, and the control switch has been turned on. The opening method is as follows:

Gundam emui10.0&; Gundam Magic UI 3.0: settings > wireless and network > dual card management.

EMUI 10。 X & magic UI 3. x/4.0:settings >； Mobile network > SIM card management.

You can surf the internet when you start a call or intelligently select a network card or switch the network card switch during a call. (If these three switches are not available, it means that your mobile phone does not support the secondary card to surf the Internet. )

(3) The secondary card turns on the VoLTE function, and the secondary card in the status bar of the mobile phone has an HD icon.

3. The main card can't surf the Internet when the vice cartoon is talking.

Want an animation, the main card can surf the Internet, and the mobile phone needs to meet the following conditions:

(1) This two-way function needs mobile phone support. You can inquire in official website or call Huawei's customer service staff at 950800.

(2) Dual-card 4G network is normal. Turn on the VoLTE function of the secondary card, and the secondary card will display the "HD" icon in the status bar of the mobile phone. If the main card is a telecom card, turn on the VoLTE function of the main card at the same time.

If your mobile phone meets the corresponding scene conditions and still can't access the Internet during the corresponding call, please back up the data in advance (QQ and WeChat need to be backed up separately) and bring the relevant purchase voucher to the nearby Huawei customer service center for maintenance.
