Poor network quality, traffic speed limit, wrong use of protective case, and wrong settings may all lead to slow Internet access. If using vivo mobile phone data network to access the Internet is slow, please judge the problem according to the following steps and methods:

1, reasons for poor network quality

Compared with mobile phones using the same carrier card around, if the same phenomenon appears, it may be caused by poor network quality in the current location.

2, check the phone settings

Please open the mobile phone shortcut bar (slide down at the top or slide up at the bottom) to restart the data network switch.

3. Confirm the status of the mobile phone card

Compare the SIM card with other mobile phones. If the SIM card also behaves in other mobile phones, it may be the slow network caused by the SIM card itself. Please contact the operator for feedback.

4. Check the cell phone signal

If the mobile phone uses a metal, magnetic protective case or bracket, such protective cases and brackets have an impact on the signal of the mobile phone, so it is recommended to take them off and try.

5. Check VPN (Virtual Private Network)

Please go to Settings-Other Networks and Connections --VPN to check and confirm whether VPN is used. If it is used, please close it and try again.

6. Check the network settings

Please go to mobile phone settings-mobile network (SIM card information and settings-corresponding SIM card)-access point (APN) or settings-mobile network/dual card and mobile network-access point (APN), and click "Reset to default settings" to restart the mobile phone.

7. Reset the network settings

You can enter Settings-System Management-Backup and Reset-Reset Network Settings-Reset Settings-and follow the prompts (you need to select the corresponding SIM card for dual cards). Note:

2. Enter "Cloud Service"-Device Cloud Backup-Backup Data Type-Open "System Data"-Return to the previous page-Back up immediately, and back up some system setting data.

8. Restore all settings

You can enter Settings-System Management/More Settings-Backup and Reset/Restore Factory Settings-Restore All Settings-Restore, Restore Settings Options. This operation will not delete files or software, but will cancel the password and restore all settings, including the set wallpaper, unlocking style, WiFi, default opening program, etc. Note:

9. If it is not improved, it is recommended to take the mobile phone to vivo customer service center for testing and processing.

It is suggested to call in advance before going to avoid empty running, plan the trip reasonably and travel safely.
