What should I do if the mobile phone network is poor?

Poor network quality, traffic speed limit, wrong use of protective shell and wrong setting may all lead to slow internet access. If you use a vivo phone, you can refer to the following methods for troubleshooting:

1, the reason of poor network quality

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

2, check the phone settings

Please open the shortcut bar of your mobile phone (slide the top down or the bottom up) 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 is also displayed in other mobile phones, it may be the slow network caused by the SIM card itself. Please contact the operator for feedback.

Step 4 check the cell phone signal

If the mobile phone uses a metal or magnetic protective case or bracket, such a protective case and bracket will affect the signal of the mobile phone. It is recommended to take it off and try it.

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 has been used, please close it and try again.

6. Check the network settings

Please go to 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 phone.

7. Reset network settings

Resetting network settings will delete the connection records of WLAN, mobile data network, Bluetooth and other networks. You can enter Settings-System Management-Backup and Reset-Reset Network Settings-Reset Settings-Follow the prompts (you need to select the corresponding SIM card for dual cards). note:

1, enter the cloud service-data synchronization-turn on WLAN, Bluetooth, etc. Synchronize data to the cloud service.

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 method, WiFi, default opening program, etc. note:

Enter cloud service-device cloud backup-backup data type-system data-return-immediately back up some backup system settings and desktop layout;

Cloud service-data synchronization-turn on WLAN and Bluetooth to synchronize data to cloud service.

9, service center testing

If the above methods fail to solve the problem, please back up the mobile phone data in advance and take the mobile phone and purchase certificate to vivo customer service center for testing. Go to official website /vivo Mall APP-My-outlet to inquire or click the webpage link, and select the current city to get the address and contact information of the service center. It is recommended to call in advance before going to avoid empty running, plan your trip reasonably and travel safely.
