Vivoy55s signal is not good. What happened?

If the cell phone signal is not good, you can use the following methods to deal with it:

1. Please check whether metal protective shell, magnetic protective shell, magnetic bracket and other accessories are used. Metal and magnetic materials can easily interfere with signal reception. It is recommended that you remove the accessories for inspection.

2. If you are in a closed indoor environment (such as basement, elevator, etc.). ), the cell phone signal may be blocked, resulting in poor signal, you can go to the outdoor environment to check. If you are in a remote area and the signal may be poor, you can use the cell phone signal of the same operator network around you to determine whether it is the cause of network coverage.

3. Observe whether there is dirt or oxidation on the metal surface of SIM card, and check it after cleaning. If you use a tailored SIM card, it is recommended to replace it with a standard SIM card. Install the SIM card to other devices, or install other SIM cards to your mobile phone for comparative test to determine whether the SIM card is faulty. If it's because of the SIM card, I suggest you go to the operator's business hall to make up the card.

4. Go to Settings-System Management-Backup and Reset-Reset Network Settings-Select the corresponding SIM card-Reset Settings, and then use it to view it.

Note: Resetting the network settings will delete and disconnect the connection and pairing records of WLAN, mobile data network and Bluetooth. Before operation, it is recommended to back up data such as WiFi account number and password, and you can enter mobile cloud service-device cloud backup-backup data type-startup system data.

5. If the above methods can't be solved, please back up the mobile phone data in advance and take the mobile phone to vivo customer service center for testing. (Inquire about the address of vivo customer service center: go to official website /vivo Mall APP-My-Website or vivo official website Webpage-Sliding Bottom-Service Support-Service Website Inquiry-Select provinces and cities to inquire about the address of customer service center).

Tips: It is recommended to bring relevant purchase vouchers (such as purchase invoices/warranty cards/ID cards) before going, and call the staff of the service center in advance to ensure that the staff will go again during normal working hours, avoid running empty, and pay attention to safety on the way back and forth.
