What kind of vivo mobile phone, the signal is so poor, the network speed is so slow, it is more garb

If it brings a bad experience, please understand, it is recommended that you can try the following methods:

1. Change the network environment.

The mobile phone is in some tall buildings, basements, parking lots, etc., which will affect the signal; If you are in a closed place (e.g., an elevator) or in a remote area, it is easier to disconnect your phone from the outside world.

You can try changing places to see if there is a change in the cell phone signal.

2. Re-register the network.

You can restart your phone to let it re-register for the network.

3. Determine whether the SIM card is valid.

If the SIM card is not installed properly, or the SIM card is damaged, the signal will inevitably be affected.

You can remove the SIM card and reinstall it, or try a different SIM card.

Fourth, the operator's network problems.

If the signal of the mobile phone suddenly deteriorates during a certain period of time, it may be a problem with the operator's network.

It is recommended to compare mobile phones with the same carrier SIM card in the same environment to see if there is the same situation, and you can try it at another time period.

5. Whether to use a metal protective shell.

The metal case will have a certain impact on the phone signal.

It is recommended to remove the metal protective case, replace the factory mobile phone protective case to protect the mobile phone, and then observe and use it.
