Numerical value, which can be used to accurately indicate the strength of the mobile phone signal in numbers. And it allows you to switch between the grid and the value by doing the following: the lower the number, the worse the signal.

In general, between -40 and -50 is near the base station.

The signal between 50 and 60 is very good;

The signal between 60 and 70 is considered good;

Between 70 and 80, the signal is slightly weaker;

Between 80 and 90 is a weak signal;

Below 90 is the basic communication state.

100, it is recommended to sleep at night or turn on airplane mode.

Let's do it, otherwise it consumes power and radiates a lot!

Manually select the carrier.

Your iPhone will automatically connect to the appropriate network based on your card. However, the iPhone sometimes has convulsions, if you have a poor signal, you can manually select the network to try. Go to [Settings] - [Carrier] - [Turn off auto] and so on, search out the network, and then select the corresponding carrier according to your card.

For example, mine is a mobile card and chooses China Mobile.

Toggle airplane mode on and off.

Sometimes we are in a cross-base station position, and the signal diving is unstable. You can try toggling the airplane mode, first turn on the airplane mode for 5 seconds and then turn it off, and then see if your signal is full of health.

Reset the network. If you try the above two methods, the signal is still very poor, it may be a problem with your network settings, you can try to reset the network to see if the signal improves! Method: Go to [Settings] - [General] - [Restore] - [Reset Network Settings].

Flash the recovery system.

If none of the above methods can solve the signal problem, it may be a system or hardware problem. You can try to make a full backup of your phone with iTunes first, and then restore it. If it still doesn't work, you can only go to the after-sales inspection to replace the machine.

The general reasons for the sudden lack of signal on the Apple 11 are as follows:

2.Turn your phone off and restart it. Here's how:

First quickly press Volume Plus and then let go, quickly press Volume Down and then let go, and finally long press the Side button until the iPhone turns back on and the Apple logo appears.

Apple 11 network card can only go to a place with a better signal to surf the Internet, or change to a ** card of another operator, or connect to wifi to use, the network card has nothing to do with the mobile phone, only has a relationship with the signal!!
