How to judge that the other party's mobile phone has a signal?

In daily life, we often encounter the situation that the other party's mobile phone can't be connected. At this time, it is necessary to judge whether the other party's mobile phone has a signal. Here are some ways to judge whether the other party's mobile phone has a signal.

Method 1: Observe the icon of cell phone signal strength.

Most mobile phones have signal strength icons, usually several vertical bars. If there is a signal, the vertical bar will be displayed, otherwise the vertical bar will not be displayed. If the signal strength icon of the other party's mobile phone is not displayed, it means that the other party's mobile phone has no signal.

Method 2: Call the other party's mobile phone.

If the other party's mobile phone has no signal, then you can't reach the other party's mobile phone. If you hear a busy tone or a busy tone when dialing the other party's mobile phone, it means that the other party's mobile phone has no signal.

Method 3: Send short messages to the other party's mobile phone.

If the other party's mobile phone has no signal, you can't send text messages to the other party's mobile phone. If you receive a message of sending failure when sending a text message, it means that the other party's mobile phone has no signal.

The above is the way to judge whether the other party's mobile phone has a signal. If you find that the other party's mobile phone has no signal, you need to wait for the other party's mobile phone to recover the signal. At the same time, if your mobile phone often has no signal, then you need to check whether your mobile phone is a hardware failure or a network problem.
