I can't get a signal on my mobile phone. Can someone send me a message?

The phone can't receive the message until it receives the signal again. The specific reasons for not receiving SMS are as follows:

1. Cell phone signal is a kind of high-frequency electromagnetic wave. The sound wave is encrypted, loaded on the high-frequency electric wave generated by the cell phone's own circuit, amplified by the power amplifier, and sent to the nearest mobile base station through the antenna. The base station is connected to the switch in the computer room through wires. ? 2. The switch is connected to the nearest base station of another mobile phone through a wire. The base station sends out a signal, which is received by another mobile phone through a known channel, and the other mobile phone becomes sound waves after demodulation and decryption.

If the mobile phone has no signal, it will not receive the signal from the base station, and naturally there is no way to receive the information. So when the mobile phone can receive the signal, it will receive the signal from the base station, as well as text messages, phone calls and so on. You can receive it naturally.
