Can I send short messages to expired mobile phones?

This depends on the specific time of arrears:

1, start to owe money, and move the call stop function first, so you can't make a phone call. You can click here to listen to and receive short messages.

2. After a week of arrears, stop answering the phone and only receive short messages.

3. One month's arrears, work stoppage, and no SMS.

4, arrears for 3 months, cancellation number. Cannot be used.

The regulations of the above places may be different, so it is suggested to call 10086 for manual consultation first.

Extended data

Mobile phone signal is a kind of high-frequency electromagnetic wave, which is encrypted, loaded on the high-frequency electric wave generated by the mobile 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.

Then the switch is connected to the nearest base station of another mobile phone through a wire, and the base station sends out a signal, which is received by another mobile phone through a 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.
