The mobile phone can't get in, can the other party receive the text message?

Maybe his cell phone doesn't receive well, and the relationship between the cell phone and the base station is two-way. If you want to talk, you must make sure that both signals can reach each other. Generally speaking, the signal of the base station is strong and it is normal for the mobile phone to receive it, but it does not mean that the signal of the mobile phone can be received by the base station.

This will cause the short message to be received and the phone to be disconnected.
