Because of the signal problem, the mobile phone did not receive the text message at that time, and it will not be recycled in the future.

Even if there is no signal at that time, it will be received, because when the sent SMS does not enter the mobile phone, it can be stored for three days, and then it can be received when the signal is good. You can receive it no matter how far away. I tried to send a message to the Netherlands at home, and the other party could receive the message! If you say you didn't receive the SMS, you should first check whether your SMS capacity is full. If it is full, even if a text message enters your mobile phone, you may not find it.
