Why didn't I receive the text message after 1 hour?

First, strictly speaking, if the other party's phone is turned off or there is no signal, the sent SMS can only be saved for 72 hours at most, that is, 3 days. This is the case in most areas of China Mobile, some areas may be longer, but most of them are 72 hours. If the phone is turned off or there is no signal for more than 3 days, you won't receive the text message.

Second, you need to confirm whether the short message you sent at that time was sent successfully, and only those who sent it successfully can receive it. I have encountered many such situations, because the signal may be weak during transmission, or there is something wrong with the network signal, and the transmission will be delayed and unsuccessful.

Third, you need to confirm whether the other party's mobile phone is equipped with special shielding software and refuse other people's short messages.

Fourth, the model and brand of mobile phone will not affect the sending and receiving of ordinary short messages.
