Why hasn't the text message reached Apple's mobile phone?

Apple's SMS results show that it was not delivered, mostly for two reasons. The first reason is because of the network, because the card with slow or very fast network speed cannot be delivered in time. Another reason is that the mobile phone is in arrears, and there is no traffic, so it cannot be sent.

If the other party is turned off or out of service for a long time, the information can only be stored in the center for 48 hours, and the information is invalid. Users are advised to find a way to inform the other party to open it. Another possibility is that the message inbox of the other party is full and the message cannot arrive. It is suggested that users can notify each other to clean up their inboxes.

Precautions:

Some simple work communication between colleagues can be carried out by SMS, but subordinates can't talk to their superiors by SMS unless their superiors ask for it or get their consent in advance. ?

SMS Reminder: For some important appointments, it is more polite to gently remind each other by SMS than to confirm by phone many times. However, it should be noted that you must invite or confirm by phone or in person before sending SMS.

When forwarding short messages, we must pay special attention to the content of short messages, and send absurd, unhealthy and mischievous short messages carefully.
