Why are Apple text messages always not delivered?

The result of SMS on Apple mobile phone shows that it has not been delivered, mostly for two reasons.

The first reason is due to the network. Because the network speed is slow or the network is very stuck, it cannot be delivered in time. Another reason is that the mobile phone is in arrears and has no data, so it cannot be sent.

If the other party shuts down or is out of the service area for a long time, the information can only be stored in the center for 48 hours and then the information will become invalid. It is recommended that the user find a way to tell the other party to turn on the phone. Another possibility is that the other party's text message inbox is full and the text message cannot be reached. It is recommended that the user can tell the other party to clear the inbox.

Note:

Some simple work communications between colleagues can be conducted through text messages. However, unless the boss actively requests it or obtains his consent in advance, subordinates cannot discuss work with their superiors through text messages. .

SMS reminder: For some important appointments, you can use text messages to remind the other party tactfully, which is more polite than multiple phone calls to confirm. But it should be noted that before sending a text message, you must conduct an invitation or confirmation by phone or in person.

When forwarding text messages, you must pay special attention to the content of the text messages. Ridiculous, unhealthy, and prank text messages must be sent with caution.
