Apple 6 sends text messages to each other. How do I know if the other party has received the text message?

As long as the message panel shows that the message has been sent, the other party will receive it when it is turned on again.

You can set the IPhone SMS reading receipt.

The specific setting steps are as follows:

Go to Desktop Settings;

Go to Information under Settings;

Just turn the Send Read Receipt switch on or off as needed.

Between Apple devices (including ipad, provided the id is registered), if the network is open, Imessage can be used. You can send a short message to the other party for free. Do you have a reminder to send it or not? Does the other party read the short message?

If there is no wifi or cellular mobile data between Apple devices, it can only be sent in the form of SMS, charging the SMS function fee, and it will show whether it is sent to.

Between Apple and other mobile phones, it is the same as the second point. The sending status is displayed in the lower right corner of the message.
