The Imessage sent by Apple's mobile phone did not show that it had been delivered. Didn't the other party receive it?

1. Maybe the other party didn't receive the message.

2. It may be that the network delay caused the other party to receive the message, but the mobile phone did not display "Sent".

The difference between iMessage and SMS

1.iMessage is an instant messaging software launched by Apple, which can not only send short messages, but also send videos, address books, location information and photos.

2. If you turn on iMessage, by default, you will use iMessage to send messages without charge. The most obvious thing is that the message you sent is on a blue background. If one party doesn't turn on iMessage, that's the cost of normal SMS.

3. If the background of the information sent at this time is green, if the other party has opened iMessage but there is no network connection, although the information has been sent at this time, you can't receive the information you sent before the other party connects to the network. If the message sent through iMessage has a message receipt, you can know whether the current message has been sent. If you send an iMessage message to the other party, but you don't receive the message receipt, it means that the other party's mobile phone is not connected to the Internet. At this time, if you press the message for a long time, it will prompt the SMS service to send it.
