1, iMessage and SMS:

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

2. If iMessage is turned on, the default is to send messages with iMessage, and the traffic will not be deducted. The most obvious thing is that the message is on a blue background. If one party does not enable iMessage, it is 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, it will not be received until the other party is connected 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 don't receive a message receipt when sending an iMessage message to the other party, 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.
