How to send advertising information through Apple iMessage

IMessage is an information delivery service launched by Apple. If the sender and receiver of information are both Apple devices and the iMessage function is turned on, they can send short messages to each other while networking at the same time. Because the information text consumes little traffic, it can basically be sent free of charge. It is understood that the three major operators have strict management procedures for the unified SMS sending port, and there are also certain restrictions on the amount of SMS sent.
