If the merchant sends a short message, you can get it.

There are two types of short messages: one is text or digital information directly sent or received by users through mobile phones or other telecommunication terminals, and the number of characters that users can receive and send short messages at a time is 160 English or digital characters or 70 Chinese characters.

One is MMS. Its biggest feature is that it supports multimedia functions and can transmit comprehensive content and information, including text, images, sounds, data and other multimedia formats.
