I just received a short message from 100 1700. I seem to need to download something. Who knows where this message is? Is it necessary to open it?

MMS must be connected to WAP network, that is, the network where you usually surf the Internet with your mobile phone. After connecting to the network, spend a little traffic and click download to know what a short message is. Generally, such short messages are advertisements, activities and the like.

The expiration time generally refers to the time when this short message is stored on the server. 1October 24th 10: 06 When the storage time expires, even if you click Download, it is gone, and the message is brushed off by the server.
