Can mobile workers see the content of the short message (emergency)

I do not see any at all. Generally, moving people and high-level people can't see it!

Now it seems that there is no way. If I could see it, there wouldn't be so many spam messages now!

Didn't you get it? Selling guns and smuggling cars!

On the other hand, what can I do if I can see it? Now that there are so many mobile phones, how many waiters are there? Can you see it? Not just one or two. Will they spare so many resources?
