What should I do if I am harassed by short messages from anonymous websites every day? Is there any way to block it?

Complaining to mobile can sometimes be solved! But you can't block it all!

Because there are too many such complaints, it is impossible to block every individual customer!

But if it becomes large-scale, Mobile will take action to block this number!

Personal best way is to change the number!

Going to the regular business hall, the number bought by the roadside will have such a problem!
