Every day, I receive two multimedia messages of inexplicable number size, only a few tens of kb, and there is no theme. What if I can only harass and intercept?

You said that your mobile phone receives two messages every day, and the size of an inexplicable number is only a few 10 KB. No theme MMS, only harassment interception. What should I do? I think we can intercept these inexplicable short messages directly, because one of these short messages is not about tearing up the special code, but asking you to do some online gambling and other sales promotion. Leave it alone and pretend it doesn't exist, or use interception software. Just clean up these messages and intercept them.
