Spam SMS containing random symbols [very strange]

[dubbajohnny]

About four-five days ago I've began receiving text messages from the number "9999999999".(I'm aware it's not a real number) The texts always contain random symbols, no actual words. It's not a foreign language, it's honestly pure symbols. They had hit the 100mark as of yesterday. 100 text messages received from this nut. I receive them at all times of the day and my number is on the do not call list. (not sure if that applies to texting, but yeah..)

I did not reply to them until yesterday where I sent stop, end, #, etc in attempt to end the madness. I've also blocked the number "9999999999" using my phone providers websites.
All my attempts to prevent the texts have failed. I still get them from the same 999 number.

Example of such text is "� `P ?� €\ 13 ƒƒcK ?K{q{?s!s? skk™kk+›› ;( |$o??$d ? +?r33q??3;R?
)ƒ? lŒH? Y‰? ?ɡ?‘ ? z??‚)?‚bjp 4T p
?l@, DŽ C?? ?y{kk›"
While doing a google search that contained a small portion of a text I've received, THESE are the result. Broken webpages with the same symbols I receive just in a different order.

I want two things to be honest... A method to stopping this and to know what the text is written in so maybe I could decode it and find out what each text says. I want them both equally the same.(damn my curiosity.)​

All replies are welcome and would be greatly appreciated. Thanks for your time.

I would call your carrier and have them block them at the SMS Gateway.

I get them after a scam IRS call on my phone. Connection? Ya think!. I want to block and Verizon says it's not a real phone number so can't.
