Strange SMS allegedly from Beeline

I hasten to share the text of the SMS, which woke up my tired body on Sunday afternoon.

Actually SMS was already four. The first two:

“Take a free. MMS settings. Password 1234. Free. inf. 06059 "
')
“Take a free. GPRS-WAP settings. Password 1234. Free. inf. 06059 "

After that came two messages asking for a PIN. I enter 1234 and read the text with a description of the standard settings of Beeline.

Phone sender: +79037430090 (it is clear that you can write anything here).

What is it? Another divorce? If not, why then the password? I did not request any information.
