How to send bulk SMS

[David.SM]

Hello everybody.
I use MIUI 13 on Redmi 9.
I want to send SMS to my friends group.




I created group in Google Contacts and selected option to send SMS to all of them.
When I created converation I saw that MMS was created.

Spoiler: Please view screenshots

I don't want MMS. I want SMS. What should I do to send SMS instead of MMS?
