identify this czech song?

i'm looking for a czech song i heard on a czech radio station when i was in northern austria, near the border, a few months, maybe even a year ago.
a woman sings it, she has a deep voice and sounds a bit angry, it's a powerful song, i'd say genre pop/rock. i didn't understand the czech lyrics but in the refrain it says "sms". i heard that song two or three times within a week so it must be qiet popular.
i hope someone knows this song

try this one, but i am really not sure, cause there is not so many times said ,,sms" ....dont u remember something more?
