What does a silent call from 04 2190 4411 mean?
A silent call from 04 2190 4411 (0421904411) means the caller intentionally does not speak when you answer.

Silent calls are sometimes used as a first contact before more aggressive follow-up attempts.
Should I call back 0421904411?
No, you should not call back 0421904411.
