I normally avoid calling an unknown +48 number back immediately, especially when there’s no voicemail explaining why they called. A quick search can sometimes provide useful context before you decide what to do. I’d try https://scannero.com/who-called-me/poland/ and enter the number to see if any information or user reports are available. If nothing useful comes up, I’d wait and see whether the caller tries again or leaves a message.
