How do I find out who called me?

I always have calls ** or ** on my cell phone, when I call back it hangs up. Are these advertising calls?

Thank you very much for the information.

Kind regards…Marcel

You can enter the number at https://www.search.ch/ and with a bit of luck the owner will be displayed.

Also note the following knowledge post for such calls: [Spoofing: Be skeptical about unexpected calls](https://community.swisscom.ch/t5/telefonie-Wissensbox/Spoofing-Sei-skeptic-bei-unerwarteten-Anrufen/m-p/567799# U567799)

In general, you should not return calls from unknown senders as this can lead to you being bothered even more by such unknown calls.

Have you already activated the blocking against such calls in Kundencenter mySwisscom?
