One will appear on your cell phone or phone screen unknown number? Sometimes this can mean that the call is spam. If you are literally bombarded by them, you can report them to platforms such as Clever Dialer or tellows. Each month, both websites compile the spam numbers users have complained about most often. You shouldn’t call back on any of the following. If you receive a call, you can safely hang up or not answer at all.

Keep this in mind when calling
– Healthy distrust is important and not rude
– Never reveal passwords or account details
– Never share your electricity meter reading
– Courts, banks and authorities will never ask you to pay over the phone
– Never allow remote access to your PC

Beware of these 19 unknown numbers

Not only is it very annoying to be called regularly from unknown numbers, but it can also be dangerous if you fall for fraudsters on the phone.

Often there are spam callers on the other side of the line: inside who answer very authentically with name and company, but want to sell you a new contract or competition in which you lose something rather than win. Above all, you should make sure that you don’t say “yes” on the phone.

As in the previous months, Clever Dialer detected ten phone spam numbers for the period November 2021. You should be careful of these unknown numbers. You can safely ignore them:
