Dangerous Phone Numbers: Block Spam Calls Now

More on the subject of digital

In June, German consumers are once again targeted by spam calls.As the current evaluation of “Clever Dialer” shows, there is obviously a single call center based in hamburg behind more than half of the reported cases – disguised by a variety of different telephone numbers.

Under the guise of alleged competitions, the callers try to deceive their victims with subscription traps and the query of personal data. After a record high of spam calls had already been reported in May, 1.2 percent more had been registered in June.

Persistent spam calls from Hamburg, Düsseldorf or the Netherlands

The accumulation of calls with Hamburg landline area code was particularly striking: Among other things, the numbers 040 855983155 and 040 855983156 caused numerous complaints. “Although the numbers have been blocked,the nuisance continues because the caller changed the final number three times within three weeks.The caller is fitting anything of the end of the competition,” reports a person concerned.

Numbers from Düsseldorf (area code 0211) and one from the Netherlands (country recognition +31) also appear in the top 10 list of the most common spam numbers.the Dutch number +31 6 26295287 was often reported not only because of its persistence, but also due to presumably fraudulent intentions.

The most common spam numbers in June

In its current evaluation,the “Clever Dialer” app shows,which serves for call recognition and spam defense,which spam numbers were reported particularly frequently in June:

In the comments of the evaluation, those affected report dubious methods: for example, threatening due to alleged payment arrears or assuming an active gambling subscription that you have to cancel.

A particularly perfidious example: a woman whose husband already wanted to extend a gambling subscription described that despite her clear reference to the death, it was called after a short break.

So you can protect yourself

As a rule, the spam numbers do not remain long, the operators change again and again.You can also report a harassing call to the Federal Network Agency. This can switch off phone numbers and impose fines against operators.

You can also block phone numbers on your own smartphone or landline phone. As “TechBook” reports, phone numbers can be blocked by routers from Netgear, D-Link, Fritzboxes from AVM and others in the menu under the “Telephone” or “Fixed network” tab.

Proposal of the consumer advice center: End the noticeable conversations prematurely

If you have received such a spam call, it is indeed best not to get involved in an unwanted conversation at all, recommend the rhineland-Palatinate Consumer Center. The shooter in front of the contracts, but also to be called again and again in the future. “Ending conspicuous conversations early on: this is not rude, but our good right,” recommend consumer protection.

it is indeed meaningful not to provide unknown people on the phone about personal data and accounts.In addition, you shouldn’t say “yes” on the phone if possible. “We know reports that in extreme cases the phone call was cut together in such a way that the ‘yes’ was said at the right place to conclude a contract. there has never been a conclusion of the contract,” report consumer protection officers. If something like this happens, you can contact the consumer center and the Federal Network Agency. (SBI/Ali)
