O2 scam calls – How to get rid of scam calls


Be aware of those numbers?

Telephone scams and dubious calls are and will remain an issue that will not lose its relevance anytime soon. Quite the contrary. Every day, individuals continue to be confronted with the fraudulent stories of unscrupulous scammers. 

The reasons given for the calls cover a wide range: from the delivery of shocking news to the announcement of an alleged profit. Often it is not easy to see through the scam, let alone keep track of it. For this reason, tellows has made it a business to always inform and warn you about the latest unwanted, dubious phone numbers.

Attention! Be skeptical with these callers

The listed call numbers were searched for particular frequency by tellows users in June 2022 and accordingly often rated negatively. The comments show that the scammers have a very strong Indian accent and are claiming to be working for O2 company. Be careful, official numbers are often targeted by scammers who manipulate phone numbers via spoofing, and their main goal, in this case, according to the comments is always to either get your personal data or your money directly with the “excuse” of the need to renovate the contract. What is particularly striking about June’s unwanted numbers is that virtually all of them started their activity of contacting people this month, for this reason, it is important to stay informed about the latest dubious numbers.

Leider ist der Eintrag nur auf Amerikanisches Englisch verfügbar.

We’ve all seen spam and fraud in our everyday life. Luckily, it is often easy to see through them before it is too late. But especially on the phone, it can be tricky to distinguish a genuine call from a scam call. On we receive reports about scam callers everyday. The users may ask themselves, why is the person calling me? The caller already knows my name and address, so it has to be trustworthy, right? – No way! We tell you what common frauds look like and how you can protect yourself from them.

Scamwatch published the top 10 scam methods of 2021. Phishing is the most reported scam showing how dangerous this scam has become and that exercising precaution with sharing data is the number one priority.

Common Types of Scams

Scammers like to tell stories and make you believe that the call is urgent by putting pressure on you. For example there is a time senstitive event with only limited offers left or your safety is at risk when you don’t allow access to your computer or pay a debt immediately. Sometimes they pretend to be from well-known company or your insurance. Maybe you also receive a text message or a silent call where you have no chance to even answer the phone. These are just some tricks Australian scammers use to make you call back and share sensitive data.

It’s very concerning to see these scams evolving and becoming more sophisticated to steal even more money from unsuspecting people. – ACCC Deputy Chair Delia Rickard

(English) How has the Covid pandemic affected telephone spam worldwide?


Leider ist der Eintrag nur auf Amerikanisches Englisch verfügbar.

We have been living with the restrictions that the Covid19 virus brings with it for six months. The time cuts are different in many countries and regions. The economy around the world is severely affected by the effects and regulations of the government. But how has calling behavior changed during the pandemic?

Fewer calls in lockdown

Almost every company needs the telephone in everyday life, regardless of whether it is for daily customer support, consultation or appointment arrangements, or sales and acquisition. Due to the restrictions in daily work and the increase in home office activities, the number of calls has changed in many places. Many companies have not only moved their work home, but have been forced to severely restrict business lines.

This is reflected in calling behavior, which has changed significantly during the pandemic and especially during the strict lockdown. External telephony was greatly reduced, not only because other companies were less accessible and technically poorly equipped at home, the economic situation also meant that appointments, support or expenses through sales and collaborations were not made or were limited until further notice. This also applies to call centers and companies that use phone calls for undesirable purposes such as telephone spam, advertising or even fraud.

tellows shows the history of caller activity in different countries

Even on tellows we experienced fewer reported calls and fewer numbers were searched, which is noticeable in the low number of calls made in general.

In the following diagram, we show you the caller behavior over time in the UK and France.

(English) The 7 biggest myths about telephone scam and Co.


Leider ist der Eintrag nur auf Amerikanisches Englisch verfügbar.

Dear tellows-fellows,

Superficial knowledge can be dangerous, we all know that. In terms of telephone advertising and fraud, it can cost you a lot of money and nerves! Therefore, today we present you the most common myths regarding telephone advertising, telephone fraud and possible manipulations on tellows and clearify them.

money transfer

1. Telephone scam only affects older people

As soon as one hears of telephone scam, one has more in mind the 93-year-old Mary-Ann, who was tricked by fraudsters, than the 26-year-old computer science student Stella. The fact is: Fraudsters often try to scam older target groups since they tend to be less careful and easier to be fooled. They are not always informed about the latest phone scam tricks, so a call from an alleged family member or the bank employee can turn into a costly trap.

However, this does not mean that everyone else can think themselves safe. Since there are many types of fraud, the victims differ. There are even tricks that mainly lead to success for the fraudsters among younger people. Such an example would be the Microsoft support scam, which targets access to sensitive data from their victims on the phone. According to Microsoft, this stitch is particularly successful in the age group of 18 to 34 years.

2. As long as I don’t give out any data about myself, I can’t lose any money

Unfortunately, this is also a misconception. It is true that you should never reveal your data on the phone, but there are other ways to get your money. Ping calls pose a great risk here. In this case, the fraudsters ring only a few seconds to provoke a recall. If this is done, a high fee will be charged, as the numbers are often foreign and you will be drawn into a waiting loop that can cost you a lot of money per minute.
