Yettel employee may have been mistaken for a phisher during anti-phishing campaign

In addition to the vigilance of internet users, there is also a technical solution to increase data security

Yettel is enhancing the security level of customer accounts, and at the same time, it wants to make it more convenient for subscribers to log in to their own user accounts, which is why its customers are affected by the missing data asks to provide and update data. The updated email address and phone number ensure that customers are actually reachable, and the modern, two-factor authentication process filters out potential abuse attempts. The goal of Yettel’s current data update campaign is to ensure that, in addition to a login system that provides an appropriate level of security, the company’s customers use the company’s official mobile application as the primary point of contact in the long term. This can increase the security of subscription-related data and administration.

Anyone who completes the data update by April 25, 2026, can continue to use their Yettel account conveniently with their own email address. After the deadline, if the data update is not completed, login will only be possible with an SMS code, and only limited functions will be available with this method. At the same time, it is also possible to create a new account to make up for the missed data update.

Since phishing attempts requesting data in the name of large companies, which are actually fraudulent, have recently become widespread, people’s trust in such requests has rightly wavered. Although the data update campaign, which has been running for weeks, is progressing at the right pace, one of the winners probably did not believe that he had really won and refused his valuable iPhone 17 winning device when notified.

What data and how does Yettel request from its customers during the data update?

 To increase the security of customer accounts, Yettel contacts its affected customers by email, and a notification about this can be found in the official application and the Yettel account login page. The company requests and records data for data updates exclusively via DÁP, video chat or SMS confirmation initiated by the customer. If an email that appears to be a service provider request requests data in a different way on behalf of Yettel, it is a scam.

The real data update process takes a few minutes, and among those who update their account that week, Yettel will draw a winner every Thursday: in addition to 1 year of free Prime Extra subscription, the lucky winner can win an Apple iPhone 17 or Samsung Galaxy S25 5G. The game is real, the service provider will officially notify the winners by email and phone – even if sometimes the winners themselves do not believe it at first.

With the data update program, Yettel aims to provide customers with a simple account login process, a high level of data protection, and predictable and fast digital administration.
