While user vigilance remains essential, technical solutions also play a key role in improving data security.
Yettel is enhancing the protection of customer accounts while simultaneously making login processes more convenient. As part of this effort, affected customers are asked to provide any missing details and update their information. Keeping email addresses and phone numbers up to date ensures reliable communication, while modern two-factor authentication helps detect and prevent potential fraud attempts. The long-term goal aim of Yettel’s campaign is to maintain a secure login environment while encouraging customers to use the company’s official mobile app as their primary point of contact. This approach further strengthens the protection of subscription-related data and account management.
Customers who update their data by 25 April 2026 can continue to enjoy seamless access to their Yettel account using their email address. After this deadline, customers who have not completed the update will only be able to log in via SMS code, with limited functionality. However, they will still have the option to create a new account, effectively replacing the missed data update.
With fraudulent phishing attempts – often impersonating large companies and requesting personal data – becoming increasingly widespread, public trust in such communications has understandably declined. Although the campaign has been progressing as expected, the experience of one prize winner demonstrates the unintended consequences of heightened caution: despite legitimate notifications, the customer declined their valuable iPhone 17 prize, assuming it was not genuine.
What information does Yettel request from customers during the data update, and how is it collected?
To ensure the security of customer accounts, Yettel contacts affected customers via email, with additional notifications available through the official app and on the Yettel account login page. Data updates are carried out exclusively through secure, verified channels, including the Digital Authentication Platform (DAP), video chat, or SMS confirmation initiated by the customer. If a message – even one appearing to come from an operator – requests personal data in an unusual or unverified way, it should be treated as a scam.
The data update process takes only a few minutes. Among participating customers, Yettel selects a winner every Thursday. Each winner receives a one-year Prime Extra subscription free of charge, along with either an Apple iPhone 17 or a Samsung Galaxy S25 5G. The promotion is fully legitimate. Winners are officially notified by the operator via both email and phone – even if, as this case shows, some may initially find it hard to believe.
With the data update program, Yettel aims to deliver a simple account login experience, a high level of data protection, and predictable, fast digital customer service. For more information about the data update, visit: https://www.yettel.hu/fiok-frissites
