Baku:As travelers explore new options for mobile connectivity abroad, eSIM technology is gaining popularity for its digital convenience. This innovation allows users to activate mobile services on compatible devices without a physical SIM card. Travelers can easily manage multiple mobile plans with devices capable of storing more than one eSIM, tailoring their connectivity needs when abroad.

According to BERNAMA News Agency, while eSIMs provide significant advantages, they have also become a target for cybercriminals. Criminals exploit this digital process by posing as legitimate eSIM providers, using fake websites and QR codes to deceive users into revealing personal information or making payments.

Assoc Prof Dr. Zubaile Abdullah from the Centre for Cyber Security and Data Intelligence at Universiti Tun Hussein Onn Malaysia highlights that phone numbers, as part of digital identities, must be protected like banking passwords. He notes that although eSIM technology has standard security protocols set by the Global System for Mobile Communications, user access control weaknesses remain a concern.

Dr. Zubaile emphasizes that cybercriminals often bypass security controls of telecommunications companies to take over accounts. This can lead to unauthorized eSIM replacements, allowing criminals to transfer phone numbers to their devices. Users should be cautious of losing signal unexpectedly, as it might indicate unauthorized eSIM transfers.

Meanwhile, Dr. Mohsen Mohamad Hata from Universiti Teknologi MARA warns that eSIMs, while offering faster network switching and better durability, also come with cybersecurity challenges. These include 'eSIM swapping', phishing attacks on telecom portals, and the interception of activation QR codes.

He advises users to enhance their security by enabling app-based two-factor authentication, setting strong device PINs, and not sharing eSIM activation QR codes. These measures can help mitigate the risks associated with eSIM technology.
