eSIM & SIM Swap Fraud Surges: A New Threat in the Digital Banking Era

SIM swap and eSIM hijacking cases in Asia double in 2025, threatening the security of digital banking and personal identity. Biometric authentication and real-time device monitoring are now a must.


Beware of eSIM & SIM Swap Fraud — A Rising Risk in the Age of Mobile Banking.
Cases of eSIM and SIM swap fraud have doubled across Asia in the first half of 2025. This type of cyberattack allows criminals to hijack a victim’s phone number, then infiltrate their mobile banking, e-wallet, and digital accounts. Without extra layers of protection—such as biometrics, OTP with device binding, and real-time suspicious activity monitoring—users are highly vulnerable to identity theft and financial loss.

Alarming Surge in eSIM & SIM Swap Attacks Across Asia

According to a July 1, 2025, report by Reuters, cases of SIM swap and eSIM-based fraud have more than doubled across Asia compared to the same period last year. The rapid rise of mobile banking and digital wallets since the pandemic has turned phone numbers into critical identity keys.

Cybercriminals are now targeting weaknesses in SMS-based verification systems, still used by many financial institutions. Once a phone number is hijacked, attackers can intercept one-time passwords (OTPs) and security notifications, allowing them to take over bank accounts, email, and even corporate logins.

How eSIM & SIM Swap Fraud Works

These attacks usually begin with social engineering or phishing. Criminals gather a victim’s personal data from social media, leaked databases, or fake websites. They then impersonate the victim and contact a mobile carrier to request a SIM replacement—or worse, activate an eSIM on a new device.

Once the hijack is successful, the attacker gains full access to calls, SMS messages, and any OTPs sent to the number. Since many financial apps still rely on SMS verification, the consequences can be devastating.

Financial Sector and Startups at Higher Risk

Digital banks, fintech platforms, and investment apps are particularly vulnerable—especially those still relying solely on SMS OTP and basic login credentials.

Data from the Asian Financial Security Consortium (AFSC) revealed that 42% of SIM swap victims in 2025 were under age 35—those most active in using mobile-first financial services. Startups with minimal investment in cybersecurity infrastructure are also frequent targets.

The Cost: More Than Just Money

The damage from SIM swap attacks extends beyond stolen funds. Victims can lose access to essential accounts like email, cloud storage, office apps (e.g., Google Workspace, Slack), and even personal messaging platforms like WhatsApp.

According to Kaspersky Asia, the average loss per victim ranges between USD 500 to USD 10,000, depending on how many services were compromised. In some cases, recovery takes weeks, causing emotional stress and professional disruption.

Outdated Security: Why SMS OTP Is No Longer Enough

This wave of attacks shows that SMS OTP is no longer a sufficient safeguard. New security strategies are required—ones that include:

  • Biometric authentication (facial or fingerprint recognition)
  • Time-based one-time passwords (TOTP) generated by apps
  • Device binding: restricts access to registered devices only
  • Real-time login monitoring and anomaly alerts
  • Audit trails to track user access and activity logs

Security vendors now recommend layered defenses that combine behavioral analytics, encrypted identity tokens, and biometric authentication.

Government Regulations and Policy Responses

Governments across Asia are starting to respond. In Indonesia, the National Cyber and Crypto Agency (BSSN) and the Financial Services Authority (OJK) have issued updated digital security guidelines, including mandates for multi-factor authentication (MFA) in finance and e-commerce sectors.

The Personal Data Protection Law (UU PDP), which took effect in 2025, also requires digital companies to proactively protect user data—covering everything from secure data storage to preventing identity hijack via SIM swap.

In countries like Singapore and India, telcos have been mandated to implement biometric verification before approving SIM swaps or eSIM activations—adding a valuable layer of defense.

The Role of Technology Providers: Beeza’s Adaptive Security Solutions

Security technology companies such as Beeza are helping fill the gap with smart authentication solutions. Beeza provides:

  • Biometric verification for user login
  • Encrypted digital signatures

By integrating Beeza’s digital identity technology, financial institutions, startups, and digital platforms can secure user data and account integrity without sacrificing speed or user experience.

End-User Awareness Is Crucial

Users play a central role in preventing SIM swap and eSIM fraud. Best practices include:

  • Never sharing OTPs or personal data via call or message
  • Limiting the amount of personal data shared on social media
  • Enabling biometric login and MFA on all apps
  • Using password managers to secure logins
  • Enabling device notifications for unusual activity

Educating end-users is a long-term investment that pays off in both individual safety and systemic resilience.

Conclusion: Phone Numbers Are the New Digital Key — Protect Them

In a mobile-first world, your phone number is more than just a contact detail—it’s the gateway to your digital life. If criminals hijack it, they gain access to everything from your savings to your identity.

The response must be multi-faceted: improved authentication methods, smarter monitoring systems, responsible telecom policies, and user vigilance.
