The Indian Cybercrime Coordination Centre (I4C), a wing of the Ministry of Home Affairs, issued a strong warning to mobile users about the rapid increase in eSIM fraud in India. eSIM technology is rapidly growing in recent years. From premium smartphones to everyday devices, mobile users are shifting to embedded SIMs (eSIMs) due to their convenience, in which no physical card is required, instant activation, and easy switching between networks are done.
However, this convenience has new vulnerabilities as well. The Fraudsters are taking advantage of eSIM technology to hijack mobile numbers, intercept OTPs, and steal money from unsuspecting victims.
This blog explains the rising eSIM scam in India, why it is dangerous, real-world examples, and most importantly how you can protect yourself with the right eSIM safety tips and cyber fraud awareness practices.
How the eSIM Scam Works
The eSIM scam in India starts with social engineering. The fraudsters pose themselves as telecom operators and send fake messages, emails, or calls claiming that your SIM card needs to be upgraded or converted into an eSIM. These communications include links or instructions that look official but following them leads to getting in a trap.
Once you click the link or share your critical information, the fraudster initiates an unauthorized eSIM activation. The original physical SIM card gets deactivated, and the number is silently transferred to a device which is controlled by the criminal. From that moment, the fraudster has overall control over your calls, SMS and most importantly the OTP fraud in banking.
This way of hijacking the mobile number bypasses the traditional safeguards and allows attackers to reset passwords, authorize fund transfers, and lock victims out of their accounts.
Why the eSIM Scam is Dangerous
Unlike many other scams that require much effort, SIM swap fraud and eSIM hijacking takes just few minutes. Victims often realize the fraud only when they suddenly lose network connectivity or when the fraudsters have already made the transactions.
The telecom eSIM security loopholes make this scam particularly effective:
