SIM SWAP: How it works and how to prevent such events if it transpires
Learn what SIM swapping is and how to protect yourself from this growing cyber threat.
In the digital era, the risk of personal data exposure on the internet looms large. As we adopt new technologies to make our lives easier, so
do criminals devise ingenious methods to exploit them. Among these methods, SIM Swapping has emerged as a significant cyber threat. In this article, we'll demystify SIM Swapping, explaining what it is, how it works, and, most importantly, how to prevent it.
What is SIM Swapping?
SIM Swapping is a form of identity theft where criminals gain control of a victim's phone number. They port the victim's number to a new SIM card, allowing them to receive calls and messages intended for the victim. This type of fraud is also known as SIM jacking or SIM splitting.
With control over your phone number, the fraudsters can bypass two-factor authentication (2FA) or one-time passwords (OTP), granting them access to sensitive accounts, personal information, or financial assets.
How Does SIM Swapping Work?
The process begins with the fraudsters gathering as much personal information about the victim as possible. This can be anything from full names, addresses, dates of birth, or even security answers, often harvested from social media or phishing attacks.
Armed with this information, the fraudsters contact the victim's telecom provider and convince the operator that they are the account's legitimate owner. They may concoct stories about lost or damaged phones needing a number transfer. Once successful, they hijack the victim's phone number and receive calls and SMS messages.
The Aftermath of SIM Swapping
The takeover of a phone number is the initial step of the fraud. Once the fraudsters gain access, they can:
- Account Takeover: Use OTPs or 2FA codes to access your banking, social media, or online store accounts.
- Identity Fraud: Utilize personal documents and information to commit identity theft.
- Phishing: Contact your friends, family, or colleagues for personal information.
- Transaction Fraud: Spend your e-wallet credits or use linked credit cards for online shopping.
- CEO Fraud: Impersonate executives to perpetrate more complex scams.
How to Prevent SIM Swapping
Protecting yourself from SIM swapping fraud requires effort from three main stakeholders: businesses, telecom operators, and individuals.
Stricter Verification from Telecom Operators
Telecom operators should enforce stringent verification procedures to prevent unauthorized SIM swaps. Some countries' regulations mandate operators to notify customers before reassigning their number to a new SIM card.

Account Verification Using Digital Footprint Analysis
Businesses can add extra layers of security by analyzing user behavior, such as IP addresses or device configuration, to detect anomalies during login.
Finally, individuals must be vigilant and educated about the risks. Be careful with sharing personal information online, and use additional verification methods such as biometric authentication or email verification whenever possible.
