The Rise of SIM Farms and Digital Identity Abuse in India: Understanding the Growing Threat of SIM Muling
Introduction
In today's interconnected world, a mobile phone number is an inseparable element of digital identity. By this number, digital identity is connected to the user's bank and social media accounts among other digital services. Unfortunately, this dependence has created a possibility for criminal use of the mobile connection and conducting digital frauds.
One of such new threats is SIM muling, when SIM cards are acquired and used in someone else's name. By using it, SIM cards can be used as SIM farms and used for committing scams and other digital frauds such as phishing, impersonation, or OTP fraud. Another concern of SIM muling is the registered SIM owner is not always the user of the SIM.
Understanding SIM Muling and the Rise of SIM Farms
SIM muling refers to the disjunction between the registered user and the SIM subscription. Criminals pay a fee to individuals to get a SIM or rent an existing SIM. Alternatively, they buy several SIM cards using fabricated identification documents. In contrast, SIM farms are a coordinated structure of many SIMs that use devices to send messages, make voice calls, and communicate via data.
Sometimes the two are interdependent: SIM farms can include SIM cards procured using SIM muling. With SIM farms, the problem that fraudsters create for users is creation of several phone numbers so that people do not try to identify the fraud
How SIM Farms are Enabling Cybercrime
One problem mobile connections at a larger scale provides to cybercriminals is the scale at which Phishing/impersonation can take place.
- Fraudsters can create several different fraudulent accounts using many mobile connections to create fraudulent messages to bank customers, government officials, or others.
- Multiple mobile connections provide more opportunities for OTP fraud and other crimes to be conducted with fraudulent mobile accounts. Some of the OTP fraud mechanisms require users to gain control over a fraudulent SIM to be able to capture and/or verify an OTP message, or to gain access to an account or other information.
- Several fake accounts and scams can be created by registering a number of fake mobile accounts. The account and scams can also be verified and cross-verified through multiple mobile accounts.
- When fraudsters use a number to register mobile connections to conduct fraudulent calls, it creates difficulties for authorities when trying to verify the identity of the person who committed the fraudulent communication.
This use of SIM cards by cybercriminals helps to facilitate multiple types of cybercrimes and scams, so telecom abuses at a smaller scale may be a symptom of a larger, more coordinated effort.
Digital Identity Abuse
The fact that people's identities are misused is the most problematic part of SIM muling. A person can think that they are helping others and making some quick cash. Once they open these connections for other people, they lose the ability to manage them. Fraudulent PoS agents can open a connection in a person’s name without their knowledge, by using their ID documents.
For example, in 2026, the Chhattisgarh Department of Telecommunications discovered that a PoS agent had used the IDs of 25 unsuspecting customers to activate 25 mobile numbers. That PoS agent was put on a blacklist, and their association with the department was re-investigated. Identity theft in the digital era can be simple, with low tech methods of stealing ID information, as well as an abuse of access to such information, having devastating consequences.
India's Legal & Regulatory Response
It should be noted that the Indian legislature has made provisions that address the issues relating to the misuse of identity especially within the telecom sector. One such statutory provision is contained in the Telecommunications Act 2023. Section 42(3)(e) provides for penalization for acquiring of SIMs or other telecommunication identifiers through means of fraud, cheating or impersonation. Section 42(3)(c) on the other hand addresses the issue of tampering with the telecommunication identifiers. The Telecommunications Act, 2023 provides for an imprisonment of up to three years and/or fine of up to rupees fifty lakh or both for offences under section 42(3). The concept of abetment has been dealt with separately in section 42(6). Moreover, section 66C and 66D of the Information Technology Act 2000 might apply where the facts show that there has been identity theft and/or cheating by impersonation using computer resources.
Measures for prevention adopted by the Department of Telecommunications:
- Sanchar Saathi: Allows them to see which mobile connections are registered in their names and report the mobile connections that they did not get or need.
- ASTR (Artificial Intelligence and Facial Recognition Powered Solution for Telecom SIM Subscriber Verification): leverages analytics to detect suspicious mobile connections and to re-verify.
- SIM-binding directions: In November 2025, DoT issued directions for communicating apps to maintain a linkage with the SIM which has been issued to the user bearing the mobile number with a requirement of periodic logout from web sessions as well.
These measures are indicative of a commitment to enhancing accountability and traceability in the telecom industry in India.
Challenges and the Way Forward
Despite these measures, tackling SIM muling requires more than simply increasing the number of verification checks. First, accountability needs to be extended further out from the registered subscriber to the intermediaries and Point of Sale (PoS) agents who enable the fraudulent activations. Secondly, there is a need to have good monitoring systems in place to detect expensive bulk SIM acquisitions and suspicious SIM use activity. Third, citizens' awareness is a must.
Users need to be aware that an SIM registered in their name can cause legal and financial hassles if it is shared or rented out. Meanwhile, investigations need to differentiate between knowingly participating in a fraud scheme and the use of an individual's identity without his or her consent. A balanced approach needs to be a combination of better verification, responsible data management, timely reporting systems and the cooperation between telecom operators, law-enforcement and digital platforms.
Conclusion
The existence of SIM farms in India is one of the numerous security problems which have been affecting India. There are many security problems related to India, but SIM farms and the abuse of mobile connections often do not receive the attention they deserve. Although the users of digital communication devices view mobile numbers as yet another medium to communicate, there is so much more to them. A mobile number is more than that. It is the means of linking to the online activities and banking of the user. It is also a tool for connecting to online services. Therefore, this is an urgent need to take measures to combat SIM muling.
As any digital security initiative worth its name, the users are also important here. The users should never sell, rent or lend their SIM cards while service providers and the regulatory authorities must exercise more surveillance and supervision. What is important is that those people whose names were used improperly should not be treated as criminals without any evidence pointing at them, even if the SIM card is more than just a card. In fact, keeping it secure is essential for digital security.
