Government Mandates SIM Binding for Messaging Apps: A Cybersecurity Measure or User Inconvenience?
A recent directive from the government requiring active SIM cards to be linked to messaging applications on personal devices has ignited considerable backlash across social media platforms.
Users are expressing their frustrations regarding the automatic logouts from web versions of these applications every six hours, necessitating re-authentication via QR code.
Although the changes may initially seem burdensome to users, reports indicate that the government’s decision is not only judicious but also timely.
The U.S. Cybersecurity and Infrastructure Security Agency (CISA) recently disclosed that hackers have been employing sophisticated spyware to target messaging accounts, including WhatsApp.
In a news alert issued last week, CISA revealed that cyber adversaries are utilizing “advanced targeting techniques and social engineering” to gain “unauthorized access” to users’ messaging applications, thereby facilitating the introduction of additional malicious payloads that can further jeopardize the victim’s mobile device.
CISA underscored that such intricate spyware attacks are not confined to high-profile targets; they pose threats to everyday consumers as well, manifesting through malicious links, QR codes, unauthorized app installations, mobile malware, and counterfeit applications masquerading as legitimate ones.
Alarmingly, it stated that 99% of defense hinges upon refraining from clicking dubious links and avoiding installations from unverified external sources.
Numerous articles published in the United States over the past week have specifically highlighted India’s recent policy initiatives regarding SIM binding, deeming them a pivotal measure to mitigate the risk associated with users relying on a single account linked to a SIM across multiple devices.
Although the re-verification process could be somewhat irksome, it ensures that WhatsApp is tethered to a mobile number, thereby enhancing security.
Overview of the New DoT Regulation and Its Implications
The recent notification from the Telecom Ministry stipulates that messaging services such as WhatsApp, Telegram, and Signal cannot function without an associated SIM card or with a different one. The government contends that this regulatory change aims to eliminate the risks of identity theft concerning customer data.
This directive follows prior notifications regarding Telecom Cyber Security Rules in 2024, with updates made in 2025. WhatsApp has now been classified as a Telecommunication Identifier User Entity (TIUE), which extends regulatory scrutiny beyond conventional mobile carriers.
This classification mandates that WhatsApp and similar services adhere to a series of cybersecurity and verification responsibilities akin to those imposed on telecom operators.
“The Subscriber Identity Module within the device hosting the App-Based Communication Services presents a challenge for telecom cybersecurity, as it is being exploited from outside the country to perpetrate cyber fraud,” stated the Department of Telecom.
The DoT also noted, “Discussions with key service providers have been ongoing for several months. In light of the gravity of the situation, it became essential to issue directives to App-Based Communication Services to prevent the misuse of telecommunication identifiers and to protect the integrity and security of the telecom ecosystem.”
What Changes Lie Ahead?
What specific alterations are being introduced by India’s SIM-binding regulations? Here are the key points:
- All app-based communication services must be linked to a SIM card within 90 days, rendering the use of the service impossible without that specific active SIM.
- During that same timeframe, web service instances of mobile apps (e.g., WhatsApp for Web) will log users out every six hours, requiring them to re-establish the connection via QR code.
- The DoT has mandated that these directions take immediate effect and remain active until revised or revoked.
- All applications must submit compliance reports to the DoT within 120 days of these directives, with non-compliance resulting in repercussions under the Telecom Act, 2023, and the Telecom Cyber Security Rules, 2024.
Rationale Behind the New Cybersecurity Regulations
According to sources within the ministry, these measures are designed to facilitate the government’s oversight of telecom fraud. A statement from the Cellular Operators Association of India (COAI) indicated that SIM binding occurs only once during the installation process, allowing the app to operate autonomously thereafter.
This creates potential opportunities for misuse, and regular SIM verification would effectively close this gap.
Officials emphasized that these modifications will assist in addressing the issue of global-scale scams, where fraudsters frequently exploit inactive or disconnected SIM cards from abroad to execute phishing attacks on Indian citizens, leading to financial fraud targeting their bank accounts.

Moreover, WhatsApp has cautioned users against sharing their registration codes, not even with acquaintances.
The Meta-owned messaging platform has clarified that it is unable to deactivate a user’s account on their behalf because verifying the ownership of the associated phone number is unfeasible.
This flaw is what the Indian administration aims to rectify. Thus, while the frequent logouts from the web version of WhatsApp may prove inconvenient, the new directives from the Department of Telecom align with a prudent approach to cybersecurity.
