Context
The Department of Telecommunications (DoT) has directed messaging platforms such as WhatsApp, Telegram, Signal, Snapchat, ShareChat and others to mandatorily link user accounts to the SIM card used during registration, a process called SIM binding. Users cannot access these services without the registered SIM in the device, and web versions will log out every six hours, raising concerns about privacy, usability, and access across multiple devices and during international travel.
What is SIM Binding?
- SIM binding means continuously linking a user’s messaging application to the SIM card used during registration.
- If the registered SIM is removed, switched, deactivated, or replaced, the user will lose access to the messaging application.
- At present, platforms verify users through a one-time password (OTP) at registration, after which the application continues to work even without the SIM.
- Under the new rule, apps will have to access IMSI (International Mobile Subscriber Identity) to verify the SIM continuously.
Why is SIM Binding Introduced?
The directive aims to prevent cyber fraud and scams where criminals:
- Use apps like WhatsApp remotely without a SIM in the device,
- Access accounts from outside India,
- Use SIM cards obtained illegally or through forged or mule identities.
The government expects greater traceability and accountability for digital communication platforms.
What the Directive Requires?
- Messaging platforms must ensure SIM-linked continuous access to their services within 90 days.
- Web portals like WhatsApp Web must log out automatically every six hours.
- Platforms must send a compliance report within four months.
- The directive draws power from the Telecommunication Cybersecurity Amendment Rules, 2025.
- The rule introduces the concept of TIUE (Telecommunication Identifier User Entity), meaning any entity that uses telecom identifiers such as mobile numbers to identify its users.
Implications of the SIM Binding Rule
- Accountability and traceability in cybercrime cases may improve.
- May reduce identity misuse, hacking, and impersonation fraud.
- Platforms like WhatsApp (with 500+ million users in India) must re-engineer systems specifically for Indian regulation.
- There may be a major impact on working professionals who depend on WhatsApp Web for productivity.
Concerns and Challenges Raised
- Users travelling abroad may lose access if they switch to a foreign SIM card.
- Users with multiple devices (phone + laptop + iPad) may face disruptions.
- Privacy issues arise as platforms must access IMSI and link accounts more tightly to telecom identity.
- People using services for work may face friction, as auto-logout interrupts workflow.
- Cybercriminals may still bypass rules using fake KYC SIMs, raising questions about effectiveness.
- Lack of clarity exists regarding SIM upgrades (4G to 5G), lost SIM, device change, or damaged SIM replacement.
Challenges and Way Forward
| Challenges | Way Forward |
| Disruption for travellers when switching to foreign SIM cards | Provide temporary exceptions or secure alternative verification options |
| Multiple-device use becomes difficult due to frequent logouts | Increase logout window and improve secure multi-device authentication |
| Privacy concerns due to continuous tracking through IMSI | Ensure strict data protection rules, transparency, and independent audits |
| Unclear process during SIM replacement or upgrade | Formulate clear guidelines for SIM change, damaged SIM, or device switch |
| Cyber fraud may continue due to fake SIM cards | Strengthen KYC verification and SIM issuing process, crack down on mule identities |
| Technical redesign required for global platforms | Provide transition support and allow phased implementation |
| Friction in professional use due to 6-hour logout limit | Extend logout time and create work mode flexibility features |
Conclusion
The SIM binding directive seeks to improve cybersecurity, accountability, and fraud prevention, but it also raises serious concerns about privacy, user convenience, international travel, and multi-device accessibility. A balanced approach is required where security improvements are matched with user rights, data protection, and practical implementation clarity.

| Ensure IAS Prelims Question Q. Consider the following statements regarding SIM binding introduced under the Telecommunication Cybersecurity Amendment Rules, 2025: 1. SIM binding requires messaging apps to remain continuously linked to the SIM card used during registration. 2. Under SIM binding, web versions of messaging services must be logged out periodically, not later than six hours. 3. SIM binding allows users to continue using messaging apps even if the registered SIM is removed or deactivated. Which of the statements given above is/are correct? a) 1 and 2 only b) 1 and 3 only c) 2 and 3 only d) 1, 2 and 3 Answer: a) 1 and 2 only Explanation Statement 1 is correct: SIM binding requires continuous linkage of a messaging platform to the SIM used during registration, and access must stop if the SIM is not present in the device. Statement 2 is correct: The directive requires associated web services such as WhatsApp Web to automatically log out every six hours to prevent misuse across devices. Statement 3 is incorrect: SIM binding prevents continued access when the SIM is removed or switched; users must re-verify identity. |
