Messaging apps such as WhatsApp and Telegram may face access restrictions in India from January 1, 2027, if users do not keep the SIM card linked to their accounts active and available in their devices. The Department of Telecommunications (DoT) has directed covered messaging platforms to implement mandatory SIM-binding requirements by December 31, 2026.

The rules are intended to prevent the misuse of Indian mobile numbers for cybercrime, including phishing, impersonation and digital arrest scams. The government has raised concerns about fraudsters registering accounts using Indian SIM cards and then operating those accounts from overseas, even when the original SIM is no longer present in the device.
What Is SIM Binding?
SIM binding links a messaging account to the active SIM or eSIM associated with its registered mobile number. Under the rules, covered apps may restrict access if the registered SIM is removed, replaced or deactivated. Users who run WhatsApp or Telegram on a phone without the registered SIM could be affected.
Which Apps Could Be Affected?
The directive covers services including WhatsApp, Telegram, Signal, Snapchat, ShareChat, JioChat, Arattai and Josh. The precise implementation may vary by platform, and users should follow official app notifications for specific instructions.
Why Is the Government Introducing This Rule?
The government says SIM binding will make it harder for fraudsters to operate messaging accounts using Indian numbers without access to the registered SIM. The measure is intended to improve traceability and reduce phishing, impersonation and digital arrest scams.
What Should Users Do?
- Keep the SIM or eSIM linked to your messaging account active on the device where you use the app.
- Check your setup if you use messaging apps on a Wi-Fi-only phone or across multiple devices.
- Watch for official app notifications about SIM verification and compliance.
The rules are scheduled to take effect from January 1, 2027, with platforms expected to meet the compliance deadline by December 31, 2026. The change does not mean every user will automatically lose access; the impact will depend on whether the registered SIM is available and can be verified.
