New Telecom Rules 2025: WhatsApp, Telegram Must Have Active SIM, Auto Logout Feature Every 6 Hours

WhatsApp Will No Longer Work Without an Active SIM? New Rule Brings Major Changes

The Indian government has introduced a major regulatory shift that will directly affect users of WhatsApp, Telegram, Snapchat, ShareChat, JioChat and several other messaging platforms. As per the newly announced Telecommunication Cybersecurity Amendment Rules 2025, all messaging apps must now be mandatorily linked with an active SIM card, similar to telecom services. Once the SIM is removed from the device, the app will automatically stop functioning.

Under these new rules, messaging platforms will be required to implement this system within the next 90 days. The government believes that this decision is critical for tackling cybercrime, online fraud, and international scam networks that exploit loopholes in mobile-based messaging services.

Key Highlights of the New Rule

The Telecom Department (DoT) has outlined several mandatory requirements:

• Apps must ensure that the user’s SIM card remains continuously active in the device.

• If the SIM is removed, switched off, blocked, or replaced, the messaging app must immediately stop working.

• For users accessing platforms like WhatsApp Web, the government has introduced a big change:
  Web sessions will automatically log out every 6 hours, requiring QR code re-verification each time.

• All app-based communication platforms must implement the SIM binding mechanism within 90 days.

The government says these steps will significantly enhance user identity verification and reduce illegal activities executed through anonymous or unverified mobile numbers.

Why Was This Decision Taken?

According to the DoT, the current verification system used by messaging apps is highly vulnerable. Although mobile numbers are authenticated during account registration, apps continue to function even if the SIM is removed from the device. This loophole, authorities claim, enables scammers to run fraudulent operations using temporary or foreign phone numbers without being traced.

The Cellular Operators Association of India (COAI) supports the new regulation, stating that continuous SIM-device binding will improve traceability between the user, the device, and the mobile number, similar to bank or UPI applications that already follow strict verification protocols.

The government also believes that this rule will help fight:

• Financial frauds

• International scam networks

• Identity spoofing

• Spam accounts and fake numbers

• Cybersecurity breaches

Will SIM Binding Really Strengthen Security?

The expert community is divided over the impact of these new telecom cybersecurity rules.

Supportive experts argue:

• Fraud and digital scams will significantly reduce.

• Every active account will always remain SIM-verified.

• Identifying offenders will become easier for law-enforcement agencies.

Concerns raised by critics:

• Fake or illegally issued SIM cards are still widely accessible, which could allow scammers to bypass the system.

• Re-verification every 6 hours on web login could be extremely inconvenient for users who access messaging apps for work purposes.

• Questions are being raised about privacy and data surveillance.

• Frequent logout sessions will disrupt workflow for millions of users who rely on WhatsApp Web for business communication.

The biggest inconvenience, users say, is that WhatsApp Web will no longer stay logged in for 24 hours or more, which may cause challenges for offices and remote professionals.

What Users Can Expect Next

Messaging platforms now have three months to redesign their systems and comply with the new cybersecurity guidelines. If implemented strictly, the rule will impact:

• Business accounts operating through desktop interfaces

• People who frequently change devices or SIM cards

• Multi-device access users

• Remote working professionals relying on long web sessions

While the goal behind the rule is to improve national cybersecurity, it remains to be seen whether it will effectively reduce fraud or create additional hurdles for genuine users.

Stay tuned for more updates on implementation timelines and how WhatsApp and other messaging platforms respond to these new telecom regulations.
