WhatsApp & Telegram Update: DoT’s New SIM-Binding Rule, Auto Logout Every 6 Hours

India’s new SIM-binding regulation is set to change how messaging apps like WhatsApp and Telegram are used. Under this rule:

• These apps will only work on the phone where the registered SIM is active.

• If the SIM is removed or changed, app access will be blocked immediately.

• WhatsApp Web will auto-log out every 6 hours, reducing the risk of unauthorized access on unknown devices.

Why the Change?

The government introduced this step to tackle:

• Rising SIM frauds

• Cybercrime

• Misuse of messaging apps

Who Will Be Affected?

This will particularly impact:

• Office users

• Dual-SIM phone owners

• Multi-device setups

• Travelers going abroad

After the update, users will need to keep the registered SIM active to continue using these messaging apps.
