India's new rule: Messaging apps must work only with active SIM cards

Technology Nov 29, 2025

India is rolling out a new rule for apps like WhatsApp and Telegram—soon, you'll only be able to use them if your SIM card is active.
The government says this is to stop cybercriminals from misusing Indian mobile numbers, and the change kicks in within 90 days.

What this means for you

Messaging apps will now check regularly if your SIM card is still inserted. If you remove your SIM, the app stops working until it's back in.
Telecom companies support the move, arguing it will improve verification and reduce misuse. But experts warn it might not fully stop fraud using fake or temporary SIMs.
Also, get ready for more frequent logins—especially if you use these apps on web browsers or secondary devices without a SIM.
