SIM Binding for WhatsApp and Telegram from 1 January 2027: Accounts May Stop Working Without the Registered SIM, Wi-Fi and Multi-Device Users Affected
As per media reports and Department of Telecommunications (DoT) directions, messaging apps like WhatsApp and Telegram must keep a user's account linked to an active, KYC-verified SIM. The compliance deadline is 31 December 2026, so the rule is expected to apply in practice from 1 January 2027.
What May Change
- If the registered SIM is removed, replaced or deactivated, the app will stop working until a valid SIM is back.
- People who use chat apps only on Wi-Fi without a SIM may be directly affected.
- WhatsApp Web and linked devices may need to be reconnected.
Latest Update
- DoT issued the directions on 28 November 2025; the deadline was later extended to 31 December 2026.
- Reports say the earlier rule of logging out web sessions every 6 hours has been dropped.
- Apple reportedly added SIM-detection support in a September 2026 iOS update, and WhatsApp is reported to be beta testing on Android.
- There is no confirmed list of phone models on which WhatsApp will stop working.
What You Should Do
- Keep your SIM active with regular recharge or usage.
- Check with your operator that the KYC details for your number are correct.
- Before travelling abroad or using the app on another device, check the app's official announcement.
