1. 🧠 What’s the New Rule All About?

The Department of Telecommunications (DoT) in india has issued a directive under the Telecommunication Cybersecurity Rules that messaging platforms like WhatsApp, Telegram, Signal, Snapchat and others must stay continuously linked to the SIM card used during registration. If the SIM isn’t present and active in the device, the app must stop working.

2. 📅 Effective from february 2026

Messaging apps will have about 90 days to implement this “SIM‑binding” feature. From February 2026, users may face restrictions unless their device contains the same active SIM originally used to set up the app.

3. 📵 What Happens If Your SIM Isn’t in the Device?

  • The app may stop working if the registered SIM is removed or deactivated.
  • This affects everyday uses like switching SIM cards, using local SIMs abroad, or using apps on devices without a SIM (like tablets).

4. 💻 WhatsApp Web & Desktop Will Auto‑Logout

Even on computers or web browsers, you won’t stay logged in forever. Sessions must automatically log out every six hours, and you’ll need to rescan the QR code from your phone to reconnect.

5. 🤔 Why the government Is Doing This

Authorities say the rule aims to curb cyber fraud and impersonation scams by tying messaging accounts more closely to verified mobile subscribers, making misuse and anonymous accounts harder to maintain.

6. 🔄 How This Affects You Personally

  • 📱 Multi‑device use (phones, tablets) becomes trickier.
  • 🌍 Travelers using foreign SIMs may be locked out if the original SIM isn’t present.
  • 🖥️ Work setups with whatsapp Web or Telegram Desktop will need frequent logins.
  • 📲 Users who swap SIMs often may experience service interruptions.

7. 🧠 Industry Concerns & Reactions

Tech and telecom stakeholders have raised concerns that such rules could inconvenience legitimate users and that enforcing SIM‑binding across apps may be technically complex. Critics also argue that it may not fully stop fraud if scammers use forged or stolen SIMs.

📌 Bottom Line

From February 2026, your favourite messaging apps won’t just rely on a one‑time number verification — they’ll constantly check that your active, registered SIM is in your device. If it isn’t, services could stop working or force frequent re‑authentication.
