Messaging giant whatsapp is reportedly testing a new SIM‑binding feature that could make the app stop working if an active SIM card — the one used to register the account — is not present in the device. This move comes as part of India’s effort to enforce tighter security and anti‑fraud rules on messaging platforms.

🛂 Why india Introduced the New Rules

India’s Department of Telecommunications (DoT) has issued a directive to messaging platforms, including whatsapp, requiring them to remain linked to a user’s active SIM card at all times. This is part of the Telecommunications (Telecom Cyber Security) Rules, 2024 aimed at preventing fraud, misuse of numbers, and fake accounts.

Under the old system, once a user verified their mobile number during setup using a one‑time code (OTP), whatsapp would let them continue using the app even if the SIM was removed. The new rules seek to change this by making continuous SIM presence mandatory.

🔍 How the SIM‑Binding Feature Works

According to reports from beta versions of WhatsApp’s Android app, the platform is building a feature that periodically checks whether the registered SIM card is physically present and active in the phone. If the app detects that the SIM is missing or does not match the registered number, it may limit access to the account until the SIM is verified again.

Here’s what this could mean in practice:

• 📵 WhatsApp might stop working if the SIM is removed or becomes inactive.
• 📬 You might not receive new messages until the SIM is verified.
• 📄 Your existing chats and history are expected to remain safe even if access is restricted.

This feature is currently under development and hasn’t rolled out globally yet.

🪪 What “Active SIM” Really Means

An “active SIM” in this context refers to the physical SIM card linked to your whatsapp number that is currently installed in your device and not deactivated or removed. If your SIM becomes inactive (for example, due to lack of recharge) or is replaced, whatsapp may stop functioning until verification is successful.

This is similar to how UPI apps in India already require users to have an active SIM to use payment services.

🕐 Additional Requirements for Web/Desktop Users

Under the same regulatory directive, platforms must also make web or desktop versions of messaging apps log out automatically every six hours, requiring users to reauthenticate via QR code. This is meant to ensure ongoing verification across devices.

🌍 Who Will Be Affected?

These rules are specific to users with Indian phone numbers (+91). Users outside india are expected to continue using whatsapp without the periodic SIM checks, as the regulations apply only within indian jurisdiction.

⚠️ Concerns and Criticisms

While the government says these measures will improve security and reduce fraud, critics argue they could make whatsapp more difficult to use in situations like:

• Travelling abroad or switching phones temporarily
• Using multi‑device setups without the SIM inserted
• Cases where SIM cards are lost, damaged or under repair

Some tech groups have also raised concerns about how these rules were formulated and whether they adequately consider user experience and device diversity.

📅 Implementation Timeline

DoT first issued the SIM‑binding directive in November 2025, and companies have been given a compliance window to implement these changes. WhatsApp’s beta tests suggest the feature is in development, but an official launch date hasn’t been confirmed.

🧠 Bottom Line

WhatsApp may soon require users in india to keep their registered SIM card active and present in the device to continue using the app. This is part of a broader push by indian authorities to tighten verification and reduce fraud on communication platforms. While it promises greater security, the shift could change how people use whatsapp, especially those who rely on SIM‑less access or multi‑device setups.
