India may log you out of WhatsApp if your SIM card is removed

WhatsApp and Telegram users in India could lose access to their accounts if the SIM card they signed up with is no longer in their phone. India's Department of Telecommunications (DoT) has set December 31, 2026 as the deadline for messaging apps to comply. The rules could take effect from January 1, 2027.

What changed

Messaging apps that use Indian mobile numbers to register accounts will have to confirm that the number is tied to an active SIM card or eSIM on the device. This is called SIM binding. An eSIM is a digital SIM built into the phone, with no physical card.

In practice, you may no longer be able to keep using an account forever after taking out the SIM you used to create it. If the registered SIM is removed, replaced or becomes inactive, the app could suspend the account until the same number is restored through a valid SIM or eSIM profile.

Why the rule exists

The government says this is part of a push against cybercrime, phishing and so-called digital arrest scams. According to the DoT, fraud networks buy SIM cards, register messaging accounts, then run those accounts from outside India. Officials believe tighter links between accounts and active SIMs will make that harder. The government also points to large financial losses suffered by Indian consumers from cyber fraud in recent years.

Who it affects

WhatsApp and Telegram are expected to fall under the rules because they use phone numbers to identify users. The biggest impact may be on these groups:

• People who keep the registered SIM in a second phone and use WhatsApp on another device
• People who remove the SIM after setting up their account
• People who rely mostly on Wi-Fi and rarely use cellular service
• Dual-SIM users, who may need to make sure the linked number stays active

The rules are expected to cover both physical SIM cards and eSIMs. If your registered number is tied to an active eSIM on the device, you are unlikely to run into trouble just because you have no physical SIM.

What is not affected

Nothing so far suggests WhatsApp will stop working on certain iPhone or Android models on January 1, 2027. The restrictions are about SIM checks and account sign-in, not phone brands or operating systems. Reports say Snapchat is not expected to be covered.

What is still unclear

Signal's status is unknown. Reports suggest it had not responded to government communications when the issue was reviewed. The material also does not say how often apps will check your SIM or how long you would have before an account is suspended.

For now, the safe move is to keep the number you registered with active on the phone where you use the app.
