WhatsApp to stop working for these users from Jan

whatsapp, telegram news — WhatsApp, Telegram SIM-binding rules may take effect from January 1, 2027. Know the deadline, who could be affected and what users should do.

WhatsApp and Telegram users who access their accounts without keeping the registered SIM card in their phones may have to change how they use the messaging apps from January 1, 2027. The Department of Telecommunications (DoT) has set December 31, 2026, as the deadline for messaging platforms to comply with SIM-binding requirements, a TOI report stated. The move is aimed at preventing cyber fraud and curbing the misuse of Indian mobile numbers by fraudsters.

Under the proposed requirements, messaging apps linked to Indian mobile numbers will need to ensure that the registered number is associated with an active SIM card or eSIM on the device. Users could face restrictions if the linked SIM is removed, deactivated or replaced and the app can no longer verify the number. This could affect people who use WhatsApp on a secondary phone, rely on Wi-Fi for most of their communication or remove their SIM card after setting up an account. However, the actual impact will depend on how individual platforms implement the requirements.

Why is the government introducing SIM-binding rules?

The DoT's move is part of a broader effort to tackle cybercrime, including phishing, online financial fraud and digital arrest scams. According to the concerns raised by authorities, fraudsters have exploited Indian mobile numbers to create messaging accounts and then operated those accounts from outside the country. Such accounts can be used to contact victims, impersonate officials or carry out fraudulent schemes.

The government believes that linking messaging accounts more closely to active SIM cards could make it harder for criminal networks to misuse Indian numbers. Cyber fraud has caused significant financial losses for consumers in India, prompting authorities to explore tighter checks on digital communication services. SIM-binding is intended to strengthen the link between a phone number and the device on which the associated messaging account is used.

Will WhatsApp and Telegram stop working without a SIM card?

Users could face account restrictions if their registered number does not meet the new verification requirements. However, this does not necessarily mean that every account will stop working immediately after a SIM card is removed. The precise consequences will depend on the final implementation and the verification mechanisms used by each platform. Users should therefore avoid assuming that an existing account will continue to work indefinitely without access to its registered number.

WhatsApp and Telegram are among the services expected to be affected because they use phone numbers for registration or account identification. Reports have suggested that Snapchat may not fall under the same requirement, while Signal's position has remained unclear. The coverage of individual platforms should be confirmed through official announcements as implementation details become available.

Whatsapp new rule: Which users could be affected?

The proposed rules could have implications for several common ways of using messaging apps.

People using WhatsApp on a secondary phone: Some users keep their registered SIM in one handset but access WhatsApp on another device. They may need to check whether their setup meets the platform's requirements.

Users who remove their SIM after registration: Those who take out their registered SIM once an account is activated could face problems if the app requires the SIM to be present for verification.

Wi-Fi-only users: People who primarily use messaging apps over Wi-Fi may need to ensure that their registered number remains active and meets the new conditions.

Dual-SIM phone users: Those with two numbers in one handset should check which number is linked to their messaging account and whether that number remains active.

Will eSIM users be affected?

The requirements are expected to cover both physical SIM cards and eSIM profiles. An eSIM is a digital SIM that allows a compatible phone to connect to a mobile network without a removable SIM card. Users who have their registered number active through an eSIM may be able to meet the requirements without inserting a physical SIM.

However, having an eSIM alone may not guarantee compliance in every situation. Users should check the final rules and the guidance issued by their messaging platform.

Will WhatsApp stop working on older iPhones or Android phones?

The proposed SIM-binding requirements are about mobile-number verification, not about specific phone brands or operating systems. There is no indication in the information available so far that WhatsApp will stop working on particular iPhone or Android models from January 1, 2027, because of this mandate. Device compatibility is a separate issue from whether an account meets SIM-binding requirements.

What should WhatsApp and Telegram users do before January 1, 2027?

Users can take a few practical steps to prepare for the proposed changes.

Keep the registered number active: Avoid allowing the SIM linked to your account to become inactive.
Check your linked number: Make sure you know which mobile number was used to register your account.
Review secondary-device use: If you access the account on another phone or device, look out for platform-specific instructions.
Check eSIM support: If you use an eSIM, confirm that the registered number remains active and that your device supports the required configuration.
Watch for official updates: Follow announcements from the DoT and the messaging platforms for details on verification, enforcement and possible exceptions.
