WhatsApp, Telegram SIM binding rules from January 1, 2027: Who will be affected in India?
WhatsApp, Telegram and other messaging apps may face new access restrictions in India as the government prepares to implement SIM-binding rules from January 1, 2027. The DoT has issued guidelines that require the covered platforms to integrate the accounts with the live SIMs used for the registration by December 31, 2026. The rules are to prevent cyber frauds using Indian mobile numbers.
The new regulation requires that the messaging services make sure accounts are associated with the registered SIM card that is installed in the device. This may impact the users of WhatsApp or Telegram over Wi-Fi without their registered SIM and those who use more than one device and who often change their SIM. The DoT has issued the directive on November 28, 2025, under the Telecom Cyber Security Rules. However, the precise impact on individual devices will depend on how platforms implement the requirements.
What is SIM binding, and why is the government introducing it?
Similar to the others, most messaging apps will use a one-time SMS code to verify your number. Users are usually able to retain the use of their accounts even if they remove or disable the SIM card. SIM binding is designed to overcome this by ensuring the SIM card is activated and in the device.
According to the Ministry of Communications, cybercriminals exploit this gap to conduct digital fraud, including scams involving callers impersonating government officials. Last year, the losses from cyber fraud accounted for more than ₹22,800 crore, the ministry said. The rules will enhance traceability and stop misuse of telecom identifiers, the government states.
Which messaging apps are covered by the new rules?
As per the order, the banned apps include WhatsApp, Telegram, Snapchat, Arattai, ShareChat, Josh, JioChat and Signal apps. The impact of WhatsApp’s user base in India, which is estimated to be in the range of 500 million users, could be significant.
It is possible that the compliance requirements and their implementation could vary between platforms. According to reports, WhatsApp has now started beta testing SIM binding on Android.
How will SIM binding affect WhatsApp Web and other devices?
Removing a registered SIM or disabling a number or sending messages from a device that doesn’t have a SIM may disrupt users. Additionally, people who travel overseas often or change their phones frequently or who only use Wi-Fi on their tablets may want to make adjustments as well.
The DoT has revised another part of the directive. The earlier idea of logging users out of Web sessions every six hours has been removed and replaced with a risk-based logout requirement. This translates to no more automatic logouts every six hours.
What happens if messaging apps fail to comply?
Platforms failing to comply with the requirements may be subject to the provisions of the Telecommunications Act, 2023 and the Telecom Cyber Security Rules, 2024.
According to a survey conducted by CUTS International, 80% of consumers and over 60% of small businesses were anticipating disruption due to SIM binding. DoT also intends to launch an MNV platform to verify phone numbers to ensure that they are belonging to authentic users.
It’s important for users to be aware that it’s reported as an operational start date (after the compliance date of December 31, 2026). The rules don’t say that all WhatsApp or Telegram accounts will no longer function on that day. The actual impact will depend on platform compliance and how SIM verification is enforced.
