The Government of India (GoI) is likely extending the deadline for mandatory SIM binding for messaging platforms, such as WhatsApp, Arattai, and Telegram. The Department of Telecommunications (DoT) is expected to give a deadline of December 2026 to companies to comply with this directive.
As per a report from Hindustan Times, the department is planning to extend the deadline following requests from companies, citing technical challenges. Here is what this means for you.
What is SIM binding?
In November 2025, the government had notified app-based communication platforms such as WhatsApp, that use mobile numbers for user identification to ensure their services remain linked to the SIM card installed in the user’s device. The initial deadline for the mandate was set for March 1, 2026.
That is, a user will be able to access their account on the platform only if the registered SIM card is in the device they are using. This measure aims to prevent misuse of telecom identifiers, including cyber fraud originating from outside India.
A similar SIM binding mandate is already followed by banking and payment apps such as Google Pay.
For linked devices, or web-based versions of the app, such as WhatsApp web, the directive stated that users would be logged out every six hours. A user must re-authenticate after being logged out to use the web version again.
Why is SIM binding for messaging apps delayed?
As per the report, companies faced technical challenges in implementing the directive requirements. A DoT official told Hindustan Times, “We will extend the compliance deadlines as companies have run into technical challenges, including testing and operating system updates.”
As per the official, the rollout will be done in a phased manner, with Android devices meeting the directive first. Apple is reportedly working to resolve certain iOS constraints that will allow messaging apps on iOS to comply.
Under the original timeline, companies were to comply within 90 days of the directive and submit reports within 120 days, with the compliance deadline set for the end of February. Companies were unable to meet this deadline.
The directive has faced pushback over practical difficulties and potential impacts on user experience. Enforcing continuous SIM binding across multiple devices and web logins requires significant app architecture changes and coordination with operating system providers.
WhatsApp begins SIM binding on Android
WhatsApp’s parent company, Meta, is working with the DoT to find a feasible solution. SIM binding on WhatsApp is currently in a beta phase on Android.
Zoho, the company behind India’s homegrown messaging app Arattai, is also working on complying to the directive. Arattai’s global product head, Jeri John, stated, “They have granted us a grace period, and we will roll out the necessary updates in the coming weeks to ensure full compliance with the directive.”
Officials believe that this directive is necessary to curb cyber fraud, with losses in 2024 surpassing Rs 22,800 crore. The government aims to ensure accounts remain linked to KYC-verified SIMs physically present in devices, improving traceability and reducing fraud risks.
