What are SIM binding directives?
DoT had issued the SIM binding directive in November 2025, requiring messaging platforms that use mobile numbers for user identification to ensure their services are linked to the SIM card installed in the user’s device. The aim is to make it harder to use such apps without an active SIM, helping plug security gaps that have been exploited for digital fraud.
Deadline likely to be extended
According to Hindustan Times, a DoT official said the government will extend compliance deadlines as companies have faced issues related to testing and operating system updates.
“We will extend the compliance deadlines as companies have run into technical challenges… The compliance will happen in a phased manner,” the official said, as quoted by Hindustan Times.
The report added that Android devices are likely to comply first, while iOS is facing certain constraints.
Missed timelines and industry response
The companies were initially required to comply within 90 days of the November 2025 directive, setting a deadline of February-end 2026. However, these timelines were not met. The report noted that while DoT had earlier indicated flexibility until March-end, it is now considering a longer extension after requests from platforms.
As per the report, Meta said that the company is working with DoT to find a technically feasible solution. Meanwhile, SIM binding for WhatsApp on Android is reportedly in beta testing.”
