WhatsApp, Meta’s vital messaging tool for millions of Indians, faces a regulatory storm in its largest market. New government orders could disrupt core features, hitting users and businesses hard.

Issued late November and published soon after, the rules force major apps to bind accounts to active SIMs and require six-hourly QR re-logins for web/desktop use. New Delhi aims to curb cyber fraud in its 1.4 billion population, after ₹228 billion losses in 2024.

“Mandatory continuous SIM–device binding and periodic logout ensure that every active account and web session is anchored to a live, KYC-verified SIM, restoring traceability of numbers used in phishing, investment, digital arrest, and loan scams,” the telecom ministry said.

Roamers are exempt if SIMs stay inserted. WhatsApp, with over 500 million users, sees 94% daily opens among Indians (67% Business) per Sensor Tower—beating U.S. rates of 59% and 57%.

Traders rely on WhatsApp Business via multi-device setups, clashing with rules that undo 

multi-device and iPad advances. Growth now stems from retention: Q4 actives up 6% year-on-year despite 49% download drops, per Sensor Tower.

“It could be fair to say that user (MAU) growth for WhatsApp in India across the past few years has been driven more by retention (successfully re-engaging existing or previous users) than acquiring new users,” said Abraham Yousef of Sensor Tower.

Business activities surged 130% since 2021, fuelling merchant adoption amid dual-SIM habits. Indians average 38 daily minutes on the app, inverting U.S. patterns.

Broadband India Forum warned of “material inconvenience and service disruption” and “serious questions of technical feasibility.” Kazim Rizvi of The Dialogue criticised the TIUEs classification as delegated overreach.

“The directions derive their power not from statute but from delegated legislation,” Rizvi told TechCrunch. “Moreover, the lack of public consultations or technical working groups risks creating compliance friction without addressing the underlying fraud vectors.”

Legal challenges face high hurdles, per experts like Dhruv Garg. PwC notes apps drive 40% of small business deals as fraud rises.
