WhatsApp faces significant challenges in India, its largest market, as the government imposes regulations requiring messaging apps to remain linked to a SIM card. This directive aims to combat rising cyber fraud, with losses exceeding ₹228 billion ($2.5 billion) in 2024. Experts warn that such measures may disrupt normal operations for over 500 million WhatsApp users, especially small businesses relying on its communication platform, risking long-term disruptions in service delivery.
