New Delhi: The Department of Telecommunications (DoT) has tightened SIM-binding rules for all OTT communication apps operating in India. According to an order issued on November 28, 2025, messaging platforms such as WhatsApp, Telegram, Signal, Arattai, Snapchat, ShareChat, JioChat, and Josh must ensure within the next 90 days that user accounts remain linked to the same SIM and mobile number used during initial registration.
Key Directives
- Apps will not function on a device if the registered SIM is not continuously present.
- For apps supporting multiple devices per account, all linked devices must automatically log out every six hours. Users will then need to scan a QR code to log in again.
- All Telecom Identifier User Entities (TIUEs) are required to comply with these directives and submit compliance reports within 120 days.
Impact on Users and Industry
Industry experts warn that the new regulations could reduce the active user base of major messaging apps. The rules may pose significant technical and financial challenges, especially for users in rural areas or those with limited data access.
Indian users traveling abroad may find their numbers automatically deactivated. Multi-device logouts every six hours could disrupt operations for businesses using office or laptop devices. Users in rural regions may face difficulties creating or maintaining accounts due to data costs. A senior telecom executive commented,
“The intent is positive, but implementation will be technically challenging. Rural and data-sensitive users will be most affected.”
DoT’s Objective
The primary goal of SIM-binding is to curb misuse of telecom identities, devices, networks, and services while strengthening cybersecurity. The move aligns with the DoT’s efforts to safeguard growing digital communications in India.
Earlier, amended telecom cybersecurity rules provided similar directives, but the new order adds stricter conditions, including six-hour logouts and mandatory compliance reporting, making enforcement more rigorous.
Expert Opinion
Telecom and digital communication specialists believe the measures will enhance cybersecurity and ensure authentic user identification. However, many users may face challenges due to technical constraints and additional data costs. Multi-device account users, businesses, and rural communities are expected to feel the most direct impact.
Industry Consequences
Analysts anticipate a potential decline in active users on platforms like WhatsApp, Telegram, Signal, and Arattai. Indian users traveling overseas may experience automatic number deactivation, while frequent logouts on office devices could hamper business workflows.
