Q. Which one of the following statements best describes the meaning of SIM Binding?

[A] A process of linking over-the-top (OTT) communication apps continuously with the mobile SIM card to ensure user accountability and prevent misuse.

[B] A method of enabling multiple SIM cards to be used on a single device without restrictions.

[C] An authentication technique used only during the initial registration of telecommunication services.

[D] A system that anonymizes SIM card information to protect user privacy on communication apps.

Answer: A
Notes:

Explanation:     

  • SIM Binding is a regulatory measure mandated by the Indian Department of Telecommunications requiring OTT apps like WhatsApp and Telegram to remain continuously linked to a verified SIM card in the device. This helps in reducing online fraud, ensuring traceability, and enhancing cybersecurity. The linkage is not a one-time process but persistent so that the app stops functioning if the SIM is removed, replaced, or deactivated.
