Answer: SAMBHAV
Notes: During Operation Sindoor, the Indian Army used its indigenous M-Sigma app on SAMBHAV (Secure Army Mobile Bharat Version) smartphones for secure communication. SAMBHAV replaced foreign apps like WhatsApp to prevent external surveillance. The system was launched in 2023 as India’s first fully indigenous secure mobile communication ecosystem. It supports 5G connectivity, multi-tier encryption, and network-agnostic operation for real-time secure communication. M-Sigma allows soldiers to exchange images, videos, and files safely. Nearly 30,000 SAMBHAV-enabled handsets were deployed by early 2024 among army officers. It was also used during military-level talks with China, ensuring secure diplomacy.
