What is the Sanchar Saathi app, which India has mandated be preloaded on phones?
Sanchar Saathi is a government-owned cyber safety app for users to report fraud communications via calls, SMS or WhatsApp. It allows users to track/block stolen/lost phones' IMEI numbers, verify if their purchased mobile device is genuine and report international calls disguised as domestic calls from numbers starting with '+91'. It also offers the 'Know your Internet Service Provider' feature.
