WhatsApp is India's primary communication tool — for personal calls, client meetings, and business coordination. But many Indian ISPs throttle VoIP traffic during peak hours, causing dropped calls, poor audio quality, and frozen video. A VPN encrypts your traffic so your ISP can't identify and throttle WhatsApp calls.
