WhatsApp is one of the most popular messaging apps in the world, but in some countries, calling features are blocked. A VPN for WhatsApp can let you bypass government firewalls and ISP restrictions. The best VPNs for WhatsApp offer no-logs policies, VoIP-friendly connections, and servers optimized for restricted countries. Whether you're trying to call family overseas, conduct business, or just stay in touch while traveling, a VPN ensures that WhatsApp runs smoothly and securely. If you're seeing errors like "WhatsApp call not available" or "call blocked in your region," using a VPN is the easiest fix.
