Unlike Signal or WhatsApp, Lumen Mesh requires zero infrastructure—no internet, no SIM, no servers. It turns your smartphone into a permanent, self-healing node. What stands out: 24/7 Background Engine: While other mesh apps fail when minimized, Lumen PRO keeps the mesh alive in your pocket. Stealth Mode: Signal masking for professional privacy. Custom Mesh Keys: Create isolated, private sub-networks. Zero Metadata: No server exists to track your connections.
