For travelers, individuals, and businesses comparing communication options. The plugin offers four read-only tools: search_virtual_numbers, list_esim_plans, get_service_pricing, and get_call_rates. It does not reserve or purchase numbers, order or activate eSIMs, place calls, send messages, or access private account information. If live number availability cannot be retrieved, it returns an unavailable status instead of invented inventory. Prices are in USD; confirm final availability, compatibility, taxes, and purchase terms on the VoxTelefony website.",
