Connects AI agents to real SIM phone numbers across 145+ countries for SMS verification and OTP receiving. Exposes 18 tools including find_cheapest, wait_for_code, search_service, and swap_number. Supports both stdio and StreamableHTTP transports, with a hosted endpoint at mcp.virtualsms.io that requires zero local setup. Built on physical modem infrastructure, not VoIP, so numbers work with services that block virtual numbers like WhatsApp and banking apps. Covers 2500+ services including Telegram, Google, Instagram, and Uber. Useful when building agents that need to autonomously verify accounts or receive SMS codes. Pricing starts at $0.02 per number with WebSocket push for real-time delivery.
