VirtualSMS

What is VirtualSMS?

VirtualSMS is a real-SIM phone verification platform built for AI agents and developers. The MCP server (installable in Claude, Cursor, Codex, Windsurf, and 6 other clients) exposes 18 tools for ordering numbers, checking stock, polling for SMS codes, and managing balance. Agents pay via REST API deposit (multi-chain crypto, $2 minimum) or x402 micropayments on Base + Solana. Numbers are genuine carrier SIM cards across 145+ countries — not VoIP — so they pass HLR lookups and verify cleanly on services that block disposable numbers (WhatsApp, Telegram, Discord, Gmail). Used by autonomous agents to verify accounts, complete signup flows, or rent long-term numbers without exposing operator phone numbers. From $0.05/activation; 2,500+ services
