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
