VirtualSMS Reviews & Product Details

VirtualSMS is an SMS verification API that provides phone numbers from 145+ countries for receiving OTP codes. The service uses real SIM-backed phone numbers rather than VoIP, enabling verification on services that reject VoIP numbers including WhatsApp Business, Telegram, banking applications, and dating platforms. The platform offers a REST API with OpenAPI 3.1 specification, webhooks for asynchronous event notifications, WebSocket for real-time SMS delivery, and a Model Context Protocol (MCP) server for integration with AI agents such as Claude, Cursor, and ChatGPT. A legacy compatibility endpoint at /stubs/handler_api.php replicates the sms-activate API format, enabling migration from older providers without code changes beyond the base URL. Pricing is pay-per-use starting at $0.05 per OTP code, with no contracts, no minimum deposits, and automatic refunds on failed delivery. Payment options include credit cards, cryptocurrency (BEP20), and x402 stablecoin protocol on Base, Polygon, Arbitrum, and Optimism networks. Coverage includes 2,500+ services including WhatsApp, Telegram, Discord, Gmail, Snapchat, Tinder, banking applications, and e-commerce platforms. SDKs are available for PHP via Composer and a Node.js npm package for the MCP server. A free public price endpoint allows pricing queries without authentication.
