VirtualSMS is a developer-first SMS verification API that uses real SIM-backed phone numbers, not VoIP. Receive OTP codes for any service that sends SMS โ€” built for signup testing, account verification, 2FA flows, and autonomous AI agent workflows.

Why VirtualSMS

  • Real SIM numbers work where VoIP fails. Most providers (5SIM, SMS-Activate, SMSPVA, Veritel, SMSPool) lean heavily on VoIP. Our numbers don't get rejected by WhatsApp Business, Telegram bot at scale, banking apps, or dating platforms.
  • Built-in MCP server for AI agents. Claude, Cursor, ChatGPT, and any Model Context Protocol-compatible AI agent can handle phone verification autonomously. We're the only SMS verification API that ships with an MCP server out of the box.
  • x402 stablecoin payments. Auto-topup from any crypto wallet โ€” Base, Polygon, Arbitrum, Optimism. No KYC friction for international developers.
  • Free public price endpoint. Query pricing for any service/country combo without an API key โ€” verify the API works before signing up.

Core capabilities

  • 145+ countries and 2,500+ services (WhatsApp, Telegram, Discord, Gmail, Snapchat, Tinder, banking apps, e-commerce, gig platforms)
  • REST API with OpenAPI 3.1 spec, webhooks, WebSocket for real-time SMS delivery
  • Drop-in sms-activate-style compatibility at /stubs/handler_api.php โ€” migrate by changing only the base URL
  • Pay-per-use from $0.05/code, no contracts, no minimum deposit, auto-refund on failed delivery
  • CORS enabled for browser-based AI agents and dev playgrounds
  • PHP SDK via composer require virtualsms/sdk; npm via npx -y virtualsms-mcp

Microsoft Security Essentials features and specs

  • Free
    Microsoft Security Essentials is completely free to download and use. This can be a significant advantage for cost-conscious users and small businesses who need antivirus protection without added expense.
  • Integration
    It is well-integrated with Windows, providing seamless updates and compatibility with the operating system, reducing the risk of system conflicts.
  • User-Friendly Interface
    The software features a simple and intuitive interface, making it easy for users of all technical levels to navigate and use.

    It offers real-time protection against a variety of threats including viruses, spyware, and other malicious software.

Possible disadvantages of Microsoft Security Essentials

  • Limited Features
    Compared to other paid and even some free antivirus solutions, Microsoft Security Essentials offers fewer advanced features such as firewall management, password managers, and more extensive scanning options.
  • Moderate Detection Rates
    While Microsoft Security Essentials provides adequate protection for most users, it may not have as high detection rates for new and emerging threats compared to leading antivirus software.
  • End of Support
    Support for Microsoft Security Essentials ended, which means the software no longer receives updates or official support from Microsoft. This leads to vulnerabilities as new threats emerge.
  • Lack of Multi-Device Support
    Microsoft Security Essentials is designed to work only on Windows PCs, thus lacking support for other operating systems like macOS or Linux.
  • Basic Malware Removal
    While it can remove common malware, it might not be as effective at dealing with more complex infections or rootkits compared to more advanced antivirus software.

Questions & Answers

As answered by people managing VirtualSMS.io and Microsoft Security Essentials.

What makes your product unique?

VirtualSMS.io's answer

VirtualSMS uses real SIM-backed phone numbers, not VoIP โ€” so it works with services that reject VoIP (WhatsApp Business, Telegram bot at scale, banking apps, dating platforms). It's also the only SMS verification API that ships with an MCP server for AI agents and x402 stablecoin payment support โ€” making it the first SMS API designed for both developers and autonomous AI agents.

Why should a person choose your product over its competitors?

VirtualSMS.io's answer

Three reasons:

  1. Real SIM numbers work where VoIP fails. Most competitors (5SIM, SMS-Activate, SMSPVA) lean heavily on VoIP. That gets blocked by services that matter โ€” WhatsApp Business, banking apps, dating platforms. Our numbers don't.

  2. Built-in MCP server for AI agents. Claude, Cursor, ChatGPT, and any MCP-compatible AI agent can handle phone verification autonomously through our MCP server. No other SMS API in this category ships with this.

  3. Pay-per-use, no contracts, no minimum deposit. From $0.05/code. Free API key. Public price endpoint lets you check pricing before signing up. Auto-refund on failed deliveries. x402 stablecoin payments for international developers who want to skip KYC.

How would you describe the primary audience of your product?

VirtualSMS.io's answer

Developers building OTP-dependent workflows: signup testing, QA automation, account verification at scale, and onboarding flows.

Growing segment: AI agent builders using MCP-compatible tools (Claude Code, Cursor, ChatGPT) that need autonomous phone verification capability.

Also: teams migrating from legacy SMS verification providers that no longer meet their needs โ€” either because their suppliers shut down or because their numbers are now blocked as VoIP.

What's the story behind your product?

VirtualSMS.io's answer

VirtualSMS launched because every SMS verification API on the market was either VoIP-only โ€” rejected by WhatsApp, banking apps, and most major services โ€” or built around legacy plain-text protocols that modern AI agents couldn't use natively.

We started with a modern REST API and real-SIM-backed numbers. We added an MCP server from day one, making us the first SMS verification service designed for both developers and autonomous AI agents. x402 stablecoin payment support followed โ€” removing KYC friction for international developers who'd been priced out of legacy providers.

Which are the primary technologies used for building your product?

VirtualSMS.io's answer

REST API over HTTPS with OpenAPI 3.1 specification

TypeScript MCP server (Model Context Protocol)

Mintlify-hosted developer documentation

x402 stablecoin payment protocol on Base / Polygon / Arbitrum / Optimism

WebSocket for real-time SMS delivery notifications

Webhook event notifications for async integration

sms-activate-style legacy compatibility endpoint (/stubs/handler_api.php) for drop-in migration

Who are some of the biggest customers of your product?

VirtualSMS.io's answer

-AI agent platforms integrating our MCP server for autonomous phone verification

-E-commerce QA automation teams testing signup and checkout flows

-Crypto-native developer projects using x402 stablecoin payments

-Developers migrating from sms-activate-style legacy providers
