Questions & Answers

As answered by people managing VirtualSMS.io and Memory.com.

What makes your product unique?

VirtualSMS.io's answer

VirtualSMS uses real SIM-backed phone numbers, not VoIP — 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 — 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 — 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 — 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 — rejected by WhatsApp, banking apps, and most major services — 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 — 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
