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.
VirtualSMS.io's answer
Three reasons:
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.
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.
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.
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.
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.

We used their DC proxies and Residential proxies. Resi proxies were having quite low success rate. We had to use resi solution from other proxy providers. Unblocker didn't work well either also it was way too expensive.

The best web scraping tools 2026 leaderboard hasn't changed; the gap has narrowed. Bright Data remains the safest bet for any team that wants to spend time on the data, not on the scraping.
