  • Wide Service Support
    The platform supports a broad range of popular online services and platforms for SMS verification, including social media, messaging apps, and various other websites that require phone verification.
  • Multiple Country Options
    SMSCode.gg offers virtual numbers from multiple countries, giving users flexibility to choose numbers from specific regions depending on the service requirements or their geographic needs.
  • Pay-Per-Use Pricing

  • Privacy Protection
    By using virtual numbers instead of personal phone numbers, users can protect their real phone number and personal privacy when signing up for online services or verifying accounts.

Possible disadvantages

  • Numbers May Be Recycled
    Virtual numbers on the platform may have been previously used by other customers, which can lead to issues where a number is already associated with an existing account on certain services, causing verification failures.
  • Reliability Concerns
    SMS delivery is not always guaranteed, and some messages may arrive late or not at all, which can be frustrating when trying to complete time-sensitive verifications.
  • Service Blocking
    Many popular platforms actively detect and block virtual and VoIP numbers, meaning numbers from SMSCode.gg may not work with all services, especially those with stricter anti-fraud measures.
  • Limited Transparency
    As a relatively niche service, there may be limited public reviews and transparency about the company's operations, refund policies, and customer support responsiveness, making it harder for new users to assess trustworthiness.
  • Potential Terms of Service Violations
    Using virtual SMS verification numbers may violate the terms of service of many platforms that require real phone numbers, potentially putting user accounts at risk of suspension or banning if detected.

Questions & Answers

As answered by people managing VirtualSMS.io and SMSCode.gg.

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.

SMSCode.gg's answer:

SMSCode combines the lowest pricing in the market (from $0.0044/activation) with coverage across 200+ countries and a developer-friendly REST API — all wrapped in a clean, minimal UI. No bloat, no subscription, pay only for what you use.

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.

SMSCode.gg's answer:

SMSCode offers better pricing, wider country coverage, and a cleaner API compared to most alternatives. With 100,000+ active users and instant OTP delivery, it's reliable for both individual use and bulk automation workflows.

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.

SMSCode.gg's answer:

Developers integrating SMS verification via API, individuals protecting their privacy online, businesses and resellers running bulk SMS verification operations, and SMM panel operators.

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.

SMSCode.gg's answer:

SMSCode was built to solve a simple frustration — existing SMS verification services were slow, overpriced, and had terrible APIs. We built a clean, fast alternative from the ground up with a focus on reliability and developer experience.

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

SMSCode.gg's answer:

Rust (Axum), PostgreSQL, Redis, deployed on bare metal infrastructure for maximum performance and reliability.

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
