Are these real SIM cards or VoIP numbers?

Real physical SIM cards from licensed mobile operators in EU, US, UK, Asian and LatAm countries. VoIP numbers from providers like Twilio and Google Voice are routinely blocked by WhatsApp, Telegram, Tinder, and most major services — VirtualSMS numbers pass those checks because they originate on real cellular networks.

How fast is delivery?

Most SMS arrive within 30-60 seconds of the service sending the verification code. If the SMS does not arrive within 20 minutes the activation is auto-refunded to your VirtualSMS balance — no dispute, no support ticket.

What payment methods are accepted?

Crypto via NOWPayments — USDT (TRC-20, ERC-20), BTC, ETH, LTC, BNB and more. No KYC, no phone number required from you. Card payments are intentionally not offered for privacy reasons.

How many countries and services are supported?

145+ countries with live SIM inventory and 2500+ services with per-country pricing. The supported list is published on the services page and country index, both kept in sync with live inventory.

Do I need an account?

No account is needed to view free shared numbers at /free-numbers. For dedicated private numbers — required for WhatsApp, Telegram, and any service that flags shared numbers — create a free account, top up with crypto, and start renting.

Is there an API for developers and AI agents?

Yes. Full REST API at /docs covering rent, activate, poll, cancel, and refund. AI agents can use the VirtualSMS MCP Server for one-install integration with Claude, Cursor, Codex, Windsurf, and other MCP-compatible clients.
