About SimSMS
SimSMS is a virtual phone number service for SMS verification and long-term number rental, built for one purpose: letting you verify an account without surrendering your identity. There is no KYC, no email address, no password and no ID — anywhere in the flow. An account is a single seed phrase, payment is cryptocurrency only, and we deliberately keep no personal data to lose, leak or hand over.
What we do
We provide two things: one-time virtual numbers that receive a single SMS verification code (released the moment you are done), and dedicated number rentals you keep for 7 to 90 days for ongoing access. Numbers cover 190+ countries and work with 1,000+ online platforms — WhatsApp, Telegram, Google, OpenAI, Binance, PayPal and far beyond. Delivery is instant, and if a code never arrives the cost is refunded to your balance automatically.
What we stand for
No identity, ever
No email, no phone, no ID, no name. Your account is a seed phrase you generate — nothing ties it to you.
Crypto only
Pay in 20+ cryptocurrencies — Bitcoin, Monero, Ethereum, USDT, USDC, Solana, Litecoin and more. No card, no bank.
Zero data retention
We store no personal information and read no SMS beyond the code you came for. See our Privacy Policy for the specifics.
Auto-refund
If a number fails to receive your SMS, the balance is returned automatically — you only pay for codes that arrive.
Comment ça marche
- Pick a country and the service you need a code for — browse all of them under Numbers and Services.
- Top up your balance in the cryptocurrency of your choice.
- Receive your number instantly and wait for the SMS code on screen.
- Done — the number is released, or kept if you chose a rental.
Built for developers and agents
Everything available on the website is also available programmatically through our REST API and an AI-agent interface (MCP and x402), so automated workflows can buy numbers and read codes without a browser or an API key handed over by email.
Part of a privacy-tooling network
SimSMS is operated alongside a small family of privacy-first services — including anonymous hosting and servers and no-KYC infrastructure — sharing the same principle: useful tools that never ask who you are.
