About 18SIM

Last updated: October 21, 2026

18SIM is a virtual phone number service that lets you receive SMS verification codes online, without using your real phone number. Whether you're signing up for a new app, protecting your privacy, or managing multiple accounts, 18SIM gives you a fast, disposable number for the moment you need it.

Why 18SIM

• Privacy first: keep your real number private when signing up for services you don't fully trust.
• Instant activation: numbers are ready the moment you purchase them — no waiting, no physical SIM.
• Flexible payments: top up with card or crypto, in whichever way suits you.
• Automatic refunds: if a code doesn't arrive, you're covered — see our Refund Policy.

How It Works

1. Create a free account and verify your email.
2. Top up your wallet balance.
3. Choose a service and country on the home page, and purchase a number.
4. Use the number to sign up on the destination site or app.
5. Watch the code arrive on your Activation page, and complete your verification.

Our Commitment

We aim to run a straightforward, reliable service: transparent pricing, fast delivery, and support that actually responds. If something goes wrong, our goal is to make it right — see our Refund Policy and Contacts page.
