Crypton.sh SMS Verification review: €1.50 one-shot codes that just work
If you only need a single SMS code to finish a signup, you don't want to rent a number for a month. Crypton.sh's SMS Verification service is the answer: a one-shot, flat-rate €1.50 verification number that lives for 30 minutes, supports 70+ services, and doesn't require an account or email.
Our rating
4.5 / 5
Editorial + aggregated user feedback
Verdict: A no-friction alternative to SMS-Activate and GetSMSCode, with the bonus that you can pay in Monero and don't have to top up a balance up front.
How SMS Verification works
The flow is intentionally short. You pick the service you want to verify against from a drop-down (Google, Telegram, Discord, Tinder, WhatsApp, etc.). Crypton.sh assigns you a one-shot number from a compatible range. You pay €1.50 in crypto or by card. The number is yours for a 30-minute session; you paste it into the target service, the verification SMS arrives in the Crypton.sh dashboard, and you copy the code back out.
That's it. There's no balance to top up, no monthly minimum, no captcha treadmill, and no email. If the verification fails for any reason — for example, the target service rejects the range — Crypton.sh refunds the credit so you can try again.
Supported services
Crypton.sh currently supports 70+ services, including the most commonly requested:
- Telegram, Signal, WhatsApp
- Google, Apple, Microsoft, Yahoo
- Discord, X (Twitter), Facebook, Instagram, TikTok, Snapchat, LinkedIn, Reddit
- Tinder, Bumble, Hinge
- Binance, Coinbase, Kraken (where SMS 2FA is still permitted)
- Uber, Lyft, Bolt, DoorDash
- OpenAI/ChatGPT, Anthropic/Claude, Perplexity
If a service isn't listed, the team adds it on request. Several reviews from 2025–2026 mention feature requests being implemented within a week.
Pricing
| Item | Price | Notes |
|---|---|---|
| One-shot verification | €1.50 | Flat rate, includes the 30-minute number |
| Failed verification | €0 (refund) | Credit returned automatically |
| Renew number for extra time | N/A | One-shot only — buy a Secure SMS rental for ongoing use |
Pricing applies regardless of country in most cases. Some specialist ranges may carry a small premium.
Pros and cons
What we like
- Flat €1.50 — no balance to pre-load, no surprise pricing.
- 70+ services supported, with new ones added on request.
- Refund credit if the verification fails.
- Buy without an account, pay in crypto.
- 30-minute session is generous compared with competitors' 10–15 minutes.
What could be better
- One-shot only — the number disappears after the session.
- Some services (a small minority) block all SMS-verification ranges; if yours is on that list, the refund still applies but you'll need a rented number or Crypton Mobile.
- No bulk discount — at scale, a rented number is cheaper than many one-shot verifications.
What users say
Aggregated from Trustpilot and KYCnot.me.
"Numbers are working everywhere. And this alone is quite rare. I have tried other services but the numbers were seen as reused by ex. Google."
