Crypton.sh, operated by Scotland-registered Rinzler Labs, is a phone number service paid primarily in crypto (Monero, Bitcoin and other coins, next to cards and bank transfer). Its offer spans five plans: one-off SMS Verification numbers, Short-term Phone Numbers on physical SIMs, Long-term Phone Numbers on dedicated physical lines, cloud-based Virtual Numbers, and Crypton Line eSIMs.
- SMS Verification: one-time numbers for account signups, from unknown per code, with a unknown-minute session per code. Each session permits one incoming message; the numbers are receive-only.
- Short-term Phone Numbers: physical SIM cards rented for 1–6 months at country-specific monthly rates (currently listed for Germany and Poland); the entry price rose when the cheaper UK option was dropped at the end of October 2026.
- Long-term Phone Numbers: prepaid bundles on dedicated physical lines; pricing is only shown on the purchase page, no monthly rate is published.
- Virtual Numbers: instantly activated cloud numbers for SMS in and out, from unknown per month — the cheapest monthly rental rate Crypton publishes.
- Crypton Line: a real number on an eSIM for selected countries.
According to its terms and conditions, Crypton.sh states it will never willingly ask users to undergo a KYC procedure. Support runs through encrypted tickets in the account and SimpleX Chat.

How the score is made up
6.5 of 10 · average
Weighted sum of the criteria, each 0 to 10 from proven values. A criterion without data is not scored and counts with the category median, not as 0.
Capped at 6.5: trust is low (young brand, little disclosure or incidents).
The score uses the entry variant SMS Verification; sorting stays with it. With another variant: Short-term Phone Numbers 6.2
