## Review

Crypton is a phone-number service that has been running since 2017: long-term numbers for calls and SMS, short-term ones for a single verification, a travel eSIM, and e-mail aliases. No name, no email, no ID at signup — you get an account identifier and that's it.

**What you get.** The long-term numbers are the useful part: one number you can keep, renew and use across services, rather than a pool number that disappears after a code. The eSIM starts around €5 a month and gets cheaper the longer you keep the line. Newer additions include iMessage lines ("Blue Relay"), a bring-your-own-SIM mode for people who want to host their own SIMs, and an API.

**Paying.** Monero is accepted alongside Bitcoin and other coins, and there's an onion mirror. Cards and bank transfers are also offered, which are not private payments — pay in XMR if that matters.

**The operator is named.** Crypton is run by Rinzler Labs, a Scottish company with a registered number and an ICO data-protection registration, and it publishes a privacy policy that says what it stores and for how long. That's unusual in this category and it helps if something goes wrong, though it also means a legal entity exists behind the service.

**Keep in mind.** Number pools are still numbers: anything you tie to a rented number can be lost when you stop renewing, and short-term verification numbers go back into circulation. Keep long-lived accounts on a number you control and renew it.
