Why WhatsApp, Telegram and banks block VoIP numbers, what a non-VoIP number really is, and when a real SIM number is worth it for verification and 2FA.

Crypton Mobile, BYOD, long-term numbers, and Blue Relay get cheaper every time you renew. The first charge is the price you see. It steps down from there, and it stops at a floor.

Crypton Chat and an OpenAI-compatible API are in beta. EU inference, default zero retention, encrypted history, billed from the Crypton credits you already have.

iMessage is where a lot of real conversations happen: friends, family, group chats, the client who will not open anything else. Green SMS is fine for codes. For talking to people, blue bubbles just feel better. Blue Relay is Crypton's way of giving you a dedicated iMessage number without buying another iPhone or linking it to your personal Apple ID. We host the phone in Europe. You get the line in your Crypton account, and you can use it from the dashboard or through the API if you want to automate things (including your own AI agents).

We're rolling out SIM return via InPost for long-term Crypton phone numbers, so when you're done with a dedicated-gateway rental, you can get the physical SIM card sent to a locker near you instead of losing it in the cloud.

A lot of you already recommend Crypton to friends, in forums, or on your own sites. We’ve wanted a proper way to say thank you for that — without turning the product into an ad platform. So we built an affiliate program. It’s pretty simple: you get a link, someone signs up through it, and if they actually use Crypton (buy an eSIM, rent a number, subscribe to something, etc.), you earn a small commission. That’s basically it.
