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).
