 Beeper says this new app has reversed engineered how iMessage works. Can do group chats, high res images, high res video, voice messages, stickers, gifts, reply threads. Beeper figured out how to craft an SMS message to register your phone with Apple Surgeon. The server then registers your phone number as iMessage capable. There's a lot of questions you may have like, is that secure? Well, it's tight. It's from your phone number. So it can only work with your phone number. You don't log in on that cloud server. You log in on the app on your phone with the Beeper login, not an Apple ID, and then you get a credential from Apple that says, oh, you're the you're the person I'm going to send these messages to. Here's the credential to get the notification. All it can do with that credential is ask the Apple server to send it a notification that a message has come in. It cannot use that credential to get your actual message. That credential to get your actual message stays on your phone.
