You should get an iPhone if you want an iMessage chatting experience and are on Android. That’s what I and many others have told you, especially since the Beeper Mini saga started. That’s the only way to get iMessage. Expecting any workarounds from Beeper is akin to stealing access to Apple’s chat service.
It turns out that Beeper is now advising you to somehow get a Mac or iPhone to have iMessage working on your Android device. It’s beyond silly at this point.
