I've been looking all over the forums and internet for an answer to this (maybe in all the wrong places). I know SMS sending doesn't work in Yosemite currently, but SMS also isn't working between my iPhone and iPad on iOS 8 beta 4. I have them both logged in with the same Apple ID and they are both on the same Wifi network. SMS messages sent from my iPhone show up on my iPad, but when I try to send them using my iPad they don't go through. Phone calls from my iPad work perfectly. There's no mention of SMS not working in the iOS 8 beta 4 changelog. Is there a setting I'm neglecting here? Just want to make sure I'm covering all my bases before I chalk it up to general bugitude.
