iPad iMessages vs iPhone iMessages
I'm able to send an iMsg from my iPad to one of my contact's iPhone (phone no.) as a regular BLUE iMsg -- Cool & Good. But when I try try to do the same on my iPhone, i.e. send an iMsg from my iPhone to the exact same contact (an iphone number), the iMsg on my iPhone only display as a GREEN msg -- why isn't it BLUE? The iPad recognizes the contact's iPhone number as being "on" (iMsg), but why is the iPhone to iPhone to msg GREEN? The contact's iPhone iMsg must be on -- right? Since the iPad can reach it with a BLUE iMsg....Your assistance would be greatly appreciated. Thank You.
iPad Air, iOS 8.3
