Why aren't my sent messages from iPad and iPhone syncing? I sent someone a message from my iPad through iMessage and I know that my devices always syncronise my iMessage stuff, so it should have popped up on my iPhone that I sent the message (as both were beside me). However, it didn't pop up on my iPhone - there's no evidence of me ever sending the message - but it's still on as Delivered on my iPad. 

Has the message been received or was it glitched and never got to the recipient?
When you send a message from iPhone Messages app, all your messages are texts, but not all your texts are SMS.
