What does it mean if an imessage doesn't say delivered on iPhone?

Every time I text my date it either says "read" or "delivered", but this morning I texted him and I haven't heard from him and the iMessage doesn't say read or delivered?

He can turn that feature off, and if he did then you never know whether its read or not.

Means it didn't deliver. Try sending again

Try this 1. Go to settings 2. Click on messages 3. Make sure Send Imessage and Send as SMS Message is both turned on 4. Resend text message and now it should deliver with no problem

He either blocked you or his phone does not have internet.
