If I put my iphone on Do Not Disturb will my messages say delivered if someone were to text me

I have an iPhone. If I were to put my phone on Do Not disturb is it like having my phone OFF?!

For example, if someone were to text (IMessage) me will it say deliverd on their phone to me?!

And if they were to call would it go straight to voicemail?!

You'd still get the messages but you won't get any notifications for them. Same thing if you put it on "airplane mode"
