Yep, like MaryBeth said.

What service are you and your friend on?

Yeah that's completely possible. Not only is it possible, it's fairly common, especially if the person you're sending the text to has a prepaid phone that's run out of air time. However, even contract carriers have network issues from time to time that can cause text messages to vanish into "la-la land".

I recently sent a text to someone and on my droid it said it was sent. She said she never received it....is this possible?
