red triangle and exclamation mark, what dies it mean in text messages

[AC Question]

What does it mean when text messages have a red triangle and exclamation mark

 

[B. Diddy]

Welcome to Android Central! Is it a message you're trying to send, or one you received? If it's one you're trying to send, it probably means it couldn't be sent.

I just got two of those, as well, when I turned my phone back on. I've turned it off and on a couple of times since but they won't go away. Everything appears to have sent. Thanks!
