I have a question about texting on my S6

[AC Question]

sometimes after is send a text on my S6, it says sent...but when i look at it later there is a triangle with an ! exclamation point in it next to that text message, does this mean the text actually didn't go through?

It appears that the text message didn't send. When you say "sent", do you really mean it says "sending"?
