Icon meaning

[IBMJunkman]

Verizon S5 running 6.0.1

I use Message+ On one entry in the Conversations list there is a grey triangle with an exclamation mark in it. It is the conversation I have with my bank.

What does it mean?

Hi! Do you mean Messages + SMS app? If so, it might be an undelivered message(not sent). Does the icon appear next to a message you wrote? or is it a message you have received?

The icon is on the number entry in the Conversations list. I open the message list and found a message from June that was not sent. It had the icon also. I deleted all except the last 2 messages. Icon is gone.
Thanks.

Another question. What setting prevents me from sending a message if wifi is not turned on?
