Symbol on sent messages (sms)

[celine]

hi there!
I just recently bought my first smartphone and have a question:
There is always this symbol on my sent messages (sms) that looks like the symbol that says "problem with the delivery" (it's a little envelope with a green exclamation mark).
but my friends always get my messages. does anyone know what this symbol means?
I also have the problem that I don't get a delivery status notification even though I clicked "yes" for "always send a notification"...

can anyone help?
thanks!!

Lol, my original rwply was for another thread.

That little green symbol is "i" not "!". Press and hold the symbol to bring up a menu and choose view report.

If it has not been delivered then I don't get the i symbol. All pending messages generate a warning sign by the persons name in the all measages page
