I recently bought the LG enV Octane & when I send a message to another Verizon WIreless sender, it will not show a Message Delivered icon. I have called Customer Services & they have said there may be a button to press; but i've done research & I am unable to find a key or button to press to show that icon. I know the icon insists, because it is in my icon glossary under my tools&settings menu. Please comment any helpful information. Thank-you.
