- Why does my Sender ID have extra letters in front of it?
- Why is my Brand name not displayed as I defined it?
- Why do my messages have the initials MD in front of the Sender ID?
Sender IDs in India may be prefixed with additional letters to identify who delivered it and through which gateway.
So if the Sender ID is received as VD-TESTSMS, this will mean the carrier delivering was Vodafone, and the region was Delhi.
