Just for knowledge sharing I found how to bring this icon to the handset :)
Usually the SMS when it's being sent from the network entity (SMSC) their is several data coding can be used based on your message lanuage as example for english latters data coding scheme 8 can be used as for Arabic or Russian text Unicode should be used so in order to display this icon all what is needed is to use new data coding scheme which is 0xC8, below is full descriptions about the usage of the DCS in the SMS headers.
The first nibble can be:
- (0xC) for Message Waiting Discard (do not store the text that is in this message)
- (0XD) for Message Waiting Store (do store the text that is in this message
The second nibble’s first bit represents on/off:
- (0×0) is set indication inactive
- (0×8) is set indication active
