I experimented to send M-Notification.ind over SMS with Nokia 6610 connected to my computer.
I wrote a piece of code to set/combine user data header and user data, using Nokia_PC_Connectivity_SDK 3.0. But The recipient mms-enabled phone just recognised the message as an ordinary text sms message with strange characters.
The following() is how i set the sms user data header and basic sms parameters using nokia's connectivity SDK. (VB code)
