Hi, How phone to know the application type? So SMSC should transfer some smpp headers to phone and the header value is written by Kannel. Now I think the header is "service_type" and its value is "WAP". But kannel sets this value as NULL.
According to what you mean, phone will know the message is binary message and know the message is WDP PDU if received message is binary.
