What are the parameters which differentiates a text SMS and binary SMS in SMPP?
I assume both the messages are encoded in submitSM object. If not please tell how SMPP binary messages are encoded into a SMS.
Check data_coding parameter.
Here are some values:
0 0 0 0 0 0 0 0 SMSC Default Alphabet
0 0 0 0 0 0 0 1 IA5 (CCITT T.50)/ASCII (ANSI X3.4)
