I used your class to send messages and it was perfect. But when the ip and login credential has changed, there exists binding problem. no problem connecting the ip but the smpp server side says that it can be because of the system id and password includes characters like @. before only they were numerics and characters.
do you have any opinion about the problem?
also for charging i will use this connection. how can i use tlv parameters?
