You can't send an unbind request if you do not have a currently open connection.

If the SMSC is returning this error, but your end of the connection is no longer valid, there is no way to tell the SMSC to unbind the connection that it thinks is still active.

Under normal circumstances, NowSMS sends an unbind before it disconnects from an SMSC. If the connection is lost because of network reasons, then you have to wait for the SMSC to detect that you have been disconnected. NowSMS will automatically retry until the connection can be made again.

thanks bryce,
first excuse me for my bad english

when i have this problem i phone to the person who manage the SMSC and he reinisialize my state but it is not an effective solution.
i am trying to program a small application which perform a socket connection to the SMSC through which i send an unbind command to réinisialize my state, i don't know if it is possible to do this??

"You can't send an unbind request if you do not have a currently open connection"

i programmed a small aplication to make a Socket connection to the SMSC it looks work correctly.( i don't know if this what you called a currently open connection")
what i need is the data which i must send to the SMSC in order to unbind from them (a string, int,..??? and the centent of this data)

thank you bryce
