In Nokia SDK1.5 SMSC Emulator, if more than one application tries to login to SMSC with the same username then the login request is denied. My question is:

1. Is this the behaviour in real Nokia SMSC also?

2. If multiple logins for the same username are allowed and all the applications are listening for SMS from SMSC then how does SMSC forwards SMS's to all the applications? Does it broadcast SMS to all the listeners or it gives SMS to each one of them one by one.

Thanks in Advance.
