Hi Mukesh, You should ask on the csipsimple issue list. This mailing list is more about pjsip issues. Well, about your problem : 1- did you checked the option "I'm allowed on 3G" in settings > easy configuration? (this panel also show the first time you boot the app, and if you take care of reading what's on screen you should have seen this option already). If you do not activate this option, the application will obviously not try to use 3G mobile data network to do sip ;) 2 - are you sure that your mobile carrier allow you to do sip on their network? Many mobile provider do block sip protocol over their mobile network. To this, nothing can be done from the application (else than supporting sip+tls and allowing you to use a sip provider that encrypt things). And even with that you must ensure that your contract with your mobile provider allow you to legally do voip usage on their network. Here in France 2 out of 3 mobile carrier prevent voip usage on their mobile network both technically and legally.
