Audio Issue
After installation of 3g data card, audio option will be set as 'HSPAdatacard'. So we have to change audio option after installation to hear proper speaker audio.

1. Goto--> Control Panel
2. Select--> Sounds and Audio Devices
3. Select--> 'Audio' tab and select to your default audio device.
