This is an era of smart phones but still some of us still use the not so smart phones which have the basic features that a mobile phones should have. Some people use the mobiles with minimal features because they don't want their lives to be controlled by technology. They have some kind of allergy towards technology.They don't like carrying a brick sized mobile smart phone in their pockets. They are comfortable with communicating and browsing on the PCs. Yet sometimes they feel that the it would be better if the cellphone can be connected to the PC

some people work on computer for hours and when someone calls or sms on the mobile frequently it can be very irritating and disturbing switching between the mobile and PC. In those situations you might have felt the need for smsing and calling from the PC.

In this connection type there are four ways to connect your mobile. USB, Bluetooth, IrDA and serial cable. You can choose to search all the available connection types. Once done click next. Wammu will search for the cellphone within few seconds. After the search is complete, Wammu will display your cellphone. Select cellphone and click OK and proceed further to complete testing.

Now click on the phone menu in the menu bar and select connect, In few seconds wammu will be connected to the cellphone and status message at the bottom right changes from disconnected to battery charge status and signal strength of the network.
