You should check in the documentation of your phone, or possibly with the provider/manufacturer, what kind of possibilities and interfaces it provides to communicate with your computer and how you need to go about using them. Some phones will allow for the transmission of data via Bluetooth or infrared interfaces. However, the most reliable way that exists with almost any modern phone is the direct connection to the computer via a data cable. After the connection has been established, you can use the software suite that is provided by the phone's manufacturer to communicate with the phone and transfer data.
