The N73 is a Triband GSM/UMTS phone and it’s possible to navigate in internet using the Wap browser, which features the Mini Map function where a preview of the web page is shown, in order to facilitate reaching the exact page section without the need of loading the full page. It’s also possible to connect the phone to the PC and using it as a UMTS modem. The synchronization with PC and other devices are possible thanks to the USB cable or bluetooth connection.

The SO used on the phone is the Symbian S60, with the same menu and applications that Nokia users are used to by now: agenda,MMS, SMS, converter, calculator, image editing software, games and other applications that are possible to be downloaded from the internet.
