Smart phones use GPRS to connect to your mobile carrier and allow you to roam. GPRS is the wireless network that allows calls to be made and voice mail messages to be received, and it carries your voice over the airwaves. There are times when you may need to open (turn on) your GPRS if it becomes closed (or turned off). When your GPRS is open, you can select a network to connect to.
