Can someone please help me. I have i880 nextel cell phone. In my menu, under settings, there is a list. I click on DC OPTIONS. One of those options shows "Store recieved info" It talks about putting in a prefix. But does not go into detail how or what it is used for. I have called Nextel support more than several times, and no one knows what it is. Can some one explain to me in detail why do I need to put in a prefix , whats the purpose? What is it used for?
