Good question. PagePlus is an MVNO (mobile virtual network operator). This means that PagePlus can resell Verizon service, program phones, provide customer service for people who get a prepaid phone with them. Verizon tends to be pickier than other carriers on allowing MVNO arrangements...while for instance you will see many MVNO's for AT&T/Cingular and other carriers, you can probably count the number of Verizon MVNO's on the fingers of one hand. Thinking CDMA Tracfones in some areas, PagePlus, Locus CDMA, Lucky Wireless, some American Wireless business resellers like CT Telephone; may be a few more. Someone from PagePlus can likely answer this more completely than I can.
