A. One option is the Socket Communications Digital Phone Card. The company supplies all the major adapters you need to make this type of connection work. If you have a Compaq iPAQ with a PC Card sleeve or an Amigo PD-600C (that has a built-in slot), you can use a Sierra Wireless AirCard 300 with the Verizon Wireless Service to share the minutes you have allocated to your current Verizon CDMA voice service. Check with your local wireless provider to see what your provider offers.
