hey there, we used the connectivy kit with alltel and it worked great for rhe last two years, when we bought this new computer we went with bluetooth and altel sells a 80211g that sends and receives at around200-500kbps.if you are in a anilog area and /or the broodband won't work in a bad signal area there is a standard dial-up 14.4kbps that helps cover the dead zones. don't know if you have seen this or noy we have had this and so far its great. we have unlimited service,nationwide service,no roming and no long distance for $70. a month and no minites. 24/7. great when im using gps in the streets and trips!
