sbc/at&t is the only phone service provider and after paying a hundred dollars a month for just their services, not including any long distance charges we've had enough. I got vonage because i wanted the whole package without having to pay an arm and a leg for it. Hehe, yeah we figured out that if the upload isn't fast enough it wasn't going to work. What the service tech at wildblue told us was that because we had the cheaper package we were getting enough upload so we bumped it up to the next one which is 59$ a month and he supposedly flipped a switch and let a little more juice come our way. UM NO! After testing it not only here but on www.speedtest.net i know for a fact that it is just barely above what dial up is. I am an online student and my husband is a nursing student so we need the internet. UGH what a mess.
