I have a year on a T-mobile contract for t-mobile internet service, It will not work on my new computer with the new express card,  It does work beautiful  with the older pc slot card. It is around $60 a month and well worth it. (can use on laptop anywhere - in the car, anytime when a cell tower is available)  Is anyone interested in taking over my contract - it runs for another year. contact me at cstahlman@yahoo.com and I will make arrangments and give you the card and SIM.
