I have an ATT Option GT Max 3.6 Express aircard for sale. $20 includes shipping and dongle wire for connecting to an external antenna. Works great in ATT coverage areas but I live and chase in areas which are not all that ATT friendly. Needs SIM card and data plan from ATT. If your ATT cell phone has a SIM card and you have a data plan, put the SIM in the aircard and it works like a charm.
