I have a "Data Connect" "Mobile Office Kit" from Cingular, which has a
USB cable and a CDRom with QuickLink software, and a Motorola T720.
The day I bought them, all worked. Not since. Wireless Internet (pay
by the minute) works, but Wireless Internet Express (pay by the
kilobyte) gives "PPP link terminated". Cingular tech support said at
one point that I needed two software capabilities at their end and my
plan only paid for one. Then they said they would make the one be
Internet Express. Still no luck. Does anyone have this working, and if
so, how did you manage?
