Is the card SIM locked? If not, you can still use it. I have a
card that was from T-Mobile .de, the software refuses to work even on
T-Mobile in the US (it checks the carrier and apparently doesn't
recognize T-Mobile USA as someone it "knows". It's simple to get around
this, just don't use the software (which is crappy/buggy anyway, at
least the one I tried) and use modem style "AT" commands to
configure/connect.

If it's SIM locked, I'm sure you can unlock it, but I have no
info on doing this or I would provide it.
