Not really a specific forum for this this question, but this one seemed the most likely to get a decent response.

I bought a GPS tracking unit in 2002 from a company called Asset Assured, unfortunately they went bust within the year and so I now have the unit and aerial but with no service.

Any (sensible) suggestions on what I can do with it?

Can it be used again as a tracker on another 'network'?

Cheers, Christian.
