[Hampshire] Mobile broadband on an Asus eeePC 701?

Hello folks

A friend of mine has an Asus eeePC 701 4G, running whatever version of
Linux it shipped with (version 'eeePC 1.0.6.6' apparently).

He has asked me about mobile broadband dongles -- he just wants to
connect occasionally, so he wants a pay-as-you-go arrangement.

I am ignorant of both eeePCs and mobile broadband, but I said I'd ask
around.

Can anyone make any recommendations?

cheers

chris
