Now three companies offer a new wireless service via your phone – all you need is a dongle.
From about £10 per month you could have a dongle that you plug in to your PC and get instant internet access – as simple as that. Naturally you’ll need to be in an area covered by a mobile phone network, preferably 3G.
This could be a solution to fieldwork, sports days, remote buildings, teachers away at meetings etc. Maybe a couple per school that could be booked out as needed.
