VIRGIN Mobile has joined the other six UK operators offering Internet connectivity on the move.
Users have to sign up for 18 months to get 3GB access allowance for £15 a month. Virgin will throw in a free USB dongle.
This package amounts to around 2,000 emails or 100 hours of surfing – however if the customer goes over this amount they will end up paying another £15 for each gigabyte. µ
As great as that is, it doesn't appear they have any Pay As You Go offerings yet so to be honest I'd rather just go to T-Mobile instead.

I don't want to be stuck on an 18 month contract for something I'd only use every so often. Shame really as being a Virgin Mobile PAYG customer I would have got one of these if it was also on PAYG.

If anyone's on one of these capped ISP deals check out NetMeter 1.1.3 . freeware, See how slow/fast your connection is AND most importantly lets you set notifications for a total data limit per day/week/month. I've used it for years and it even works on bloody vista 64.....
This explains a lot better than I can...
