Fantastic - but not quite 5-star
Brilliant idea - no frills airtime provider that's so cheap it's worth buying your own phone. Massively undercuts Vodafone, O2, etc. But they leave too much for customers to find out for themsleves. You need to be a tiny bit techie - and that wouldn't be necessary if they had better instructions available via a comprehensive menu and search facility on the front page of their website. SAs it is even a basic thing like getting your data settings right can be a nightmare.
