Hey, I'm currently with O2 Pay and Go, on their Text and Web package that gives me unlimited web and text for £15 a month. However, I'm thinking of leaving O2 due to their rubbish 3G coverage, as well as their ****** customer support - someone stole my debit card details to top up their phone and O2 are refusing to give me any information required by my bank to investigate. Anyway, I was thinking of going on Vodafones Sim Only package, which offers 600 mins, unlimited text, and 500mb of web all for £20 a month. Not the best deal but will do. Does anyone have any experience with Vodafone Sim Only on their iPhone, and if their are any missing features. I already miss out on visual voicemail, and internet tethering anyway as I'm on PayG. Cheers!
