I recently had to visit O2 as my phone wasn't connecting via a 3G network and was told I was on the wrong settings, as I have a simplicity tariff not an iphone tariff. My phone updated the operating system this morning and the same error is now occuring. I have checked the data settings and they are idata.o2.co.uk for cellular, mms and visual voicemail. Are these correct please? If so, why can't I now access the internet again? Thank you.
