I have an iPhone 4 on monthly cpntract with Vodafone. As the title says, I can use the internet with no problem at all whenever I am in a wifi zone, including at home, in Tesco, anywhere with free wifi where I have a valid password. However, I can't get the internet, send/receive email. use Whats App when I'm outside these areas. I've read through the forum and I think my settings are correct. If anybody could post exactly what the settings should be or suggest anything else, I'd be grateful.
I can send and receive phone calls and mms.
I haven't got Airplane mode on
My account says I 've used 40mb of data so it must have worked at some stage.
All my settings were correct. I could sit next to people with a Vodafone iPhone 4 and they could get data and I couldn't. I solved the problem by the hugely scientific act of uninstalling Facebook and then re-installing it. Everything works fine now. I have no idea if the Facebook thing had any effect, but whatever happened it all works.
