A couple of weeks ago I went to America so I turned off my mobile data so I didnt pick up a large bill. Since returning to the UK I've switched my data off but it won't let me use it. It's not connecting me to the Internet on my phone or letting me use any of my apps when I don't have wifi. I've turned phone off and on so many times looked at settings and nothing is happening. Can anyone help as this is so frustrating thanks?
