Hi, Sorry about that, I'm on my iPad now, so I can actually type in the message box.
Tried this morning on my 1020, but whilst I could type in the title box and put smileys in the main message box, the keyboard would pop up and immediately go down again if I tried to type a message. So I tried (and obviously failed) to fit my query into the title.
Anyway my original question was how do I turn off cellular data on a 1020. I've found instructions on the net, but they say for US phones. I don't seem to have the cellular option in settings. I have a sim free UK phone running on Three.
