iPhone 6 Thought I'd pass on this bit of info which no doubt is already on the forums somewhere. I was recently charged over £4 for picture messages that I thought I didn't send. However it turns out that I had the " subject field" turned on in settings. So when I entered text into the subject field this became chargeable as a picture message. I did find it in the T&C's. I've now disabled the setting. Lesson learnt.
