Hi, every couple of months or so I "lose" several GB of data. It simply disappears--this is not used data--from my mobile! Does anyone know why this happens? I've spoken to a Virgin operator but with no success.
Last Monday night I had just over 10GB unused data, next morning I had 4.2GB (approximately). My phone requires permission before updating and I only update when on a public network to save my data. I am a 'small data user', downloading no films etc.
