I mentioned to the Salesman at the Mobile Shop that being a long term mobile customer I just needed extra GB when I renewed & he said it would cost me an extra £1.00. I currently pay £6.00 per month. However I now find that other providers like Vodafone, Plusnet give u 3GB for £6.00 n Lebara £4.95. It pays to check. Being a pensioner & low user on the minutes & texts given, an extra GB wld be most helpful esp as when our car broke down on the motorway. I'm now tied to a further 12 months as I'd recently renewed, would definitely change to a new provider next time!
