Been with Vodafone since 2011. Phoned up and had to haggle a bit for this as the first guy was playing hardball and trying to charge me more than I have been paying insisting a 40% discount was the best he could do. Phoned back after some more research. Ended up being given the 1000 minutes / unlimited texts / 1GB plan for reduced price of £9.90 with an extra 5GB data per month for free. Happy!
