Many people forget that Vodafone do residential homes and broadband connections. I thought about changing, procrastinated, but then saw the savings. For me at home, it was over 20% reduction in spend. Now Vodafone have added even more value into some of the packages with the ability to add a Vodafone or national number to your account and talk free for up to an hour.
