I remember that tariff, they made sure to cut back on the data allowance when we upgraded to the iPhone 4.I'm currently with O2 on a Simplicity 20 for iPhone plan. It's a rolling contract which I've been on for what, maybe three years now?
Both Giffgaff and Three have unlimited data plans now between £12-15/month but the basic 4G plans are £26 for 1 GB on both O2 and EE, imagine how they could have ended up at the exact same price, some coincidence! Vodafone don't even offer a 1-month 4G SIM-only plan, it's 12 months minimum.
It's almost like the networks have cosied up together and agreed not to compete on price. And then in complete contrast Three say they won't charge any more at all for 4G. I hope they have the backbone capacity to handle 4G as I can see a lot of people switching to Three.
