Three remains the only major UK network to offer unlimited “All You Can Eat” data for iPhone. For a high-end model like the iPhone 6s Plus with Three’s AYCE data, you can expect to pay £99 upfront and £64 per month. (You can also pay £149 for a slightly reduced monthly charge.) Right now the carrier is running a promotion that cuts your monthly bill to £30.50 per month for the first six months.
The 24-month plan also includes unlimited calls and texts.
