The deal is available through online retailer e2save on the Vodafone network.
You’ll get unlimited minutes and texts, and so much data you’ll struggle to run out.
The monthly cost is Â£33 a month, and the upfront fee is Â£55.
That brings the total price of the 24-month contract to just Â£847, which is very low given the phone and data on offer.
Normally, buying an iPhone 11 outright would cost you Â£729.
But you’d also need to fork out for a SIM every month too, which significantly adds to the cost.
That means you’ll save hundreds of pounds with this deal.
For instance, Vodafone’s closest SIM-only offer is an unlimited-data plan, which costs Â£30 a month.
That’ll come to Â£720 over two years, and Â£1,449 once you add in the price of the iPhone 11.
So the e2save deal is actually saving you Â£602.
The cheapest alternative offer from Vodafone that nearly matches the data is a 20GB plan.
It costs Â£20 a month, although you’ll get 40GB less data to use compared to the e2save deal.
The total cost (including an iPhone 11) over two years is Â£1,209.
That means you’re getting a hefty Â£362 saving with the e2save offer.
We reviewed the iPhone 11 back in September and noted how much better the handset is compared to the iPhone XR.
We said: “The camera is substantially better, offering loads more versatility and the mind-blowing Night Mode to boot.
“The iPhone 11 looks better, is physically more durable, and comes in a tempting suite of pastel colours.”
