iPhone plans with unlimited data
Want a new iPhone? Reckon you’ll be using it a lot? You’ll probably need a contract with a big data allowance - and it doesn’t get much bigger than unlimited.
How to find an iPhone deal with unlimited data
Use the comparison table above, and we’ll do all the work for you.
Simply select the iPhone models you like the look of, choose how much storage you want, and pick a colour if you have a preference, and we’ll show you all the deals available.
Then, select how much data you want on your plan - it might be a good idea to click ‘unlimited data’, by the way - and sort the results by cost to see all the cheapest deals first. Some may even have nothing to pay upfront.
Which networks offer unlimited data iPhone deals?
The only network to offer plans that really do have unlimited data is Three. You can use as much as you like - the fair usage cap is a monstrously high 1000GB, which we assure you you’ll never reach - and you get unlimited texts too.
Giffgaff has a plan with ‘Always on’ data. The amount of data you can use and download is unlimited - but your download speeds are throttled pretty significantly in the daytime once you’ve used 6GB in a month.
What’s the cheapest unlimited data plan for iPhones?
Giffgaff’s ‘Always on’ plan is the cheapest unlimited data deal - but remember it’s not truly unlimited.
Three’s unlimited plans are surprisingly cheap, starting from about £40 a month (plus upfront costs) for older iPhone models.
An even cheaper option may be to get a plan with a high data limit - unlimited data isn’t always necessary for everyone, after all.
How much data do I need?
Unlimited data is… well, it’s a lot of data. Possibly too much, in fact. Depending how much you use your iPhone when you’re on the go, you may be able to save money by picking a plan that does have a data limit, so long as it’s high enough to cover your usage.
To find out how much you use, try a data tracking app. Some are available straight from your network - My EE or My Vodafone, for instance - which can tell you exactly how much you’ve been using from your current plan.
Alternatively, tons of data usage apps are available from the App Store or Google Play Store. Keep one installed for a few weeks and check it regularly to see what your monthly usage is like.
When you choose an iPhone plan, bear in mind that 1GB data will let you watch video for two hours (one hour if it’s HD); browse the web and social media for about 40 hours; or stream or download up to 150 songs. It’ll let you use the internet on your iPhone more than you think - and you may get by just fine with a limited allowance instead, even if you’re a heavy user.

Which iPhone should I choose?
Released in September 2016, this is the most stylish and powerful iPhone yet, rocking a sleek design and quad-core processors. It has the benefit of being the only water-resistant iPhone so far, so you can use it in the rain without worrying, though it doesn’t have a headphone jack. You won’t want this phone to leave your hands - an unlimited data deal might well be necessary.
Alternatively, splash out a little more to get the iPhone 7 Plus if you’d rather have something phablet-sized. This one has a larger 5.5-inch, Full HD display, and a better camera with dual lenses.
It may be a year older than the iPhone 7, but the 6s is still an excellent phone. It’s got a standard headphone port for a start, along with a 12MP camera, up to 128GB memory, and a premium-looking aluminium body.
Again, you can spring for the iPhone 6s Plus with a 5.5-inch screen for something a little extra.
The iPhone 6 is an even older generation, but it’s only a slight step down from the 6s. The design and display are almost identical, and you still get things like a fingerprint sensor so you can use Apple Pay. And because it’s older, it’s quite a bit cheaper - meaning you can get an unlimited data deal for a wonderfully low price.
There’s a larger iPhone 6 Plus option here too - with a bigger, higher resolution screen, and a far longer lasting battery.
This is the one to go for if you prefer a smaller handset - it’s got a 4-inch screen instead of the 4.7-inch one you get with most iPhones. Most of the iPhone SE’s innards, however, match those in the 6s, so it’s still a great piece of hardware. We’re talking an A9 chipset, up to 128GB storage, and a 12MP camera.
