Deal allowance

Most contracts now offer unlimited texts and minutes. How much data you need depends on how you use your handset.

1GB per month: email, occasional web browsing and watching the odd YouTube video.

2GB per month: heavier web use, email regularly and occasional music and video streaming. For the average smartphone user, 2GB of usage should be just right.

3GB: Cloud-based photo services, streaming video, downloading music and regular email and social networks.

5GB or more: Regularly stream video and music, upload images to social networking sites and multi-player online games. Higher allowances let you make the most of your phone.

Contract length

One-month SIM only contracts give you the freedom to switch provider with just 30 days' notice if a better deal appears, while still providing more generous usage allowances than pay as you go deals. One month-sim only deals usually work on a rolling contract basis.

12-month SIM only contracts provide more generous usage allowances than one-month SIM only deals. However, because you're committing to a longer term deal, you haven't got the same freedom to switch if a better deal becomes available.

4G deals

If you use the internet beyond occasional email and web surfing, you'll want 4G. It's faster than 3G, provides smoother online video and music streaming and lets you do more of whatever it is you like doing.

iPhone SIM only deals are a fantastic way of cutting your monthly outlay on calls, text messages and mobile internet.

That's only half of what makes them so appealing, though. People also love the flexibility that an iPhone SIM only plan offers.

If you go SIM only, you're free to leave your contract at any time with no penalty and can upgrade to the newest iPhone models as soon as they go on sale.

Why choose an iPhone SIM only offer?

Standard iPhone contract price points and tariffs factor in the cost of the handset as well as day to day use of the phone and this is reflected in their cost.

However, iPhone SIM only deals only include calls, text messages and web usage, making them considerably cheaper.

The one-year product cycle for new iPhones also means that many people want to upgrade every year to have the latest model.

The great thing about iPhone SIM only deals is consumers can do exactly that and don't have to worry about being locked into a lengthy two-year contract.

Who can sign up for an iPhone SIM only deal?

In order to take advantage of an iPhone SIM only deal, you’ll need to be out of contract with your provider and have an unlocked phone.

If your iPhone is tied to a particular provider, you can get it unlocked by calling your network or dropping into a branch of their retail network. A fee of around £20 is usually applies.
