If you're keen to save some money on your phone bill, iPhone SIM only deals are a fantastic way of cutting the monthly cost associated with a pay monthly plan. And you still get the same calls, text messages and mobile data.

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?

Most iPhone SIM only deals will include calls, text messages and data, making them considerably cheaper pay monthly contracts that cover the cost of a handset.

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.

The one-year launch cycle for new iPhones also means that lots of people want to upgrade every year to have the latest model. And 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?

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.
