Best SIM Only Deals

Anyone who owns a phone and wants to pay less for their data, texts and minutes. They're also a great way to save money for a month or two while you're waiting for a new version of your favourite handset to be released.

This one is entirely up to you. Take a look at the different benefits offered by each network, and check the coverage in your area. There are different perks available across ID and Vodafone, so take a look at which rewards you prefer.

A rolling SIM only deal doesn't have a specific end date, and rolls monthly, eliminating any contractual commitment. You can cancel at any time by providing your network provider with a 30 days’ notice.

No - Sim only is as the name suggests, and doesn’t come with a handset. You’ll just receive a SIM card which you can then pair with an existing phone you already own, or you could purchase a brand new SIM-free phone.

Yes, you’ll just need to contact your current network and provide 30 days’ notice to cancel your current contract. If you’re still in contract, you may incur an early termination fee. If you’re happy with your existing provider you also have the option to upgrade to SIM only if you prefer.

Choose from a 30-day rolling contract, which will let you change your package from month to month - or get a 12-month deal and enjoy even more minutes and data for your money. SIM only deals give you greater freedom and control.

Yes. All pay monthly deals require a credit check, however you can be passed for a SIM only deal with a much lower credit score than you’d need for a handset contract (although a credit check outcome can never be guaranteed).

A data cap is a feature offered by a number of networks that allows you to set limits on the amount of data you use per month. Many mobile phones also come with a data capping option built in which you should be able to find in the settings options on your device if available.

If you have transferred all of the information saved on your SIM card that you want to keep, like contact numbers, messages or media such as photos, the best option is to cut your SIM card with scissors making sure to damage the metal chip. This makes the card unreadable.

Yes, as with handset contracts, you are able to use your SIM when travelling. This however may come with an additional charge, this will all depend on your particular SIM only plan and network provider. Please check with your network provider before use outside of the UK.

Different handsets can require different SIM card sizes, however all of the SIM cards available at Mobiles.co.uk are combination SIMs (sometimes called multi-SIMs). These SIMs are perforated plastic, and can be snapped down to the required size. More information available here.

When a SIM-only contract ends, it reverts to a rolling-monthly SIM until you either cancel or upgrade. If you’re happy with its price and data, you can choose to continue for as long as you like. If you fancy a change, you can upgrade with a handset contract or a different cheap SIM only.

If you have a SIM-only Mobiles deal with cashback attached, you’ll receive this in one of two ways. ‘Automatic Cashback’ is sent to you at the start of your contract, whereas ‘Cashback by redemption’ is claimed at key months. Learn more about claiming cashback here.
