Everything you need to know about SIM only deals

SIM only deals on amazing networks

What are SIM only deals?

SIM only deals are similar to a standard mobile phone contract, except instead of getting a new handset with your purchase, you simply get the SIM card. You then pair the SIM with your own handset, and you’re ready to go.

By not having the cost of a handset to pay back through your monthly line rental, our cheap SIM only deals are generally more budget-friendly than mobile contracts. Big data users can enjoy large monthly allowances at lower monthly costs, alongside shorter contracts.

Why buy SIM only?

If you've come to the end of your contract, and you still like your handset, there's no obligation to upgrade to another one. If your phone is in good condition and you don't want to part with it, just pair it with one of our best SIM only deals and start saving.

If there's a new flagship handset on the horizon that you're waiting for, but your current contract has already ended, don't pay larger bills for the next few months. You can also discover great cashback incentives on selected deals to help you save even more.

SIM only upgrade deals


Who are SIM-only deals best for?

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.

Which network should I choose?

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.

What is a rolling SIM only deal and how does it work?

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.

Do I get a new phone with a SIM only deal?

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.

Can I switch from a phone contract to SIM only contract?

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.

How long does a SIM only contract last?

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.

Will there be a credit check on a SIM only deal?

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).

What is a data cap?

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.

What should I do with my old SIM card?

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.

Can I use a SIM only contract abroad?

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.

What size SIM do I need?

Different handsets can require different SIM card sizes, however all of the SIM cards available at 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.
