SIM-only deals can save you money on your phone bill every month. Compare the UK’s best value SIM-only deals.

In the UK, there are currently more than 20 different mobile networks offering SIM-only deals.

Switching to a SIM-only deal can be a good way to save money on your phone bill as you’ll get a low-cost SIM card with inclusive minutes, texts and mobile data. You can also keep your existing phone number when you switch to a SIM-only deal.

In this article, we’ll review and compare the UK’s best value SIM-only deals. This includes SIM-only deals from big name mobile networks such as EE, O2, Three and Vodafone. We’ll also look at lower-cost providers including giffgaff, iD Mobile, SMARTY and VOXI.

SIM Only Deals: By Type

There are a couple of different types of SIM-only deal, depending on the features you’re looking for. For instance, you might be looking for an unlimited data plan or a Pay As You Go SIM card.

    I know this is an old thread but does anyone know of any payg or 1 monthly providers that allow you to pay the bill early? Smarty lets me top up in a shop and they use that cash for the bill, any others that can do that? Thank you.

  • Melissa said:

    Hi Ken,

    Please help. Is there any sim contract in the world that does not include any data? I need a mobile phone set up with absolutely no possibility of internet access. So ideally would be a large old fashion sim (not micro sim) for an old style Nokia phone, with only calls and texts. Thanks.

    Hi Ken
    Some months back I purchased a brand new SIM free Samsung Galaxy A20e with a view to switching from my present Samsung Galaxy J3 model – (purchased from EE and presently use on a pay-as-u-go basis) – believing my J3 SIM card would fit the A20e model – wrong!
    So now I’m thinking of arranging a SIM only contract with another provider but wonder whether I have to purchase a mobile ‘phone from them before going forward?

      Hi there,
      Thanks for your comment. No, there’s no need to buy a mobile phone from the other provider. You can simply order a SIM-only deal (like one of those listed above) and that SIM card can slot inside your SIM-free Galaxy A20e.
      Hope this helps!
      Ken
