Black Friday SIM only deals

It depends on the network. Budget MVNOs including Spusu, Lycamobile, Mozillion, Lebara, and Asda Mobile typically offer no credit check options. The larger networks including O2, Three, and Vodafone generally require one. If credit history is a concern, use the no credit check filter above, or browse our no credit check SIM only deals page for a broader view.

It depends on which type of network you are looking at. The budget MVNO market is competitive enough year-round that deals from networks like Spusu, Lycamobile, and Mozillion are often as good in April as they are in November. Where Black Friday tends to make more of a difference is at the premium end, with networks like O2, Three, and Vodafone occasionally offering meaningfully larger data allowances or lower prices for a limited period. If you are primarily looking at those networks, it is worth waiting until November. If you are already looking at budget MVNOs, the standard market listings are worth comparing now without waiting. Our network coverage guide is a good place to start if you are undecided on which network suits your area.

Black Friday deals often come with introductory pricing that reverts to a higher standard rate after one, three, or six months. Always check the full contract terms before signing up, and factor in the ongoing cost rather than just the headline offer price. Our guide to mid-contract price rises is worth reading before committing to any 12 or 24-month deal, as policies vary by network.

Yes, though not every network supports them. Spusu, Lycamobile, Mozillion, and Asda Mobile all have eSIM-compatible deals available. Use the eSIM filter above to narrow things down, or compare the full range on our eSIM deals page. If you are not sure whether your phone supports eSIM, our guide to what an eSIM is and which UK networks support them is a good starting point.

Yes. Most deals from the major networks and budget MVNOs now include 5G as standard. Whether you can access it depends on your handset and where you live. EE and Vodafone have strong 5G coverage in most major UK cities, while Three's footprint is still growing in some rural areas. Our network coverage guide is worth checking before committing to any network.

By default, deals are sorted by lowest monthly price. You can change the sort order at any time using the controls above the listings and filter by data allowance, contract length, minutes, and eSIM availability. All deals shown are updated automatically. SIM Only Finder is an Ofcom-accredited UK mobile comparison site and earns a commission on deals taken out via our links. This does not affect how deals are ranked.
