£5 SIM Only Deals

Not always. Spusu, Lycamobile, Mozillion, Lebara, and Asda Mobile all offer no credit check options in the current listings. 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 across all contract lengths.

Mozillion at £3.00 a month is currently the cheapest deal on the page: 1GB of data, unlimited minutes and texts, 5G, EU roaming, no credit check, on a 24-month contract on EE. If you want a shorter commitment, the same Mozillion plan on a 12-month contract comes in at £3.50 a month. For 3GB rather than 1GB, Mozillion also has a 24-month deal at £4.00 a month with unlimited minutes and texts on EE.

If you want a 30-day rolling plan with no long-term commitment, Spusu at £3.90 a month is the strongest option: 3GB of data, 500 minutes, 500 texts, 5G, free EU roaming, no annual price rises, and no credit check on EE. For unlimited minutes and texts on a 30-day plan, Spusu's 5GB deal at £4.50 a month offers the same terms.

Lycamobile comes in at £4.00 a month on a 24-month contract with 5GB, 1000 minutes, 1000 texts, and no credit check on EE, which suits anyone who wants more data and is happy to commit for two years. Lebara's 30-day deal at £4.50 a month on Vodafone includes 5GB, 1000 minutes, free EU roaming, and 100 international minutes, and drops to £1.49 a month for the first three months with the code LEBARA5. It is worth reading up on mid-contract price rises before committing to any 12 or 24-month deal, as policies vary.

Watch out for promotional pricing

Lebara's introductory rate of £1.49 a month applies for the first three months only when using the code LEBARA5. The standard rate of £4.50 a month applies from month four. Always check the ongoing cost before signing up, not just the headline price.

Yes, though not every network supports them. Spusu, Lycamobile, Mozillion, and Asda Mobile all have eSIM-compatible deals under £5 available in the current listings. 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. All of the deals currently listed include 5G at no extra cost. Whether you can access it depends on your handset and your location. EE and Vodafone have strong 5G coverage in most major UK cities. Our network coverage guide is worth checking before committing to any network.

At the £5 and under price point, all three contract lengths are available. A 30-day rolling plan from Spusu or Lebara gives you maximum flexibility with no long-term commitment, though you give up the ability to lock in a price for longer. Lycamobile's 24-month deal at £4.00 a month is the cheapest overall monthly cost in the listings, but ties you in for two years. A 12 month SIM only deal sits in between, giving you a fixed price for a year without the longer commitment. If your circumstances are stable and you are confident in the network, the 24-month route saves the most money. If you value flexibility or are unsure about coverage, rolling 30-day is the safer choice.

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.
