£5 SIM Only Deals

Not always. Spusu, Mozillion, Lycamobile, EcoTalk, and Asda Mobile all offer no credit check options in the current listings. The one exception worth flagging is Sky Mobile's £1.00 deal, the cheapest on the page, which does run a credit check. 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.

Spusu at £2.90 a month is still the pick for a no-strings deal: 1GB of data, 500 minutes, 500 texts, 5G, free EU roaming, no annual price rises, and no credit check, all on a 30-day rolling contract on EE. No annual price rises is the key point here, your £2.90 stays £2.90, which is rare even at this end of the market.

The cheapest deal on the page is now Sky Mobile at £1.00 a month: 1GB, unlimited minutes and texts, and 5G on O2. The trade-offs are that it's a 12 month contract rather than rolling, and unlike the picks above it isn't a no credit check deal. If the headline price is what matters most and you're happy to commit for a year, it's hard to beat.

If you want a touch more data on a rolling plan, Spusu's 3GB deal at £3.90 a month keeps the same 500 minutes, 500 texts, free EU roaming, and no price rises. Among the MVNO options, Mozillion has a 24 month deal at £3.00 a month with 1GB, unlimited minutes and texts, 5G, and EU roaming on EE, with the same plan on a 12 month contract at £3.50 a month if you'd rather not commit for two years.

If data matters more than commitment length, Lycamobile at £4.00 a month on a 24 month contract gives you 5GB, 1000 minutes, 1000 texts, and 100 international minutes on EE. It's worth reading up on mid-contract price rises before committing to any 12 or 24 month deal, as policies vary by network.

Yes, though not every network supports them. Spusu, Mozillion, Lycamobile, and Asda Mobile all have eSIM-compatible deals under £5 available. Use the eSIM filter above to narrow things down, or compare the full range on our eSIM deals page. If you're 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. The Spusu, Mozillion, and Lycamobile deals on the page all 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 gives you maximum flexibility with no long-term commitment, and Spusu's no annual price rises mean you don't sacrifice a fixed price to get that flexibility. The lowest monthly cost in the listings is Sky Mobile's £1.00 deal on a 12 month contract, while Mozillion's £3.00 deal ties you in for 24 months for unlimited minutes and texts. 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're confident in the network, a longer contract saves the most. 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.
