12 month SIM only deals

Not always. Lycamobile, Mozillion, and Asda Mobile all offer no credit check options at this contract length. iD Mobile does require one. If a poor 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.

Lycamobile at £4.50 a month is the cheapest starting point: 5GB of data, 1000 minutes, 1000 texts, 5G, no credit check, on EE. Mozillion also comes in at £4.50 a month with unlimited minutes and texts and EU roaming included, also on EE, though with just 1GB of data. If you need more data without spending much more, Asda Mobile has a 3GB deal at £5.00 a month on Vodafone with unlimited minutes and texts, free EU roaming, and no credit check. For heavier data users, iD Mobile on Three offers 15GB with unlimited minutes and texts for £6.00 a month, also with free EU roaming. Lycamobile has a 10GB option at the same £6.00 price point on EE, worth considering if EE's coverage strength matters in your area, though that deal includes a promotional first month at £3.00, with the standard £6.00 rate from month two. Before committing to any 12 month SIM only contract, it's worth understanding how mid-contract price rises work, as some networks reserve the right to increase your monthly cost during the term.

Yes, though not every network supports them. Lycamobile, Mozillion, Asda Mobile, and iD Mobile all have eSIM-compatible 12-month deals 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. Whether you can actually 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 a look if you want to compare before committing to a year.

A 12-month deal balances cost and flexibility better than the alternatives for most people. You'll typically pay a pound or two less per month than an equivalent 30-day plan, and you're only tied in for a year rather than two. A 24-month SIM only deal will usually save you a little more each month, but you're committing for longer. A 30-day SIM only deal gives you maximum flexibility with no long-term commitment, though you'll pay noticeably more per month for the same allowance.

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.
