United Kingdom · SIM-only
Compare UK SIM-only deals with a starting price below £10 a month. Some offers rise above £10 after an introductory period, so check later payments and total contract costs before choosing. Filter the live deals by data, contract and network.
No current offers match these filters.
Filter by Price, Data, Contract or Network, and use More options for 5G, eSIM and EU roaming. Hard £10 limit? Check the regular price after any promotion, any disclosed rises and the minimum commitment before comparing data allowances. These filters do not guarantee that later bills stay below £10. Read Full plan details, then use View Deal to check the provider's final terms.
Not necessarily. A plan can appear here because its introductory monthly price is under £10, even when the charge rises later. If you cannot afford £10 or more in any month, the opening price alone does not tell you whether a plan fits your budget.
| Price test | What it really tells you | Safe for a strict sub-£10 monthly cap? |
|---|---|---|
| Starting price | What the plan costs at the beginning, potentially only for a promotion | No. Check the later payments. |
| Ongoing price | The regular charge after any introductory offer | Only if it remains below £10 throughout the period you need, allowing for any disclosed increases. |
| Effective monthly cost | The displayed total divided across the period used in the calculation | Not necessarily. An average below £10 can still include individual bills of £10 or more. |
| Minimum contract cost | The displayed total for the minimum commitment | Useful for affordability, but check what it includes and whether any extra or scheduled charges are excluded. |
Strictly speaking, £10.00 is not under £10. It may be a reasonable alternative, but it does not meet a ceiling of less than £10. Some guides use “under £10” informally to mean “£10 or less”; if your limit is exact, compare the pounds and pence rather than the label.
For a firm monthly ceiling, compare the highest known payment during the time you need the SIM with your budget, including scheduled changes. A cheap first bill or low average is not enough. If a future increase is permitted but its exact amount is not reflected in the displayed total, treat the plan's full cost as unresolved until the provider explains it.
Consider two illustrative plans, not live offers. Assume both run for 12 months, with no extra charges or additional price changes:
| Plan A: introductory offer | Plan B: steady price | |
|---|---|---|
| Monthly schedule | £5 for 3 months, then £12 for 9 | £9 for all 12 months |
| Total over 12 months | £123 | £108 |
| Average over 12 months | £10.25/month | £9/month |
| Highest monthly payment | £12 | £9 |
Plan A looks £4 cheaper on day one, yet costs £15 more over the year and breaches the £10 monthly cap once its promotion ends. The right comparison is the actual payment schedule and commitment, not just the card's largest data allowance or lowest displayed price.
For a 30-day rolling plan, a displayed “minimum term cost” may cover only the initial billing period: it is not automatically a 12-month estimate. Also check whether a bundle renews every 30 days or is billed by calendar month. For a 12- or 24-month contract, read the minimum contract cost alongside any separate permitted price increases, upfront charges and the cost of leaving early. Where the card shows an effective monthly figure, treat it as a comparison aid, not a promise that every bill will be that amount.
The best-value cheap SIM is the one that covers your routine without forcing paid extras or an unaffordable later bill. Use your biggest constraint to narrow the listings:
| Your non-negotiable | What to prioritise in the live deals | What should make you pause |
|---|---|---|
| Never pay £10 or more a month | Regular monthly charge and every scheduled increase | A short discount followed by £10+ payments, even if the average looks attractive |
| Leave easily if circumstances change | 30-day rolling or short minimum terms and cancellation rules | A larger data allowance tied to 12 or 24 months |
| Stay connected at home and work | A provider with suitable underlying network coverage | Extra gigabytes on a network that struggles indoors |
| Avoid paying for data top-ups | An allowance that comfortably covers your usual non-Wi-Fi use | A tiny bundle that repeatedly sends you over your allowance |
| Use an eSIM or travel abroad | Confirmed features on the exact plan | Assuming all cheap SIMs include eSIM or the same EU roaming allowance |
Check your phone's mobile-data settings or your current network account for the last few typical billing periods. Include months when you travelled, commuted more or used your phone as a hotspot: a single quiet month can make a small allowance look safer than it is.
If you use very little mobile data, start with 5GB SIM deals and compare the actual cost of any excess data. If you are regularly close to a limit, check 10GB SIM deals or 30GB SIM deals; these are data-focused comparison pages, not a guarantee that every result will meet the £10 ceiling.
Buying more data can be sensible when it prevents predictable top-up charges. Buying far more than you use just because the headline price is briefly low is not a saving. Ofcom likewise recommends checking real usage and comparing the full cost, including add-ons.
Coverage can decide between two otherwise similar offers. Use Ofcom's Map Your Mobile for your home, workplace and other important locations, then check the provider's own coverage information. Ofcom reports indoor and outdoor coverage and local performance estimates; buildings, trees and other conditions mean actual experience can differ.
The name on a cheap SIM is not always the name of the network providing its signal. Check the network shown on each live card, and verify any network sharing or access claims that matter to you. An advertised 5G allowance is of limited value if the signal is poor where you normally use the phone. Where home reception is weak, also check whether the particular provider and handset support Wi-Fi Calling.
A 30-day rolling SIM generally gives you more room to change plans if prices, needs or coverage change. That flexibility has value when your income varies or you expect to move. Read the notice and renewal terms: “rolling” does not by itself promise that the price can never change, and a 30-day bundle is not necessarily the same billing interval as one calendar month.
A 12- or 24-month SIM-only contract may offer more data for its advertised monthly price, but it can leave you paying after a promotion ends, or owing an early-exit charge if you want to leave before the minimum term. If your £10 cap is essential, a bigger allowance does not justify an unaffordable commitment. Use the Contract filter here, or explore 30-day and no-contract SIM deals to compare flexibility separately.
No. There are two different things to check:
An offer marked no annual price rises can still have a higher price after an introductory discount expires. It means something different from “the amount shown today is guaranteed forever”. If price stability is more important than maximum data, compare the dedicated SIM deals with no annual price rises and verify the individual terms.
The deal card helps you shortlist; the provider's order page is where the final decision should be made. Before accepting a contract, check:
If the provider's final terms disagree with the DealPriceCheck card, rely on the confirmed checkout terms before paying and do not proceed on the assumption that an older price will be honoured. DealPriceCheck compares selected providers, not every SIM available in the UK; the dataset's checked date is a timestamp, not a guarantee that an offer remains unchanged. See how DealPriceCheck compares offers.
Once you have found a plan that fits your budget, open Full plan details and then View Deal to continue to the provider. Before ordering, check whether your existing minimum term has ended. You can text INFO to 85075 to request contract and potential exit-charge information.
To keep your current UK mobile number, text PAC to 65075 from that number and give the code to the new provider. Ofcom says the PAC lasts 30 days and the new provider should normally complete the switch within one working day of receiving the code. Don't cancel the old service independently before arranging the number transfer. See Ofcom's switching instructions.
If even a small price increase would cause difficulty, do not buy on the assumption you will remember to leave when a discount expires. Choose a payment schedule you can sustain, and check the renewal date in your calendar. Eligible people receiving certain benefits may also want to check Ofcom's information on social tariffs, which can offer another route to an affordable mobile service.
Sometimes. Ofcom says traditional pay-as-you-go does not require a credit check, but a rolling SIM-only offer is not automatically exempt and a longer pay-monthly contract may require one. Check the provider's application rules for the exact tariff; “30-day” describes the commitment, not necessarily the credit-check policy.
No, not literally. £10 per month meets an at-or-below-£10 budget, not a below-£10 budget. Some other articles use the phrase loosely; here you should judge the exact amount shown in pounds and pence.
Yes, some qualifying offers can. Use the 5G or eSIM filters and confirm availability on the precise plan. You will also need compatible equipment and suitable coverage for 5G, and a supported handset for eSIM.
It depends on the plan. Some offers include roaming in specified European destinations, often with a smaller data allowance than the UK plan; others charge separately. Check the eligible countries, fair-use limits and charges rather than assuming a cheap domestic SIM will work abroad at no extra cost.
There is no universal winner for every postcode or user. Check local signal and the features you need first. Then compare the qualifying prices and terms across providers on networks that work for you. More gigabytes do not improve poor reception.
If your filters return no offers, relax a non-essential selection such as extra data or a feature, not an essential spending limit. Reduce the data allowance if your usage permits, look for a shorter commitment, or compare all SIM-only deals without assuming the cheapest introductory price is affordable over time. For a more detailed explanation of the low-cost market, see the separate guide to choosing SIM-only deals around £10; it uses a £10-or-less convention and should not replace the exact-price check on this page.
