United Kingdom · SIM-only
Compare UK SIM-only deals with a verified no-annual-price-rise policy. Filter live offers by price, data, contract length and network, then check the full payment schedule before choosing. A plan can avoid annual increases yet still move from an introductory discount to a higher, pre-agreed rate — or have different pricing conditions after a rolling period.
No current offers match these filters.
It means the provider says it will not apply its usual scheduled annual increase to the core SIM-only plan price during the period covered by that particular offer. It does not automatically promise a fixed bill for life. A time-limited introductory discount can end, additional usage can cost extra, and a rolling plan's future price may be governed by separate change-of-terms conditions.
You may also see these described as fixed-price SIM-only deals. That description is most meaningful when the provider specifies the price, the protected period and any exceptions; a 30-day no-annual-rise policy is not automatically equivalent to a 24-month price freeze.
The two questions that matter most are: What price is protected, and until when?
| Wording you may see | What it means for your choice | What the wording does not settle |
|---|---|---|
| No mid-contract price rises on a fixed-term SIM | No scheduled annual uplift to the agreed core price or disclosed payment schedule during the stated minimum term | Introductory-rate expiry, other charge categories, or pricing after the term |
| No annual price rises on a 30-day rolling SIM | No standard scheduled yearly increase under the quoted plan policy | Whether future rolling renewals can be repriced following the plan's notice terms |
| Discounted first few months | The advertised initial payment applies only for the specified periods | Whether the later regular payment still fits your budget |
| Fixed core-plan price | Protection of the basic subscription within the promise's scope | Roaming, out-of-allowance use, international or premium calls, add-ons and other extras |
This page does not treat every rolling SIM as a no-rise SIM. A deal enters the live comparison only when our current offer information contains explicit, verified no-annual or no-mid-contract price-rise wording. Likewise, a provider's general claim does not prove that every plan it sells has the same protection. DealPriceCheck compares selected offers, not the whole market.
The strongest choice depends on how long you want to keep the plan — and what freedom you are prepared to give up in return for certainty.
Filter the live offers by your preferred contract length. A fixed-term plan with an explicit no-mid-contract-increase promise is the more relevant option if you want the agreed core-plan price schedule protected for that commitment. Check the minimum contract cost, any promotional stages, and whether you are comfortable staying if a cheaper tariff appears elsewhere.
There are examples of this approach among currently featured providers. iD Mobile shows SIM-only options with no annual price rises across different lengths; Asda Mobile promotes no mid-contract rises on longer pay-monthly SIM contracts. The precise terms of the card you open — not a network-wide slogan — are what you should buy on.
The trade-off: More defined price certainty can come with a longer minimum commitment and potential early-exit charges. Confirm coverage before committing for a year or two.
Select 30-day rolling if you are testing signal, may move house or simply do not want a long minimum commitment. Compare the current price and the amount charged after any sign-up promotion. Then check how much notice you must give to cancel and how the provider can change the price of a later renewal.
An advertised absence of annual rises is valuable, but a 30-day plan should not be treated as a two-year price guarantee. If avoiding a long tie-in is your overriding priority, our separate no-contract SIM deals comparison covers that broader intent, including offers without a verified no-rise badge.
The trade-off: You can respond to changes more easily, but must be willing to review the price occasionally.
Use the Price filter as a starting point, then read the schedule on shortlisted cards. A price that looks affordable for month one may rise to the already disclosed standard rate when an introductory discount finishes. That is a different event from an annual contract uplift, but your bank balance feels both.
If you have an absolute £10 ceiling, check whether the regular, not just the introductory, payment remains under it. Our SIM-only deals under £10 page is the broader budget-first comparison; this page is for offers that also satisfy our no-rise evidence requirement.
The trade-off: A lower starting price is not necessarily a lower price over the period you intend to stay.
Here is the most important arithmetic for a no-rise comparison. Two plans can both avoid scheduled annual uplifts and still cost quite different amounts over the same minimum term.
Illustrative example only — these are invented 24-month schedules, not current UK deals:
| Plan A: introductory offer | Plan B: flat monthly price | |
|---|---|---|
| Months 1–6 | £6 × 6 = £36 | £10 × 6 = £60 |
| Months 7–24 | £12 × 18 = £216 | £10 × 18 = £180 |
| Total subscription cost | £252 | £240 |
| Effective cost per month | £10.50 | £10.00 |
Plan B costs £12 less, despite Plan A advertising a much lower first payment. If the step to £12 was specified at sign-up, it need not be an annual price rise at all. It is still a cost you must budget for.
For a fixed minimum term, calculate:
Total cash cost = all actual subscription payments at the disclosed rates + mandatory upfront charges − any separate, unconditional cashback or credit not already reflected in those payments.
Do not subtract a promotional discount twice. If the monthly payments in your calculation already show the reduced introductory price, that saving is already included.
Treat cashback that requires a separate claim, conditional rewards and temporary bonus data differently from guaranteed cash savings. If an offer promises extra data only for a promotional period, the allowance can change without the monthly charge changing. Look at the offer details, not just the price-rise label.
For a rolling plan, the “minimum term cost” may represent only one 30-day period. It is not the same as a dependable twelve-month cost. You can estimate twelve payments using disclosed promotional and regular rates, but do not claim certainty about unguaranteed future renewals. Similarly, do not rank a 12-month total against a 24-month total without accounting for the other twelve months.
No. Avoiding rises makes costs more predictable, but it does not automatically produce the lowest total bill.
In another hypothetical 24-month comparison, a plan at £9 for twelve months and a clearly pre-agreed £10.50 for the next twelve costs £234. A competing no-rise plan at £10 for all 24 months costs £240. The first plan still works out £6 cheaper, even though its subscription increases. Both examples exclude usage extras and assume identical allowances, coverage and contract terms.
That is why our recommendation is to compare price protection and total cost, not to pay an unlimited premium for a reassuring label. If the cheapest overall tariff matters more than a no-rise policy, use the full UK SIM-only comparison and inspect each plan's price-rise terms.
The offer snapshot checked on 19 October 2026 contained a mix of rolling subscriptions and longer fixed terms. These provider examples explain the relevant contract models, not guaranteed prices, permanent product availability or a ranking of the cheapest networks. The live cards above may change as offers are refreshed.
| Provider (offers checked 19 October 2026) | What to pay attention to | Evidence or provider terms |
|---|---|---|
| iD Mobile | A choice of 30-day and longer SIM-only commitments; compare the plan length against your need for price certainty | SIM-only range and no-annual-rise labels |
| Asda Mobile | Fixed-term contracts with no-mid-contract-rise wording; check the commitment and the price after it ends | Pay-monthly SIM-only terms |
| Lyca Mobile | Some qualifying offers have an introductory price followed by a disclosed standard rate; calculate the complete schedule | SIM-only offers and terms |
| giffgaff | Both rolling and 18-month options appear. As checked in October 2026, the fixed-term price-lock promise is qualified by a purchase deadline (before the end of 2026), and bonus data has separate conditions | 18-month SIM-only offer details and footnote |
| VOXI | Its SIM-only range is rolling but its plan pages also say “Price locked”. Check that specific promise rather than assuming every rolling plan is identical; note temporary extra-data promotions and separately purchased roaming passes | SIM-only plans and price wording |
Do not assume that every plan from any one of these operators qualifies. The live card's price-rise field and the final provider order summary should agree on the exact offer you select.
An instructive exception elsewhere in the market is Tesco Mobile. As checked in October 2026, its official pricing policy protects the basic monthly usage price of eligible Clubcard Price deals during their minimum term, while its non-Clubcard Price deals can have stated annual increases. This illustrates why a company-wide “no rises” label would be misleading. It is not a claim that Tesco deals are currently listed above.
Most no-rise claims concern the core subscription: the monthly payment for the included calls, texts and data, subject to any disclosed introductory phases. They should not automatically be read as promises about the cost of every extra service.
Examples to examine before paying include:
This distinction is visible in the wider market: Lebara's no-price-rise disclaimer and plan wording distinguish its core SIM-only price policy from international minutes, roaming and PAYG rates or allowances, which may change. That does not mean Lebara is currently one of the qualifying cards on this page; it is a concrete example of why the scope of the promise matters.
Check EU roaming, eSIM and 5G on each live card, then confirm allowance limits and coverage on the provider's website. “EU roaming included” is not a promise of unlimited EU data; “5G included” does not establish adequate signal where you actually use your phone.
If roaming is your deciding factor, compare SIM deals with EU roaming. If you need to activate service without a plastic SIM, see UK eSIM deals. For a high-data requirement, the unlimited SIM comparison lets you consider allowances first and verify price-rise terms on each shortlisted deal.
Ofcom's rules for new consumer contracts from 17 January 2025 prohibit in-contract price-rise clauses based on inflation or percentages. They do not ban all annual increases. Where a provider includes a scheduled increase, the amount must be set out clearly in pounds and pence, with its timing explained before you sign. Contracts agreed before that date may have different clauses.
Ofcom's guidance says that if the contract does not state how much the price can rise and the provider increases it, or if the increase exceeds the amount specified, the provider must give at least 30 days' advance notice and offer 30 days from that notice to leave without exit fees. That is not an unrestricted right to cancel any contract simply because a properly disclosed scheduled increase takes effect.
A plan with an accurately disclosed annual increase can therefore be lawful. This page is about a different commercial choice: comparing SIM-only offers with an express no-annual or no-mid-contract-rise policy. For the wider regulatory picture and policies of the larger networks, use our separate UK SIM-only price rises guide rather than treating this deal page as a legal manual.

Yes. Some UK SIM-only offers explicitly exclude scheduled annual or mid-contract price increases. The cards above use verified policy wording, but the protection's length and scope depend on the specific plan, not the provider's name alone.
Not necessarily. The core price can have a pre-agreed introductory stage and later standard rate. Out-of-allowance charges can also alter the bill. On rolling deals, future renewals may be subject to price changes permitted by the plan's terms.
Potentially. A no-annual-rise policy does not automatically guarantee a multi-year price on a monthly renewal. Check the provider's notice, cancellation and future-price conditions. The main benefit of a rolling plan is the option to leave with a short commitment.
It may be moving from a disclosed introductory discount to its ordinary subscription price, rather than applying a yearly increase. Add every stage of the schedule to assess the total cost. If the advertised policy conflicts with the checkout terms, clarify it before purchasing.
No. A longer freeze offers more defined price certainty, not an automatic saving. A cheaper rolling tariff or a contract with a disclosed rise can cost less over the same period. Compare like-for-like data and coverage, the full cost, and any penalty for leaving early.
This is a selected, evidence-based catalogue. A rolling term on its own does not qualify, and the absence of a provider does not prove that all its plans increase annually. Eligibility is tied to verified wording for individual offers in the current dataset.
Do not assume it does. The basic subscription may be protected while international rates, roaming charges, out-of-allowance usage or separately priced extras change. Review the plan's exclusions and the specific countries you need.
In certain circumstances. Under Ofcom's rules, if the provider raises the price without a quantified increase in the contract, or exceeds the specified increase, it must give advance notice and a 30-day opportunity to exit without fees. An increase that was clearly specified when you signed up does not create that right solely by taking effect.
