DealPriceCheck
How we compare SIM deals
Last updated: 18 September 2026
DealPriceCheck is designed to make mobile offers easier to compare without hiding important terms behind a headline monthly price.
We compare selected providers and do not claim whole-of-market coverage.
Where our information comes from
Offer information is checked using provider product pages, provider terms and help pages, and other reliable source data.
We do not invent missing prices, roaming limits, eSIM support or contract terms.
What we compare
Where the information has been verified, DealPriceCheck may show:
- monthly price;
- introductory price;
- ongoing price;
- data allowance;
- minimum term;
- minimum contract cost;
- network;
- 5G availability;
- eSIM availability;
- EU roaming;
- annual price-rise information;
- checked date.
Not every field is available for every deal.
Checked dates
Mobile offers change frequently.
List pages show the latest checked date for the current dataset.
A checked date does not guarantee that a provider has not changed an offer since then. Always confirm the final price and terms on the provider website.
Best value
Best value compares effective monthly cost with useful data. Data gains taper after 100GB, so very large or unlimited allowances do not dominate. Small equal adjustments are then applied for a 30-day term, 5G, eSIM, roaming information and a stated no-price-rise policy. Commercial relationships do not affect the score.
Other deal labels
DealPriceCheck may also highlight offers using simple labels such as:
- Lowest price;
- Most data under £10;
- Flexible pick.
These labels are based on the current eligible offers and the rules used by the comparison.
Commercial relationships
Some outbound links may be affiliate links, and DealPriceCheck may earn a commission when a reader purchases after following one. This does not normally change the price you pay.
Commercial relationships do not affect standard organic ranking.
If a sponsored placement is introduced, it will be clearly labelled and separated from standard rankings.
Selected providers
DealPriceCheck compares selected providers.
A provider being absent from the site does not mean we consider it worse. It may simply mean that we have not yet added or verified its current offers.
