About your results

Our information is updated daily and checked regularly by human beings to ensure accuracy. Results should be taken as a guide only.
Please take care to check the availability, price, speed and limitations of all services on the mobile broadband provider’s website before you buy. If you find any errors, please let us know.

Speeds

* Speeds displayed are the maximum possible using the network and hardware offered, as indicated to us by providers.
Mobile broadband speeds vary greatly depending on your location and you may not be able to get the advertised speed in your location.
Please see the provider’s website for more information about coverage in your area.

Prices

Prices are for new customers only and include VAT and line rental unless otherwise stated.
Prices do not include: any cashback, gift cards or promotional gifts, charges for paying by an alternative method to direct debit, or any out of bundle costs such as data charges beyond stated limits.
Prices do not include roaming charges which may be applicable for using data outside the UK, even when a data allowance is available. Always check your provider’s roaming policy before using data abroad.
If your provider increases prices mid-contract, you have the right to leave without penalty, unless it was clearly stated at the time of sale.
¹ Some providers may increase monthly prices in line with the retail or consumer price index each year during the length of your contract. Please refer to individual provider’s terms and conditions before signing up.
² Standard prices outside of your contract period are subject to change.
³ Prices of 1-month/30-day contracts are subject to change after the initial period.

Providers

We aim to include as wide a selection of internet providers and deals as possible, but we do not include every provider on the market. For example, we may reject a provider where there is a high cancellation rate. Some providers may choose not to work with price comparison sites.
