Advertiser Disclosure

Last updated: July 2026

We want it to be clear how Oakfield SIM works and how the service is funded, so you can weigh the information we give you appropriately.

How we're funded

Oakfield SIM is a free-to-use comparison and referral service. Corvan Mobile, the operator of this website, may receive a payment from a mobile provider if you choose to take out a deal following a call with our team. This is how we're able to offer the comparison call at no cost to you.

This does not change what we tell you

Any commercial arrangement we have with a provider does not change the accuracy of the information given to you on a call. Our team's role is to help you understand your options clearly, not to steer you toward any particular outcome.

We don't cover the whole market

We compare a range of monthly SIM-only deals from the providers we work with. We do not claim to compare every deal or every provider available in the UK market, and there may be other options available elsewhere that we do not discuss.

We are not a network operator

Oakfield SIM and Corvan Mobile are not a mobile network. Any contract for mobile service is between you and the relevant provider directly, on that provider's own terms.
