Who we are. Keyanok is an independent information and guidance service for United Kingdom mobile customers. We are not a mobile network. We have no affiliation with, endorsement from, appointment by or connection to Three, EE, O2, Vodafone, Sky Mobile, Tesco Mobile or any other provider, and no commercial arrangement with any of them. We do not sell, supply, arrange or broker SIM cards, contracts, handsets or services of any kind, and we take no commission. Everything on this site is general information; a provider’s own current terms always take precedence.
