Mobile

Sure (Guernsey) Limited, operating as Sure Mobile, is a prominent mobile network operator serving the island of Guernsey, a self-governing British Crown Dependency located in Europe. Identification of mobile networks globally relies on numerical codes, and Sure Mobile is cataloged under Mobile Country Code (MCC) 234, shared with the United Kingdom, and a unique Mobile Network Code (MNC) of 55. This unique identifier allows mobile devices to connect, authenticate and access Sure’s network services on the Channel Island. As one of the primary telecommunications providers in Guernsey, Sure Mobile offers a comprehensive suite of services including voice calls, SMS messaging, and mobile data. In a competitive market alongside JT (Guernsey) Limited, Sure invests significantly in network infrastructure improvements, including 4G and potentially 5G deployments, to provide reliable and high-speed connectivity to both residents and visitors within the Guernsey region. Sure plays an important role in the island's communications, and provides services for consumers, businesses and governments, to ensure they can have easy access to telecommunications services.
