Will CoreESIM maintain a data signal within the extensive sub-sea tunnels of the Faroe Islands?

Yes, the Faroe Islands' advanced telecommunications infrastructure ensures comprehensive 4G/LTE coverage even within its renowned sub-sea tunnel network. Local carriers have implemented in-tunnel repeaters, guaranteeing continuous data connectivity throughout passages such as the Eysturoyartunnilin and Sandoyartunnilin. CoreESIM users can therefore expect uninterrupted access for navigation, streaming, or communication while transiting these subterranean routes, maintaining seamless digital services across the archipelago.
