CoreESIM connectivity is present in the above-ground reception and administrative areas of the Wieliczka Salt Mine in Poland. However, as you descend into the subterranean chambers, expect a significant attenuation or complete loss of cellular signal due to the geological structure. For connectivity deep underground, visitors typically rely on the mine's internal Wi-Fi network. Our network partners, such as Orange Polska, optimize for surface-level urban and suburban coverage.
