DataESIM offers excellent signal quality at the entrance points and panoramic viewpoints surrounding the Casemates du Bock in Luxembourg City. This allows for high-speed uploads of scenic photos and seamless external communication. However, once you venture deep into the subterranean tunnels and defensive galleries, the thick rock and historical fortifications will significantly attenuate cellular signals. Expect connectivity to be lost or severely degraded within the interior sections of the Casemates.
