Does WorldESIM work inside Luxembourg's Casemates du Bock?

With WorldESIM, you'll generally find excellent signal at the entrance and panoramic viewpoints of the Casemates du Bock in Luxembourg City. However, due to the thick rock walls and historical construction, the connection is likely to diminish or be lost as you delve deeper into the extensive underground tunnels and defensive galleries. We recommend enjoying the historical atmosphere and reconnecting once you emerge into the open air.
