When exploring the historic Casemates du Bock in Luxembourg City, your eSIMBuy deal will provide excellent signal at the entrances and the various panoramic viewpoints. This is great for sharing those initial photos and orienting yourself. However, as you venture deep into the ancient, thick rock tunnels and defensive galleries, expect your connection to likely drop. The sheer depth and historical construction are amazing, but not always conducive to modern mobile signals. Plan to enjoy the history without constant digital distractions in the deepest parts.
