Is roaming free in Luxembourg with my UK or US SIM card?

The cost of roaming in Luxembourg, an EU member, depends on your home country and mobile provider. For travelers from the UK, roaming charges have often been reintroduced post-Brexit. Visitors from the USA, Switzerland, or Asia will almost certainly incur significant and costly roaming fees. A HotelESIM offers a predictable and budget-friendly alternative, providing transparent data costs without the worry of unexpected charges, allowing you to stay connected affordably and conveniently, much like using your hotel's Wi-Fi.
