It depends on your home provider, but generally, no. While Luxembourg is in the EU, Brexit has led many UK carriers to reintroduce roaming fees. For travelers from the USA, Switzerland, or Asia, roaming charges are almost certainly not free and can be exorbitant. A CheapESIM offers a predictable, low-cost alternative. By pre-purchasing a data plan for Luxembourg, you avoid bill shock and ensure transparent spending, often saving you significantly compared to traditional roaming.
