eSIM for Belgium — Instant 4G/5G Data Plans

Belgium's mobile network is served by three main operators: Proximus, Orange Belgium, and Base. 4G LTE coverage is comprehensive across Brussels, Bruges, Antwerp, Ghent, Leuven, Liege, and all major cities, with strong connectivity along intercity rail routes and motorways. The Ardennes region in the south, including forested and rural areas around Dinant, Spa, and the Luxembourg border, has generally reliable coverage in towns but may have weaker signal in dense forest and valley terrain. Belgium is a compact country, which means urban and suburban connectivity is consistently strong across most of the territory. MobiSIM connects through supported Belgian networks to deliver fast and reliable data whether you are in a city centre, on a train, or exploring the countryside.

Install your MobiSIM eSIM before arriving at Brussels Airport or your entry point so you are connected from the moment you land. Belgium's intercity trains are frequent and well connected, and having live data for SNCB train schedules and platform updates makes travel between cities significantly easier. Keep your home SIM active for calls while MobiSIM handles your data. Brussels has an extensive metro and tram network where real-time data access is useful for navigating connections. If you are driving into the Ardennes for hiking or visiting the Spa-Francorchamps circuit, download offline maps for those areas as signals can drop in forested valleys away from main roads.
