Luxembourg's mobile network is served by three main operators: POST Luxembourg, Orange Luxembourg, and Tango. 4G LTE coverage is comprehensive across Luxembourg City, Esch-sur-Alzette, and all major towns, with strong connectivity along motorways and rail routes. Luxembourg is one of Europe's smallest countries at just over 2,500 square kilometres, which means coverage is generally consistent across most of the territory including the Ardennes forest region in the north and the Moselle valley in the east. Rural and forested areas may have slightly weaker signal in the most isolated zones. MobiSIM connects through supported Luxembourg networks to deliver fast and reliable data throughout your stay in this compact but well-connected country.
