Do I need HotelESIM data for the Mobiliteit.lu app, even with free transport?

Yes, even though public transport is free nationwide in Luxembourg, your HotelESIM's active mobile data is essential for an efficient travel experience. You'll need it to use the Mobiliteit.lu app, which provides real-time schedules, identifies the correct bus or train platforms, and helps you navigate seamlessly through Luxembourg City. HotelESIM ensures you always have the live information you need, complementing your hotel's connectivity and enhancing your exploration.
