Useful travel information
A few details that help before and during your trip.
Mobile coverage in Slovenia
Slovenia's mobile network is served by three main operators: Telekom Slovenije, A1 Slovenia, and Telemach Slovenia. 4G LTE coverage is comprehensive across Ljubljana, Maribor, Celje, and all major cities, with strong connectivity along main motorway and rail corridors. Lake Bled and Lake Bohinj have reliable coverage in resort and town areas, with signal weakening on higher Triglav National Park hiking routes and alpine terrain. The Soča Valley has coverage in Bovec and main towns, with signal varying in remote valley and mountain sections. The Karst region around Postojna and Lipica has solid coverage in tourist areas. Some remote Julian Alps terrain above 2,000 metres may have limited signal. MobiSIM connects through supported Slovenian networks to deliver reliable data throughout your stay.
