Will it work in Triglav National Park, the Julian Alps, and the Soča Valley?

The ETravelSim Slovenia eSIM works in the main Triglav National Park towns including Bled, Bohinj, Kranjska Gora, Bovec, and Kobarid, with reliable 4G at most accommodations and trailheads. Signal becomes very patchy on remote hiking trails, in deep alpine valleys, on ascents toward Mount Triglav, and at the higher mountain huts. The Soča Valley between Bovec and Kobarid has main-road coverage but drops on side trails and rafting access points — universal across all Slovenian carriers because of geography.
