Mobile data in Slovenia: Ljubljana, Bled, the Alps and the caves
Slovenia is small, in the EU and usually part of a longer road trip with Italy, Austria or Croatia. For most Europeans roaming is simple; the questions are the mountains, the caves and whether one plan covers the whole route.

Will it work on my phone?
On iPhone: Settings → General → About, and scroll to EID. If there is an EID, your phone takes eSIMs. Every iPhone from the XS (2018) onwards does.
On Android: Settings → About phone → Status, and look for EID. If there is an EID, your phone takes eSIMs. Most Galaxy S20, Pixel 3 and later do.
It also has to be carrier-unlocked. If you bought it outright or your contract is over, it almost certainly is.

Coverage: Alps, lakes and caves
Coverage is strong in Ljubljana, Maribor, Piran and around Lake Bled and Bohinj. In the Julian Alps and on the way up Triglav it can drop on any network, and inside the Postojna and Škocjan caves there is no signal at all: take your tickets and photos offline before going in.
