Best SIM and eSIM for Slovenia: data plans, Wi‑Fi and phone tips
Buy an eSIM from a pan‑European provider (e.g., Airalo, Holafly) before you leave; it works nationwide, costs about €10‑15 for 5 GB, and avoids the need to find a shop. Switch to a local prepaid SIM only if you need more data or a local number, and note that Alpine valleys have weaker signal.
