🌍 Balkans eSIM
One eSIM for the whole Balkan peninsula — the Adriatic beaches of Croatia and Montenegro, the old towns of Serbia and Bosnia, the mountains and monasteries of North Macedonia and Albania, plus Greece, Bulgaria, Romania, and Slovenia. The Balkans regional eSIM keeps you connected across all ten countries on one data plan, so a road trip from Ljubljana to Athens doesn't mean ten different SIM cards. Install before you go, switch on Data Roaming when you land, and keep your usual number for calls and texts. Data-only — ideal for maps, ferry and bus bookings, translation, and sharing the view.

Tip: 4G/LTE is widely available across Balkan capitals and the Adriatic coast. Mountain roads and remote national parks — Durmitor, the Accursed Mountains — can lose signal, so download offline maps for road trips. Offshore ferry crossings may slow down between islands.
