Compare eSIMs for Balkans 2026

A trip linking Bulgaria, Greece and Croatia is the kind of itinerary a Balkans regional plan is generally suited to: availability is spread fairly evenly across its patchwork of mostly small states, rather than clustered in just a few markets. A regional plan therefore behaves broadly as buyers expect, although each plan’s country mix still needs checking. The practical choice is between one regional plan and two or three single-country plans, usually decided by how many borders the itinerary crosses.
