This specific plan is valid only within Bulgaria (and the EU). This is the most important question for Balkan travelers. If you take a bus from Sofia to Istanbul (Turkey), Belgrade (Serbia), or Skopje (North Macedonia), your connection will stop at the border as they are not in the EU. For this multi-country trip, we highly recommend our Europe Regional eSIM, which covers both EU and non-EU Balkan countries.
