This specific plan is valid only within Serbia. This is crucial for "Balkan Tour" travelers. If you take a bus from Belgrade to Sarajevo (Bosnia), Kotor (Montenegro), or Zagreb (Croatia), your connection will stop at the border. For a seamless multi-country road trip, we highly recommend our Europe Regional eSIM, which covers all these countries with one plan.
