The WestESIM plan for Croatia is specifically configured for use within Croatian borders. While many travelers enjoy day trips to nearby destinations such as Mostar in Bosnia and Herzegovina or Kotor in Montenegro, it's important to note these countries are not part of the EU. Consequently, your data connection will discontinue upon crossing the border. For continuous connectivity across the Balkans, we recommend exploring our regional Europe-wide eSIM options.
