For travelers exploring the Balkans, it's vital to note that Montenegro, despite its European location and use of the Euro, is not a member of the European Union. Therefore, your 'Roam Like at Home' benefits from an EU or UK SIM card (e.g., Vodafone UK or Deutsche Telekom) will not apply. Relying on your home SIM for data in Montenegro will incur significant international roaming charges. WorldESIM offers a smarter, more predictable solution for connectivity, ensuring you stay connected from Kotor to Podgorica without unexpected costs.
