Is roaming included at no extra cost in Montenegro for my European (EU) or UK SIM card, as CoreESIM users might inquire?

CoreESIM advises that Montenegro, despite its geographical location in Europe and use of the Euro, is not an EU member state. Therefore, 'Roam Like at Home' (RLAH) policies applicable to EU/EEA citizens with carriers like Vodafone UK or Deutsche Telekom do not apply. Users of EU or UK SIMs will incur standard, often high, international roaming charges. CoreESIM provides a dedicated, cost-effective data solution for Montenegro, circumventing these prohibitive roaming fees.
