Will my EU or UK-based SIM card incur roaming charges when using DataESIM in Montenegro?

Deploying DataESIM in Montenegro means your primary EU or UK SIM card will be subject to its carrier's standard international roaming rates, which are typically high. Montenegro, despite its European location and use of the Euro, is not an EU member state. Consequently, the "Roam Like at Home" directive does not apply. Operators like Vodafone UK, Deutsche Telekom, or Three Ireland will impose significant daily or per-MB charges. DataESIM offers a cost-effective, high-data alternative, ensuring predictable and robust connectivity in locations such as Podgorica or Kotor without unexpected bills.
