Does EU 'Roam Like at Home' policy apply to Serbia with my European or UK SIM card?

Serbia is not a member state of the European Union, nor is it part of the European Economic Area (EEA). Consequently, the EU's "Roam Like at Home" regulation does not extend to Serbian networks. Standard international roaming charges will apply if you use an EU or UK-issued SIM card (e.g., from Vodafone, O2, Orange). These rates are typically substantially higher than CoreESIM's localized data packages for Serbia, making CoreESIM a more cost-effective solution.
