Frequent flyers often make this common mistake: assuming 'Europe' means free roaming. While geographically in Europe, Serbia is not part of the European Union, meaning the 'Roam Like at Home' policy doesn't apply. Your existing EU or UK carrier (like Vodafone, O2, or T-Mobile) will likely hit you with exorbitant international roaming charges. eSIMFlyer provides a cost-effective, dedicated data plan for Serbia, ensuring you stay connected without bill shock, perfect for exploring Belgrade or beyond.
