Does my existing European (EU) or UK SIM card offer free roaming in Serbia, or should I consider eSIMAdventures?

It's a common misconception, but Serbia is not part of the European Union, which means the 'Roam Like at Home' policy doesn't apply there. If you're relying on your EU or UK SIM from carriers like Vodafone, O2, or EE, you'll likely face steep international roaming charges. eSIMAdventures provides a far more cost-effective and transparent solution for connectivity across Serbia, allowing you to explore historical sites in Belgrade or hike in the Tara National Park without unexpected bills.
