For Ukraine, it's most practical to scan and install your Truly Roaming eSIM QR code before you depart. Given current travel advisories and potential border crossing complexities, having active data immediately upon arrival, perhaps after crossing a land border from Hungary or Slovakia, is crucial for navigation, communication, and urgent updates. This way, you're connected from the moment you step foot in the country.
