When is the best time to activate my eSIMFlyer QR code for Ukraine travel, considering current air travel limitations?

Updated April 22, 2026

Given the current situation where direct flights into Ukraine are suspended, we recommend activating your eSIMFlyer QR code while you're still at home, prior to departure. This ensures your data is active and ready the instant you cross any land border, such as from Poland, Slovakia, or Moldova. Having immediate connectivity is crucial for navigation, checking real-time information, and coordinating ground transport as soon as you arrive, rather than scrambling for Wi-Fi at a border crossing.
