We recommend scanning and installing your DataESIM QR code prior to your departure, ideally while still in your home country. Given the current travel advisories and potential for immediate connectivity requirements upon entry into Ukraine, such as crossing land borders from Poland, Slovakia, or Hungary, having your data service pre-activated ensures instant network access. This eliminates any delay in establishing critical communications or navigation as soon as you arrive.
