Yes, it is highly recommended to acquire and install your CoreESIM for Budapest before your departure. Upon purchase, CoreESIM will provide a QR code or manual setup details via email. While connected to Wi-Fi at home, use your device's cellular settings to scan the QR code and install the eSIM profile. This ensures that upon landing at Ferenc Liszt International Airport (BUD), you can immediately enable the CoreESIM profile, establishing instant connectivity with a local Hungarian carrier like Telekom HU or Vodafone Hungary, without any delays.
