To provision your CoreESIM, scan the provided QR code via your device's cellular settings (e.g., iOS: Settings > Cellular > Add eSIM; Android: Settings > Network & internet > SIMs > Add more). Label the new cellular plan for clarity, perhaps 'CoreESIM Hungary'. Once the profile is installed, navigate to your cellular data settings and ensure this new eSIM is selected for data. Crucially, verify that Data Roaming is enabled for the CoreESIM line. For optimal connectivity in Budapest, CoreESIM typically routes through primary carriers such as Magyar Telekom or Vodafone Hungary, ensuring robust 4G LTE or 5G access where available.
