A SIM card at Heraklion Airport can provide a Greek number and in-person setup, but availability depends on the outlet and arrival time.
An eSIM can be installed before flying and avoids spending the first part of the Crete trip at a mobile counter.
NoveSIM plans are data-only and do not provide a Greek number, conventional calls or SMS.
Quick answer: Buy locally if you need a Greek number or staff assistance. Prepare an eSIM if you want data immediately after landing. Test the connection without airport Wi-Fi before starting the resort transfer.

Check the network, usable data, validity, hotspot rules and registration process. A large allowance is poor value if it expires before the return flight.
Prepare for travel beyond Heraklion
Choose a Greece eSIM, review Greek mobile networks and save the hotel pin before leaving the terminal. Reception can vary on mountain roads and remote beaches.
Test the selected line
Turn off Wi-Fi, load a webpage and verify maps. If eSIM data fails, use the Greece troubleshooting guide without deleting the profile.
