If your Greece eSIM connects to the mobile network but you cannot access the internet, the APN settings may need to be checked. Fortunately, most travelers never need to configure the APN manually because modern smartphones usually download the correct settings automatically.
However, if you experience problems after arriving in Athens, Santorini, Mykonos, Crete, Rhodes, Corfu, Zakynthos, Paros, Naxos, Milos or anywhere else in Greece, verifying the APN is one of the quickest troubleshooting steps.
Quick answer: the correct APN for your Greece eSIM is data.esim. Username and password should remain empty unless specifically instructed otherwise.

If the APN is missing or incorrect, your phone may show mobile signal while websites, apps and messaging services do not work.
