Common questions about eSIM for Greece
Does the eSIM work on the Greek islands?
Yes. It uses Cosmote, Vodafone and Nova, which cover Santorini, Mykonos, Crete, Rhodes, Corfu and most inhabited islands with strong 4G and 5G in the larger towns.
Is a Greece eSIM good for island hopping?
Very — one eSIM stays connected as you move between islands, automatically picking the best available network, so you don't buy a separate SIM on each island.
Should I get a Greece-only or a Europe eSIM?
Choose Greece-only if you're staying in Greece; pick a Europe eSIM if your trip also covers Italy, France or other EU countries on the same journey.
Can I install my eSIM before I travel to Greece?
Yes. In most cases you can install the eSIM before departure and activate data when you arrive or when your package instructions recommend it.
Can I keep my regular SIM while using data in Greece?
Usually yes, if your phone supports dual SIM or dual eSIM. Many travelers keep their primary SIM for calls and use NovaSIM for data.
