Greece has three networks: Cosmote, Vodafone and Nova. Athens and the larger islands are well covered; small islands, gorges and ferry crossings are where signal drops.
If you're island-hopping, the network a plan uses matters more than a small price difference.

Check your home plan first if your SIM is from the EU or EEA
Under the EU's "roam like at home" rules, a SIM from any EU country, Iceland, Liechtenstein or Norway can use its domestic allowance in Greece at no extra charge, subject to your operator's fair-use limit. If that's you, a travel eSIM may only make sense for extra data or if your allowance is small. Since 1 January 2026 the rules also cover Ukraine and Moldova.
UK SIMs are not covered by EU roaming rules
Since Brexit, UK networks set their own EU roaming charges, and many plans started after mid-2021 charge a daily fee. Check your contract: if you're paying a daily roaming fee, a 7-day eSIM is often cheaper for a week-long trip.
Islands, gorges and ferries
Holafly lists parts of the Pindus Mountains, routes on Mount Olympus, the Samaria Gorge, some small islands, remote coasts and boat journeys as places where coverage may be limited.
