When does an eSIM beat my plan’s EU roaming?
When your network charges a daily fee in Greece, or limits your roaming data. Island hopping uses more data than people expect, for ferry tickets and maps.

Before you buy: straight answers
Will it work on the islands and ferries?
Yes on the islands, on the Vodafone and Wind networks. At sea, signal comes and goes, so save ferry tickets before you sail.
What if my phone joins a Turkish network?
Near Kos, Rhodes and Samos it can. Turn data roaming off for your UK SIM so Turkey roaming can’t start a charge.
What your trip to Greece costs
Set your trip length and how you use your phone. eSIM bars are data-only plans that cover the whole trip; UK network bars use your UK allowance and include calls and texts. EE and O2 don’t publish a price for Greece that we can check, so they aren’t charted.

See day passesHow we choose these plans
For each trip we pick the current plan that costs the least while lasting the whole trip and gives about 0.3 to 0.7 GB a day, enough for maps, messages and social media. A plan may last longer than the trip. Everyone uses data differently, so check your phone’s recent data use. “Best value” only appears when that plan also costs the least per GB of all the plans that fit.

Your UK network in Greece
Greece is in the EU, so check your plan first: it may already include roaming there. What each network publishes for Greece, and a week of it:
| Network | What it charges | 7 days | Compare |
|---|---|---|---|
 EE | Varies by plan EE doesn’t publish one price for every country: it prices roaming by destination, plan and start date. Check EE’s roaming tool for Greece. | No published price | EE roaming |
| O2 | O2 Europe Zone O2 treats its Europe Zone separately from O2 Travel, and what you pay in Greece depends on your plan. Check your plan in My O2 before you go. | No published price | O2 roaming |
| Vodafone | Zone B £16 for an 8-day pass or £21 for 15 days in Zone B. Uses your UK calls, texts and data, up to 25 GB a month. | £16.008-day pass | Vodafone in Greece vs eSIM |
 Three | Go Roam in Europe £2.75 a day in Go Roam in Europe (£2 on plans from 2021 to 2025), or £12 for a 7-day pass. Unlocks your UK calls, texts and up to 12 GB of your UK data. | £12.007-day pass | Three in Greece vs eSIM |

Graba SIM vs Airalo: the same plans, side by side
Plans with exactly the same data allowance and validity for Greece, both data-only and priced in pounds. Coverage and networks can differ, so check the plan details before you buy.
Highlighted: the lower price for each plan. Holafly sells unlimited data only, priced in US dollars, so it isn’t in this like-for-like table.

Know before you go
- Island ferries spend hours at sea, where signal comes and goes. Download tickets and boarding passes before you sail.
- Greece is in the EU, so your UK plan may already include roaming there, free or for a daily fee. Check it before you buy an eSIM.
- On Rhodes, Kos, Samos and Lesbos your phone can join a Turkish network near the coast. Turkey is outside the EU, so check which network you are on.

Questions about Greece
Does a Greece eSIM work on the islands?
Yes. The plan uses Greek networks, which cover the main islands and their resorts. Signal comes and goes on ferries between islands and on remote beaches.
Will my phone connect to a Turkish network on Kos or Rhodes?
It can, near the coast. Turkey is outside the EU, so your UK network may charge more there. Turning off data roaming on your UK SIM, and using the eSIM for data, avoids that.
Is a travel eSIM cheaper than roaming in Greece?
For a week with about 0.7 GB a day, the Graba SIM 5GB, 30 days plan costs £8.99, less than each published UK network option for Greece (the lowest is Three at £12.00). UK network prices include calls and texts; the eSIM is data only.
What do UK networks charge in Greece?
EE: EE doesn’t publish one price for every country: it prices roaming by destination, plan and start date. Check EE’s roaming tool for Greece. O2: O2 treats its Europe Zone separately from O2 Travel, and what you pay in Greece depends on your plan. Check your plan in My O2 before you go. Vodafone: £16 for an 8-day pass or £21 for 15 days in Zone B. Uses your UK calls, texts and data, up to 25 GB a month. Three: £2.75 a day in Go Roam in Europe (£2 on plans from 2021 to 2025), or £12 for a 7-day pass. Unlocks your UK calls, texts and up to 12 GB of your UK data.
