Networks our Greece plans use: WindVodafone
- 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.

Three in Greece: questions
How much does Three roaming cost in Greece?
£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. For a trip, that is 3 days: £5.00 (3-day pass); 7 days: £12.00 (7-day pass); 14 days: £24.00 (14-day pass).
Is a travel eSIM cheaper than Three in Greece?
It depends on the trip. Comparing Three’s lowest published option with a Graba SIM plan of about 0.7 GB a day: 3 days, Three is £0.75 less; 7 days, the eSIM is £3.01 less; 14 days, the eSIM is £8.01 less. Three’s price also includes your UK calls, texts and up to 12 GB of your UK data.
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.
