Bought the wrong plan? An unused, never-activated eSIM can be refunded in full within 30 days of purchase. See our refund policy for the full terms.
Fixed data plans give you a set amount of data, for example 1 GB or 5 GB, to use at full speed for the whole plan period. When it runs out, you top up or buy again. Pick this if you know roughly how much you'll use.
Unlimited plans never run out during the plan period, but each day includes a high-speed allowance. Once you use that day's allowance, you stay connected at a reduced speed until it resets 24 hours after you activate the eSIM. Pick this for heavier or less predictable use. A fair-use policy applies.
Pay As You Go is not a plan at all. You add credit once and it comes off by the megabyte at the local rate as you use it, so you never pay for data you do not finish. Credit never expires, data pauses when the balance hits zero, and the same eSIM keeps working across every country we cover. It costs more per gigabyte than a plan, so pick this for light or hard to predict use rather than heavy days.
Add your other stops and we check whether one regional eSIM costs less.
Greece's three mobile networks are Telekom, Vodafone and Nova. Telekom is the network long known as Cosmote, and it appears on phones as TELEKOM.GR, so any of these three names on your screen means you're on a Greek network.
On islands close to the Turkish coast, such as Lesvos, Samos, Kos or Rhodes, your phone can pick up a Turkish network without you noticing. Ireland's regulator warns that this happens in border areas, and Türkiye is outside the EU roaming zone, so check how your plan treats Türkiye before you go.
Greece's 112 system warns people about wildfires, floods and other dangers with alerts sent to phones in the affected area. The UK government advises making sure emergency alerts are switched on in your phone's settings and keeping the phone with you.

Your Greece eSIM connects automatically to Cosmote, Vodafone, and Nova, switching to the strongest available signal. Cosmote is the most reliable across the islands.
