An eSIM is the most convenient way to stay connected when traveling in Greece. Gone are the days that we need to find a local phone shop and swap a physical SIM card! ETravelSim really stands out as the best eSIM for Greece if you’re traveling on a budget. It also has a standout feature that gives you a local phone number, which may be more useful than you think. Here’s more about all its features, and a 15% discount on your first eSIM.

The best eSIM for Greece: ETravelSim
Whether you’re heading to Greece for a quick getaway or a longer island-hopping adventure, ETravelSim is 100% worth checking out. Here are its top perks, and why I think it’s the best eSIM for Greece. From the option to add a local number to how its pricing stacks up to competitors, it’s a solid choice for budget travelers.
ETravelSim is the best eSIM for Greece because you get a local number
This is the real reason I think ETravelSim is the best eSIM for Greece: it gives you more than just data.
You might think you don’t need anything except for the internet. And, for survival purposes, that’s true. But not having a local number has bitten me in the butt a couple times now.
It can be super annoying when you’re trying to make a reservation and the only contact given is a local phone number. (But that’s also how you know the food is going to be good.) Trying to book a spot on the only ferry moving between Zakynthos and Kefalonia also required a local phone call.
Use NAOMI15 in the promo code box when you pay for 15% off.
If you pay a little extra (like, a few euros), you can make calls with your ETravelSim plan. Super handy in situations where WhatsApp won’t cut it, which happens more than you might think!
Note: It’s not local, local. It’s a +44 UK number, but that won’t matter. The key is that you’ll be able to make and receive calls/texts within Europe. You also have to select this, it doesn’t come standard with every plan.
ETravelSim has super flexible data plans
You likely don’t need 25GB of data for a two-week holiday. Compared to the old-school chip, Vodafone’s tourist SIM gives you 25GB for 30-days at €20. It’s not terrible, but if you’re just there for a short time or you’re not constantly streaming videos, 25GB is a bit overkill.
One of the best things about eSIMs (imo) is that they’re so much more flexible. ETravelSim has a range of options, from 1GB to unlimited data plans and the ability to get a local number for calls and texts for a few bucks more. If you start with 5GBs and overdo it with maps, messages, and accidental Instagram scrolling, you can top up another 1 or 2 GBs rather than having to commit to another €20 for 25GB.
And if you are a heavy data user (no judgment, samesies), ETravelSim has unlimited plans too. Nice when you don’t even have to think about your usage. Google Maps to your heart’s content.

Per Proximus Global, a 2025 survey revealed that only about 33% of people around the world know what an eSIM is. So you’re already ahead of the curve!
Ready to go when you land
This is a benefit of all eSIMs, but still worth highlighting.
The last thing you want to do when you arrive is figure out how to buy a SIM card in a busy airport or ferry terminal, especially if you don’t speak Greek! It’s also a scam waiting to happen — airport SIM cards are notoriously overpriced. And if you don’t get one on arrival, you have to find your way to your accom without an internet connection the old-fashioned way.
Getting an eSIM in Greece cuts out that tedious step and you can activate it as soon as you arrive. All you need is a minute with a Wi-Fi connection (airport Wi-Fi works) so you can tap a few buttons and get it set up. Boom—instant connection.
The best eSIM for Greece... and beyond!
ETravelSim’s regional Europe plan is a perfect option if you’re doing some country hopping. It’s only marginally more expensive for the regional plan. (Like, $10 Greece vs. $12 Europe for 5GBs of data and 100 mins of local calls.)
Always make sure you check the list of compatible countries before you commit. But it works pretty much everywhere.
If you’re flying in from Spain, taking the ferry to Albania, or continuing on to Turkey, the regional eSIM covers you. (Including your local phone number.)
This is the complete list of 36 countries included in the Europe eSIM plan (as of June 2025):
Albania, Austria, Belarus, Belgium, Bulgaria, Croatia, Czech Republic, Denmark, Estonia, France, Finland, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Liechtenstein, Lithuania, Luxembourg, Netherlands, Malta, Norway, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey, United Kingdom, Vatican City.

Airalo is another major player, but I can’t recommend it right now. They’ve had some serious security concerns and a lot of people say their accounts were hacked and credit cards were charged. Most aren’t getting any refunds. I’d avoid it like the plague, at least for now.
