Seeking the best eSIM for Greece to accompany your vacation at sea? You need one if you want to stay connected without paying roaming rates. Taking photos and posting them on social media lets everyone know how sizzling hot you are in a swimsuit. But without a trusted eSIM for Greece, that gets expensive fast.
Worth knowing before you book: if you’re flying in from the US, the UK or Canada, your domestic plan will not follow you, and you’ll be billed at international rates from the moment you land. EU visitors keep their bundle under roam-like-at-home rules. We retested over 20 providers across Greece, and these five are the ones worth buying in 2026.

Best eSIM for Greece: Best Options Fully Reviewed
We compared all five on price, data allowances, network access, tethering and plan length. Here’s how they landed.
1. Ubigi

Pros
- Cheapest unlimited data
- Unlimited data sharing
- Some of the fastest speeds
- Encrypted data connection
Con
- No local phone numbers
Set sail for Greece with the best eSIM here. Ubigi sells one-off plans you can top up if you run dry, though you may not need to: unlimited data for seven days is only $24, rising to $39 for 15 days and $55 for 30. That monthly figure undercuts Holafly’s $74.90 by $20.
The best seller is actually the 25 GB plan at $22 for 30 days. Either way, Ubigi delivers 4G and 5G through Nova, one of Greece’s strongest networks. Testing it mostly on the coast, we had zero issues with Viber video calls, mobile gaming or Netflix.
Setup is a QR code and you’re done. After that, you can share your connection by using your phone as a hotspot, without limits. Support runs 24/7, and Ubigi’s connections are encrypted, letting you browse with either a local IP or your home-country IP, so your usual apps and services work without restrictions or added latency.
Ubigi is one of the best eSIM providers overall, with global and regional plans covering 200+ locations. It has also teamed up with Gizmodo for a 10% discount on your first purchase using the code GIZMODO. More in our Ubigi review (it’s also the best eSIM provider in Spain).
2. Saily

Pros
- Cheapest entry plan at $3.82
- Ad blocker and virtual location
- Airport lounge access in the app
- 30-day activation period
Cons
- Unlimited plans throttle after 5 GB a day
- No Greek phone number
Saily makes the trip easier and it’s cheaper than it used to be. The entry plan is $4.49 for 1 GB over a week, or $3.82 with the GIZMODO code, the lowest way onto a Greek network. Want more? 10 GB for 30 days costs $21.99, or $18.69 discounted, and 5 GB runs $13.99, or $11.89.
Unlimited data is $48.99 for 15 days, which the code takes to $41.64. One caveat: that plan gives you 5 GB per day at full speed, then keeps you connected at 1 Mbps. Perfect for maps and beach-side scrolling, less so for streaming.
Every plan bundles security features, including an ad blocker and a virtual location that hides your whereabouts. Speed-wise, Saily leans on LTE with a pinch of 5G where available, and in our tests it matched Ubigi for streaming, gaming and video calls.
New in 2026: the app now sells airport lounge access and fast-track security passes at checkout, with no subscription, which is welcome on a long connection through Athens. Saily was named “Rising Star” at the MVNOs World Congress in Amsterdam in June 2026. You get a 30-day activation window, unlimited data sharing, and 24/7 live chat inside the app. Current deals are on our Saily promo code page.
Tip: Through Gizmodo, you can save 15% on all Saily plans by using the promo code GIZMODO at checkout.
3. Holafly

Pros
- All three Greek networks
- Unlimited data with no speed cap
- Industry-leading speeds
- Instant activation
Cons
- 500 MB/day sharing limit
- Expensive for longer stays
Holafly is a standout eSIM for Greece and one of the best eSIM providers for Europe. It’s affordable on short stays, at $3.90 for a day of unlimited data, and the rate eases as you extend: $27.30 for seven days, $50.90 for 15 days, and $74.90 for 30 days, which is $20 more than Ubigi.
Two things justify that premium. First, the data is genuinely uncapped: no 5 GB daily allowance, no drop to 1 Mbps, unlike Saily. Second, and this matters enormously in a country of islands and mountains, Holafly reaches all three Greek operators: Cosmote, Nova and Vodafone Greece. Ubigi and Airalo both ride Nova alone. When the ferry rounds a headland and the signal thins, that redundancy is what keeps you online.
In testing, Holafly breezed through streaming and gaming, with no-lag video and audio calls, and activation was instant the moment we landed.
The catch is tethering, capped at 500 MB per day, which isn’t enough for group travel. Its 24/7 live chat is the best we tested, but that sharing limit takes the shine off. Holafly is at its best on a one-week trip.
4. Airalo

Pros
- Ideal for group travel
- 5G data for fast speeds
- Very affordable
Cons
- No Greek phone number
- Slow-to-respond support
Airalo is known for plan flexibility, which makes it a popular eSIM for Greece. Start at $4 for 1 GB over three days, or take 3 GB for $7.50. Plans stretch to seven, 15 and 30 days, with up to 50 GB. And there’s unlimited data from just $10.50 for three days.
Five days cost $17.50, and a week is $24. That’s not much, especially since Airalo lets you share data without limits. One eSIM for Greece, and you and your friends are all online. Speeds are good too: Airalo runs on 5G from Nova.
Connections were smooth, with low latency for mobile gaming and calls. Support is the slowest of the five to respond, which is the main gripe. We’d also like plans with minutes and SMS, which Airalo sells in other countries but not here. Otherwise it’s hard to fault, especially at this price.
5. Jetpac

Pros
- Cheapest entry plan at $1
- Free data for essential apps
- Subscriptions for avid travelers
Cons
- 4G only, no 5G in Greece
- Slower than the top three
Jetpac is widely used in Greece for one reason: free data for WhatsApp Chat, Uber, Grab and Google Maps, which keeps working after your allowance runs out. That’s genuinely useful on unfamiliar ground. Pricing starts at $1 for 1 GB over four days, the cheapest entry here, though we’d take the 3 GB plan for seven days at $9.
Jetpac recommends 30 GB for 30 days at $24.99, and unlimited data runs $33.99 for ten days, which is decent value against Holafly’s $50.90 for fifteen. It relies on Nova and Vodafone for 4G, with solid if unspectacular speeds. Stability was never an issue and we never lost connection on the road.
Jetpac also runs subscriptions, JetFlex and JetPro, for frequent travelers who want coverage across 100+ countries, free lounge access on delayed flights and other perks. It’s well regarded among the best eSIMs for international travel. Add 24/7 support, easy activation and unlimited sharing, and it earns its place.
Summary: The Best eSIM for Greece
Picking the best eSIM for Greece comes down to your trip length, data needs and budget. Ubigi is the pick for both short and long stays, with the cheapest unlimited data on this page: $24 for a week, $55 for a month, with uncapped tethering.
Saily has closed the gap on price this year, with 10 GB for a month at $18.69 using the code, and it’s the only one bundling security tools and lounge perks. Holafly is the one to take if you want unlimited data that never slows down, and it’s the only provider reaching all three Greek networks, which matters once you leave the mainland.
Airalo’s cheap unlimited data and uncapped sharing make it the group-travel pick, and Jetpac rounds things off with the lowest entry price and free data for the apps you’ll actually open.
Frequently Asked Questions
Can I buy an eSIM for Greece before my travel?
Yes, you can, and you should. The most convenient way to pick a reliable eSIM for Greece is to pick it while you're home. You can activate it manually when you arrive, but in most cases, it'll be automatically activated when you connect to a Greek WiFi network. To make it clear, you can also buy an eSIM while in Greece.
Is my phone compatible with an eSIM for Greece?
It depends on the phone. If you have a newer device, say after 2020, you can likely use it. For instance, the iPhone XS, released in 2018, supports eSIMs. On Samsung's side, the S20, which was released in 2020, is the oldest eSIM-compatible device. You can always check if your phone is compatible on an eSIM's site. If it isn't, consider a physical SIM card when you arrive in Greece. However, know that it isn't better or more convenient than an electronic SIM card.
Should I just rely on roaming data in Greece?
No, you shouldn't because roaming is very expensive and often unreliable. Roaming is when you use your domestic data, resulting in slower and inconsistent connections, while you keep paying an exorbitant price. Simply put, you pay a lot and get very little. With a trusted eSIM for Greece, it's the opposite.
Can I make calls and text with an eSIM in Greece?
Yes, you can, but your eSIM must support this function. You can always call and text with a VoIP app like Viber, Telegram, or WhatsApp. However, to send SMS and make voice calls, you must have a plan that allows it. Our top five aren't viable, but you can pick aloSIM if you're okay with its slower connection speed.
