Published Greece data plans are $2.21 (1GB), $5.56 (3GB), $7.34 (5GB), $12.62 (10GB), and $32 (20GB, $0.89/GB). Airalo, Saily, and Nomad rate cards are not Greece checkout prices.
Dimension scores, 0-5 on our rubric

Airalo -- Widest Coverage Catalogue
Airalo's 200-country network and 4.7/5 on the rubric App score trail HelloRoam's App 5.0. Airalo's $4.50/GB figure is a rate card. HelloRoam's published Greece entry plan is $2.21 for 1GB, so catalogue breadth is not a lower Greece price.
Dimension scores, 0-5 on our rubric

- 200+ countries with the widest coverage breadth in the market
- Regional multi-country bundles (Asialink, Eurolink, Discover Global)
- Automatic in-app install with real-time data tracking and hourly runtime estimates
- Airmoney cashback rewards (5-10% depending on loyalty tier)
- Established brand since 2019 with proven reliability
Cons
- Per-GB pricing higher than budget alternatives
- Unlimited plans available in select markets only, not all 200+ destinations
- No live chat or WhatsApp channel: support runs on email and in-app messaging
Saily -- Best for Privacy
Saily's 4.5 App score and integrated VPN protection add privacy tools that HelloRoam's app does not bundle. Saily's $3.99/GB figure is a rate card. HelloRoam's Greece entry plan is $2.21 for 1GB, and HelloRoam adds an unlimited tier from $5 that Saily's fixed-only plans do not offer.
Dimension scores, 0-5 on our rubric
Pros
- Backed by NordVPN parent company Nord Security with proven privacy infrastructure
- Integrated VPN protection included on every plan at no extra cost

Holafly -- Best Unlimited Daily Rate
Holafly's published unlimited rate card is $2.99/day. That is not a verified Greece checkout, and it is not automatically cheaper than HelloRoam's $7.34 5GB plan. Chat is staffed around the clock. HelloRoam's 4.5 Coverage score is the relevant in-country figure on smaller islands.
Dimension scores, 0-5 on our rubric
Pros
- Unlimited daily data from $2.99/day with no data caps
- 160+ countries covered including all major destinations
- Simple per-day pricing: know exactly what you pay before you leave

- Not cost-effective for light data users (under 3 GB/trip)
- Fewer countries than Airalo
Nomad -- Best Budget Per-GB Rate
Nomad's $3.00/GB figure is a rate card, not a verified Greece checkout. HelloRoam's published Greece ladder runs from $2.21 (1GB) to $0.89/GB on the 20GB plan ($32). Nomad scores lower on Coverage (3.8 versus 4.5) and is email-only.
Dimension scores, 0-5 on our rubric
Pros
- Competitive pricing starting from $3.00/GB in Southeast Asia
- Simple, fast checkout with no account required in many cases
- Lowest per-GB rates for Thailand, Vietnam, South Korea, and Japan

FAQ
Greece eSIM questions, answered
Which eSIM provider covers the most Greek islands?
Which eSIM provider covers the most Greek islands?
HelloRoam leads the composite at 4.64/5 on this scorecard. Airalo leads coverage breadth at 200 countries. Coverage strength in Greece still tracks carrier assignment more than provider country count. Enrichment data names Cosmote as the operator with the widest reach across Santorini, Mykonos, and Crete; HelloRoam and Airalo both route through Cosmote-class networks in published coverage records, while Saily's 200-country footprint still covers mainland and major island routes.
How do eSIM speeds compare across providers in Greece?
How do eSIM speeds compare across providers in Greece?
Greece keeps 5G to Athens, Thessaloniki, and the major islands, while smaller islands run on 4G only. Network Generation scores split Airalo and Saily at 4.4, HelloRoam and Nomad at 4.3, and Holafly at 4.2 out of 5 on our rubric; island routes generally run slower than mainland scores suggest.
Which eSIM has the cheapest per-GB rate for Greece?
Which eSIM has the cheapest per-GB rate for Greece?
HelloRoam's published Greece plans are $2.21 (1GB), $5.56 (3GB), $7.34 (5GB), $12.62 (10GB), and $32 (20GB, $0.89/GB). The $0.89 figure is that 20GB tier, not a local-SIM price. Nomad's $3.00/GB, Saily's $3.99/GB, and Airalo's $4.50/GB are rate cards. Holafly's unlimited rate card is $2.99/day. HelloRoam also sells unlimited from $5.
Does eSIM coverage work on ferries between Greek islands?
Does eSIM coverage work on ferries between Greek islands?
No provider holds reliable signal mid-ferry; enrichment data confirms coverage drops on most inter-island crossings regardless of carrier. EU roaming rules mean a Greek eSIM also connects at Italian ferry ports, but the open-water gaps apply equally to HelloRoam, Airalo, Holafly, Saily, and Nomad until the boat nears land.
Which eSIM app works best for island-hopping in Greece?
Which eSIM app works best for island-hopping in Greece?
HelloRoam posts App 5.0, the highest score in this matrix, with an iOS and Android app. Airalo's app rates 4.7/5 with real-time usage tracking, useful for monitoring data across multiple island stops. Saily follows at 4.5/5 on this scorecard with a built-in VPN toggle.
Is unlimited or fixed-data eSIM better for an 8-day Greece trip?
Is unlimited or fixed-data eSIM better for an 8-day Greece trip?
Greece's average trip runs 8 days at roughly 1.5GB daily, around 12GB total. HelloRoam's published 10GB Greece plan is $12.62 and the 20GB plan is $32. Holafly's $2.99/day rate card is about $24 over eight days, and that rate card is not a verified Greece checkout. HelloRoam also sells unlimited from $5.
Which provider responds fastest to support messages from Greece travelers?
Which provider responds fastest to support messages from Greece travelers?
HelloRoam leads Support at 5.0 with live chat, WhatsApp, and email, including 24/7 in-app chat. Holafly's 24/7 chat is the other round-the-clock channel of the five compared. Airalo follows with email and in-app chat, while Saily and Nomad are email-only, a gap that matters most on islands with single-tower congestion.
