The four eSIM providers most worth comparing for European travel in 2026 are Airalo, Holafly, Saily, and Nomad. We bought all four, used them across Spain, Portugal, Germany, and the Netherlands, and tracked actual data speeds, hotspot behavior, and how each handles cross-border roaming inside the Schengen Area.

The headline numbers
| Provider | 10 GB / 30 days (Europe regional) | Unlimited / 30 days | Hotspot allowed? |
|---|---|---|---|
| Airalo Eurolink | $31 | not offered | Yes |
| Holafly Europe | n/a (unlimited only) | $57 | Yes (limited) |
| Saily Europe | $24 | $48 | Yes |
| Nomad Europe | $28 | not offered | Yes |
Airalo Eurolink
The most established eSIM brand. The Eurolink plan covers 39 European countries and works seamlessly across borders. Speeds were consistently 4G/LTE in our tests, occasionally 5G in Lisbon and Berlin. App is the cleanest of the four. Customer support is responsive but template-driven.
- Best for: Reliable, predictable coverage across multiple European countries.
- Watch out: No unlimited tier. Topping up is straightforward but costs roughly the same per-GB as buying fresh.
Holafly Europe
Holafly’s pitch is unlimited data — no caps, no overages. In practice, “unlimited” means “throttled after a daily soft cap of 500 MB–1 GB depending on country.” We hit throttling on day 4 in Spain. Hotspot tethering is officially allowed but heavily limited.
- Best for: Heavy users who want one bill and don’t tether much.
- Watch out: The fine print on “unlimited.” Hotspot is technically allowed but rate-limited to ~500 KB/s after the soft cap.
Saily Europe
Newcomer (launched by NordVPN’s parent in 2024). Cheapest of the four. Coverage and speeds matched Airalo in our testing. The app is rough around the edges and customer support is slower than Airalo‘s, but the price difference is meaningful.
- Best for: Budget-conscious travelers; people willing to trade some app polish for ~25% lower cost.
- Watch out: Account recovery is more painful if you lose access to your original email; the company is newer and less battle-tested.
Nomad
Mid-tier on price, mid-tier on features. Solid speeds, fewer countries covered than Airalo, but the app is excellent and topping up is the smoothest experience of the four.
Our recommendation: Saily for budget travelers, Airalo for everyone else. Skip Holafly unless you genuinely need unlimited and don’t tether.
Things nobody tells you about eSIMs
- Most eSIMs are data-only. You cannot make traditional phone calls or receive SMS to a real number. Use WhatsApp, Signal, or VoIP.
- Two-factor authentication SMS will not arrive on an eSIM data plan. Set up app-based 2FA before you leave.
- iPhone 14+ in the US has no physical SIM tray. eSIMs are mandatory abroad. Older Androids and dual-SIM iPhones can still mix physical + eSIM.
- Activate the eSIM before you fly — some require Wi-Fi for setup. Don’t be the person trying to scan a QR code at customs.

Final practical advice
Plan your timing carefully — many of the costs and complexities described above can be reduced significantly with even basic advance preparation. Researching 2-3 months ahead of any major commitment, asking questions of people who have already been through the process, and giving yourself buffer time for the inevitable surprises will save you both money and stress.
