Holafly: The Unlimited Data Specialist
Holafly was one of the first eSIM providers to go all-in on unlimited data plans — a smart bet that paid off as travelers increasingly expect unlimited connectivity without watching a data counter. Plans are priced per time period (5 days, 10 days, 30 days), not per gigabyte.
The unlimited proposition is especially appealing for Europe trips, where Holafly has built strong coverage and competitive pricing. For a 10-day Europe trip, Holafly at ~$29 unlimited is genuinely hard to beat if you're a heavy user.
The fair use policy is worth noting: Holafly's unlimited has a soft throttle for genuinely extreme usage (torrenting, 4K streaming for hours). For normal travel use, you won't notice it.
Saily: Clean Pricing, Solid Coverage
Saily (owned by Finnish cybersecurity company F-Secure) entered the eSIM market with a simple value proposition: clean tiered pricing, reliable service, and a polished app. They offer fixed GB plans across 130+ destinations at competitive prices.
Saily's tiered pricing is refreshingly transparent — you know exactly what you're getting. Their 5 GB and 10 GB plans for Asia and Europe are priced very competitively, often undercutting Holafly significantly for longer stays.
Price Battle: 2-Week Europe Trip
| Provider | Plan | Price | Notes |
|---|---|---|---|
| Holafly | 15 days unlimited | ~$39 | No data cap |
| Saily | 10 GB / 30 days | ~$22 | Should cover 2 weeks |
| Holafly | 10 days unlimited | ~$29 | If trip is exactly 10 days |
| Saily | 5 GB / 30 days | ~$15 | Light user only |
Which One Should You Buy?
Choose Holafly if: you hate data anxiety, plan to stream video or video call frequently, or your trip is under 2 weeks where the unlimited premium isn't too painful.
Choose Saily if: you're a moderate data user, your trip is 2+ weeks (fixed GB plans get better value long-term), or you want the lowest possible price for your trip.
