Airalo vs Holafly vs Saily
Three of the most searched travel eSIM brands. Airalo and Saily sell fixed gigabytes (plus some unlimited). Holafly sells days of unlimited phone data. The “best” one depends on whether you watch a data counter or a hotspot cap.
Head-to-head
| Provider | Plan model | Example 10 GB | Unlimited angle | Hotspot | Best for |
|---|---|---|---|---|---|
| Airalo | Fixed GB + some unlimited | Varies (e.g. Japan ~US$18, USA ~US$22.50) | ~3–5 GB/day then throttle | Shares plan data; no separate prepaid cap reported | Widest destination list; flexible top-ups |
| Holafly | Unlimited by days only | N/A — no fixed GB | Phone FUP often unpublished | ~500 MB–1 GB/day on prepaid | Heavy phone streaming / calls |
| Saily Value lean | Fixed GB + unlimited tiers | Often matches or undercuts Airalo | ~5 GB/day then ~1 Mbps (many regions) | Generally unrestricted on fixed plans | Price + Nord Security app extras |
Who wins when?
Airalo if you need an obscure destination or like the marketplace experience. Saily if the same destination is cheaper (or similar) and you want hotspot without a separate daily tether cap. Holafly if you’ll burn phone data hard and barely tether — or you’ve checked a subscription tier that includes hotspot.
For pure cheap 10 GB on popular routes, also open the destination pages — Ubigi and Nomad frequently beat all three.
FAQ
Is a travel eSIM cheaper than roaming?
Usually yes — a 10 GB travel eSIM typically costs a fraction of daily roaming passes from home carriers. Heavy users should still compare per-GB prices.
When should I install my travel eSIM?
Install it at home on Wi-Fi a day or two before you fly, but keep it switched off until you land, because many plans start their validity on first connection.
Is 'unlimited' eSIM data really unlimited?
Rarely. Most unlimited plans slow you down after a daily fair-use cap (often 1–5 GB/day) and limit hotspot use. Check the cap before you buy.
