Holafly vs Saily eSIM (2026)
These are not the same kind of “unlimited” plan. Official Holafly Europe prices on November 10, 2026 ran from $11.90 for 3 days to $76.50 for 30 days, with a 6-month refund window, Always On 1 GB backup, 1 GB of hotspot data per day, and 33 destinations. Official Saily Europe pages listed a 15-day unlimited plan at $49.99, 35 countries, a written 5 GB-per-day then 1 Mbps fair-use rule, and unlimited hotspot sharing. We compared those written terms, not a speed test.
ComparisonAiralo vs Saily eSIM (2026)
On official pages fetched November 10, 2026, Airalo’s 7-day Europe unlimited plan listed at $27, with a written 3 GB-per-day then 1 Mbps fair-use rule and 41 countries. Saily’s Europe page listed a 1 GB / 7-day fixed plan at $4.99 and a 15-day unlimited plan at $49.99, covering 35 countries. Saily’s unlimited-data FAQ says regional unlimited plans get 5 GB of high-speed data per 24 hours, then 1 Mbps — a higher daily allowance than Airalo’s default 3 GB, if that FAQ figure is the one on the plan you buy.
ComparisonAiralo vs Nomad eSIM (2026)
Airalo’s official 7-day Europe unlimited plan listed at $27 on November 10, 2026, for 41 countries, with a written 3 GB-per-day then 1 Mbps fair-use rule. Nomad’s official Europe page listed fixed-data plans, including 1 GB / 7 days at $7 and 20 GB / 30 days at $29, on a table shown with a 36-destination label that includes Turkey. Nomad supports tethering on most plans and offers a 30-day refund window for unused, unactivated plans — and lists unlimited plans as non-refundable.
ComparisonAiralo vs Holafly eSIM (2026)
For a 7-day Europe trip, official list prices were almost the same on November 10, 2026: Airalo $27, Holafly $27.50. The useful split is policy, not a dollar or two. Airalo’s written fair-use rule is 3 GB of high-speed data per 24 hours, then 1 Mbps, with no tethering cap in that policy. Holafly’s Europe plan lists 1 GB of hotspot data per day, a 6-month refund window, and operator fair-use slowdowns generally lasting no more than one day.
Explainers
What “Unlimited” eSIM Plans Actually Allow (2026)
“Unlimited” on a travel eSIM is usually a daily high-speed allowance, then a slower speed, not uncapped 5G. Official Airalo policy is 3 GB per 24 hours, then 1 Mbps, resetting from the time you activated the eSIM. Official Saily policy is 5 GB of high-speed data per 24 hours, then about 1 Mbps. Official Holafly language describes operator fair-use slowdowns, generally lasting no more than one day, without a daily gigabyte figure. Read the live plan details before you buy. This is not a speed test.
