Holafly
eSIMUnlimited data eSIMs for long stays
Best for: Long single-country stays, remote workers on video calls all day, and anyone who wants zero data anxiety for the whole trip.
Overview
Holafly specializes in unlimited-data eSIMs available for almost any duration, from a few days up to 90 days. Ideal for heavy users, remote workers and travelers who don't want to worry about running out of data in 160+ destinations.
Holafly's entire catalogue is built around one promise: never think about gigabytes again. Instead of data buckets, you buy a duration — 5 to 90 days, selectable day by day — and the data is unlimited for that window. That pricing model shines on long single-country stays: a month of working remotely in Spain or Portugal with daily video calls costs a flat rate, with no anxiety about hitting a cap mid-call. Two caveats from the plan terms: hotspot tethering is supported on most destinations but a few limit sharing speed, and a fair-use policy applies — after very high consumption (typically hundreds of GB in a billing cycle) speeds may be reduced, so it is unlimited for travel use, not a home-broadband replacement. Installation is via QR from the web store or app, activation is automatic on first connection, and plans can be extended mid-trip from the app.
Note that Holafly's per-day cost is higher than capped plans from budget providers — the premium buys the removal of the data counter, not a cheaper gigabyte.
