The verdict

The biggest, the broadest and the one to buy when you are going somewhere the others have barely heard of: over two hundred places, and a global plan covering a hundred and sixty-eight. It is also the only one here that can replace a phone line rather than just feed it, because its American plan includes real minutes and texts and its global plan comes with a proper US number. You pay for that reach. It is the dearest of the three directly comparable plans on this page, and its review record is the weakest of the five, largely over refunds refused once a sliver of data has registered.

Airalo is the default, and for once the default is defensible. Thirty million people have used it, it sells in more than two hundred places, and if you are heading somewhere the smaller sellers have skipped it is usually the one that has it. It…

The verdict

The cheapest of the three comparable plans, and the only one selling a proper subscription: three dollars a month keeps a gigabyte of European data and a permanent eSIM sitting dormant in your phone between trips. That suits anyone who crosses Europe several times a year more than any one-off plan does. It names the networks it runs on, which the others mostly do not. The catch is in the reviews, where the same story repeats too often to ignore: it works for the first few days and then quietly stops, sometimes while still showing as connected.

Nomad undercuts both Airalo and Saily on the two plans this page compares, and it is more open than either about whose network you are actually on — EE, Orange, Vodafone, O2 and Telia across Europe, the big three in America. The genuinely different product…

The verdict

The one built for staying rather than visiting. Ubigi sells by the year as well as by the trip: a hundred gigabytes to draw down over twelve months for a hundred and ninety dollars, or five gigabytes a month for a year at forty-nine. Sharing is allowed on every plan including unlimited, which runs sixty gigabytes at full speed before it slows — far and away the most generous ceiling here. It is a real operator with its own network code rather than a reseller, and Apple lists it. But it sends no texts and issues no number at all, which breaks any login that verifies by SMS.

Ubigi is the odd one out here, and it is on this page precisely because of that. The other four are built around a tourist buying a fortnight of data. Ubigi will sell you a year. Two shapes are worth knowing apart. The annual regional…

The verdict

The most heavily advertised eSIM and the one we would steer most of this audience away from. Sharing to a laptop is capped at a gigabyte a day, which defeats the purpose for anyone working off it, and the point at which the unlimited data slows down is not published at all. At nearly seventy-four dollars for a month in Europe you are paying roughly four times Saily or Nomad, which only pays off if you genuinely burn through twenty gigabytes or more on the handset itself. Top-ups no longer exist, so a longer trip means buying and juggling a second eSIM.

Holafly is included because you will see it everywhere and deserve a straight answer about it. It sells days, not gigabytes. A month across thirty-three European countries is $73.90, the same as a month in the USA alone, with no limit on how much you…
