If you genuinely need 100GB or more<\/strong> on a European eSIM \u2014 not a theoretical “unlimited” plan that gets throttled, but a real, usable allowance you can tether to a laptop or dashcam \u2014 the shortlist is short. Marco Polo Mobile<\/strong> is the clearest pick here: it sells plans from 25GB up to 800GB<\/strong>, with 100GB at \u20ac39, 160GB at \u20ac35 (28 days), and 320GB at \u20ac45, all with tethering allowed and 37-country Europe coverage. Most mainstream travel eSIMs simply don’t offer plans that big; the ones that advertise “unlimited” usually cap or slow you after a fair-use threshold. Below is an honest breakdown of who actually serves heavy-data users in Europe, and who’s better left for short trips.<\/p>\n

What “large data” really means for Europe<\/h2>\n

There’s a gap between tourist eSIMs and work eSIMs. A tourist on a 10-day city break burns maybe 5\u201315GB \u2014 maps, messaging, some streaming. A long-haul driver, a digital nomad working remotely, or anyone running a hotspot for multiple devices can clear 100\u2013300GB in a month without trying. Video calls, cloud backups, software updates, Netflix in the cab, a tablet and a phone tethered off one plan \u2014 it adds up fast.<\/p>\n

So the real question isn’t “who has an eSIM for Europe” \u2014 almost everyone does. It’s “who sells a single plan with 100GB+<\/strong> at a sane price, on long validity, with tethering permitted.” That filters the market down quickly.<\/p>\n

Marco Polo’s actual large-data plans<\/h2>\n

These are the real numbers \u2014 use them to work out what fits your month. Marco Polo’s eSIM Euro<\/strong> runs on the Orange (France) network across 37 European countries, includes tethering\/Wi-Fi sharing, and comes with a French number plus some calls and SMS. Delivery is by e-mail.<\/p>\n
