If you need to run a laptop, a second phone, a tablet or a router off your eSIM across Europe, pick a plan that explicitly allows tethering and gives you enough data to make hotspotting worthwhile. On that count, Marco Polo Mobile eSIM is the straightforward answer for heavy users: tethering is allowed, allowances run up to 800GB, and cost-per-GB drops to roughly €0.09–0.14 at the top tiers — for example 320GB for €45 on a 28-day plan, or 800GB for €75 over 56 days. If you only need to share a little data on a short holiday, a budget tourist eSIM is fine. If you plan to “cut the cord” on home broadband while you travel, keep reading.
Why tethering is the detail that trips people up
Plenty of eSIMs work beautifully on your phone and quietly fall apart the moment you turn on the hotspot. Some providers block tethering outright. Others allow it technically but the “unlimited” plan you bought is throttled so hard after a fair-use cap that a laptop video call becomes unusable. The headline GB number means nothing if the terms say you can’t share it.
For truckers and nomads this matters more than for tourists, because tethering is usually the whole point: a cab laptop for e-CMR and route planning, a tablet for navigation, a work machine for video calls, maybe a travel router feeding several devices. You’re not sharing occasionally — you’re sharing all day.
Rule of thumb: for hotspotting, “tethering allowed” plus “large hard-GB allowance” beats “unlimited” every time. Unlimited plans are built for one phone, light use, and almost always come with fair-use throttling.
The comparison table
Marco Polo’s figures below are exact. Competitor cells are deliberately qualitative — their pricing and allowances shift, so check their current sites rather than trust a number pulled from memory.
| Provider | Data | Validity | Cost per GB | Tethering | Best for |
|---|---|---|---|---|---|
| Marco Polo Mobile | 25GB–800GB (e.g. 160GB €35, 320GB €45, 800GB €75) | 28 / 56 / 90 days | ~€0.09–0.14/GB at top tiers | Yes, allowed | Heavy tethering, long stays, Europe (37 countries) |
| Airalo | Small per-plan allowances; ~200 destinations | Varies — check site | Higher per GB — check site | Usually allowed, small data limits sharing | Widest country coverage; light use |
| Holafly | “Unlimited” (fair-use throttled) | Varies — check site | N/A (unlimited pricing) | Often restricted / disallowed | Light single-phone users who want simplicity |
| Saily / Nomad / Yesim | Modest tourist allowances | Short — check site | Varies — check site | Varies by plan — check site | Short trips with light data |
| Ubigi | Mid-range plans; router-friendly | Varies — check site | Varies — check site | Generally allowed | IoT / router users, moderate data |
Providers ranked for hotspot use
1. Marco Polo Mobile — best for heavy, sustained tethering
This is the plan built for people whose hotspot is always on. Tethering and Wi-Fi sharing are included in the terms, so you’re not gambling on whether the hotspot button works. The allowances are what make it useful for sharing: 25GB (€15), 80GB (€25), 160GB (€35), 320GB (€45), 400GB (€55) and 480GB (€65) on 28-day plans; 320GB (€55), 640GB (€65) and 800GB (€75) on 56-day plans. There’s also a 36-country line with 20GB (€19) up to 500GB (€95) over 90 days.
Pros: genuinely large hard-GB caps, low cost-per-GB, 37-country Europe coverage on the Orange (France) network, a French number plus some calls and SMS, instant e-mail delivery.
The catch: it’s Europe-focused (37 countries), not a global 200-destination product. If your routes leave Europe regularly, this isn’t your single solution.
2. Ubigi — solid for routers and moderate sharing
Ubigi has a good reputation for working in travel routers and IoT setups, and tethering is generally fine. Allowances and prices sit in the middle of the market.
Pros: router-friendly, reliable, broad coverage.
The catch: for truly heavy data months you’ll likely pay more per GB than a big Marco Polo tier — check their current pricing against the numbers above.
3. Airalo — best if you need many countries, not much data
Airalo’s strength is coverage breadth — around 200 destinations. Tethering is usually permitted, but the per-plan data tends to be modest, so sharing it across a laptop and tablet drains it fast.
Pros: go almost anywhere, one app.
The catch: small allowances and higher cost-per-GB make it awkward for sustained hotspot use. We go deeper in Marco Polo vs Airalo for Europe.
4. Holafly — simple unlimited, but weak for tethering
Holafly markets simplicity: one “unlimited” plan, no counting GB. For a single phone on a short trip that’s appealing. For hotspotting it’s the wrong tool — tethering is often restricted or disallowed, and the fair-use throttling that backs “unlimited” bites hard once you’re feeding a laptop all day.
Pros: no data anxiety for light single-device users.
The catch: not built for sharing. See Marco Polo vs Holafly for the unlimited-vs-real-big-data breakdown.
5. Saily / Nomad / Yesim — fine for a short trip, light sharing
These budget tourist-data brands do what they say: cheap, modest allowances for a week or two away. Some plans allow tethering, some don’t, so read each plan’s terms. For occasional sharing of a map or a few e-mails they’re adequate.
Pros: low entry price for short trips.
The catch: allowances run out quickly under a hotspot, and validity is short. Not a long-stay or heavy-tether answer.
Match the plan to how you actually work
Long-haul driver living off the hotspot
If your cab is your office and your home, the hotspot runs all day: route software, e-CMR, streaming at the overnight stop, a video call with dispatch, maybe a tablet for the family. Treat this like home broadband. A 320GB 28-day plan at €45, or 640GB over 56 days at €65, keeps a laptop, phone and tablet fed without rationing. Our big-data Europe plans comparison and truck-driver picks go into the maths.
Occasional driver / weekend routes
Home every few days, lighter sharing. The 25GB (€15) or 80GB (€25) 28-day plans cover navigation, messaging and some tethering without overbuying. If you also want to compare this against your carrier’s roaming add-on, read eSIM vs roaming for truckers.
Digital nomad working from a laptop
Your laptop is the main machine, often tethered from the phone or a travel router, with video calls that chew data. Plus long stays mean you want validity in weeks, not days. A 56-day plan — 320GB (€55) or 800GB (€75) — or the 90-day 500GB (€95) line fits a multi-month trip. More on this in best eSIM for digital nomads in Europe.
Short trip, occasional sharing
A week in two or three countries, sharing a map now and then? A budget tourist eSIM, or Marco Polo’s smaller 20–25GB tier, is plenty. No need for a 320GB plan.
How to pick — and the common mistakes
- Confirm tethering in the terms, not just the ad. “Unlimited” headlines rarely mention that sharing is throttled or blocked.
- Buy hard GB, not “unlimited,” for hotspotting. A known cap you can actually use beats an unlimited label you can’t share.
- Estimate your real tethered load. Video calls and streaming over a laptop burn far more than phone browsing. If you’d do it at home, plan for it on the road.
- Match validity to the trip. A 28-day cap on a 6-week trip means buying twice. Use the 56- or 90-day plans for long stays — see long-validity eSIMs compared.
- Check country coverage against your route. Marco Polo covers 37 European countries; if you cross into non-covered regions, plan a backup. Our multi-country routes guide covers this.
- Don’t pay premium per-GB prices for heavy use. At ~€0.09–0.14/GB on top tiers, big plans are dramatically cheaper per gig than small tourist bundles — the cost-per-GB ranking shows the gap.
Frequently Asked Questions
Does Marco Polo Mobile allow hotspot and tethering?
Yes. Tethering and Wi-Fi sharing are included in the plan terms, so you can feed a laptop, tablet, second phone or travel router from your eSIM. Combined with allowances up to 800GB, that makes it practical to use as your main connection on the road, not just a phone-only backup.
Why not just buy an “unlimited” plan and tether off that?
“Unlimited” plans are built around one phone and light use. Most carry fair-use throttling that slows you to near-unusable speeds after a cap, and several restrict or forbid tethering entirely. For a hotspot that runs all day, a large hard-GB plan where sharing is explicitly allowed is more reliable — you know exactly what you’re getting.
How much data does tethering actually use?
More than you’d expect. A laptop defaults to higher-resolution streaming and heavier background updates than a phone, and video calls can run 1–3GB per hour. If you’d happily use home broadband for the task, size your plan accordingly — this is why heavy tetherers reach for the 320GB and up tiers.
Can I use Marco Polo in a travel router?
The eSIM works in any device that accepts eSIM profiles, including many travel routers, and tethering is allowed under the terms. Check that your specific router model supports eSIM provisioning before buying. If your setup needs a physical SIM slot instead, that’s a hardware limitation on the router, not the plan.
The short version
For a hotspot you lean on daily across Europe, you want tethering permission plus big, usable data — and that’s exactly where Marco Polo fits: 37 countries, tethering included, 25GB to 800GB, validity up to 90 days, and roughly €0.09–0.14/GB at the top. Airalo still wins if you need 200 countries; Holafly suits a light single-phone traveller; the budget brands are fine for a short trip with little sharing. But if your laptop, tablet and second phone all live off your eSIM, the big-data route is the one that won’t let you down.
