Best eSIM for 30 days in Europe is about choosing a data plan that won’t leave you offline halfway through your trip. Maps running 8 hours a day, translating menus in four languages, uploading stories from Santorini, video calling home from a train between Paris and Amsterdam — and that’s just week one. A 10GB plan won’t survive two weeks, let alone thirty days across multiple countries.
For an eSIM Europe long stay of 30 days, you need either unlimited data or a data bucket big enough that you never check your balance. The options look similar on the surface — but the wrong pick costs you $50+ more than necessary, or leaves you throttled on day 15.
The three best eSIMs for 30 days in Europe:
- Holafly: ~$75 for 30 days unlimited (Europe plan) or $64.90/mo unlimited global (Plans subscription)
- Maya Mobile: ~$55/30 days unlimited (3GB/day high-speed, then reduced)
- Nomad: $29/50GB/30 days — best metered option if you don’t need truly unlimited
Why trust this guide? I’m based in Portugal, I’ve personally used Holafly and Nomad in Europe, and I compare eSIM providers for European travelers full-time. Every price and data cap in this guide is verified weekly against official sources and cross-checked with thousands of real traveler reviews.
Watching your budget? Nomad 50GB for $29 covers a full month for most travelers.

Reading the table: If you want a 1-month Europe data plan without limits, Holafly is the safest pick — no daily cap, ~90GB ceiling. If you want unlimited but cheaper, Maya at ~$55 is the best value with a usable 3GB/day allowance. If you don’t actually need unlimited, Nomad’s 50GB for $29 is the Europe 30-day SIM alternative that most travelers should seriously consider before paying double for “unlimited” they won’t use.
Holafly vs Maya for 30 Days: Which Unlimited Is Better?
This is the real decision for most month-long travelers. Both offer unlimited data for 30 days, but the details change everything.
| Feature | Holafly (~$75/30d) | Maya Mobile (~$55/30d) |
|---|---|---|
| How data works | Use as much as you want per day | 3GB/day fast, then slower |
| Monthly total (fast) | ~90GB before any slowdown | ~90GB (3GB × 30 days) |
| After heavy use | Slowed for 24h, then resets | Slowed until next day |
| Hotspot | Limited (500MB-1GB/day) | Full hotspot included |
| Auto-renew | ❌ Buy new plan each month | ✅ Same price, up to 180 days |
| Countries | 33 | 30+ |
| Price | ~$75 | ~$55 |
The verdict on Holafly vs Maya: Holafly lets you use data however you want — 5GB one day, 500MB the next — without daily throttling. Maya locks you at 3GB/day, but saves you $20. Both deliver roughly ~90GB of high-speed data per month. If unpredictable usage stresses you out, Holafly. If you’re consistent and budget-conscious, Maya. If you’re staying longer than 30 days, Maya’s auto-renew at the same price for up to 180 days is a serious advantage — Holafly makes you buy a new plan each month.

Budget Options: Big Data Without Unlimited
Not everyone needs unlimited. If you’re disciplined with data or connect to hotel Wi-Fi regularly, a large metered plan saves serious money.
Nomad 50GB / $29 / 30 days — The standout value. At $0.58/GB, nothing comes close. 50GB means you can use ~1.7GB/day for a full month without thinking about it. That covers Maps, messaging, social media, video calls, and moderate photo uploads. You only run short if you’re streaming video daily or hotspotting to a laptop.
SimOptions 30GB + calls / $29 / 30 days — Same price as Nomad but with 20GB less data. The trade-off? You get a European phone number — the only eSIM option that includes one. If you need to make local calls for restaurant reservations, apartment check-ins, or business contacts across Europe, SimOptions is unmatched.
Airalo 50GB / $72 / 30 days — Same data as Nomad at more than double the price. Hard to recommend for 30-day stays unless you specifically prefer Airalo’s app experience and 42-country coverage.
Tips for a 30-Day European Trip
Buy your eSIM before day one. Install on Wi-Fi at home. When you land at your first European airport — Schiphol, CDG, Fiumicino, wherever — your data is already active. Thanks to EU roaming regulations, one eSIM plan works seamlessly across all member states. A month-long trip has enough logistics without adding “find a SIM shop” to day one.
Track your data in the first week. Most provider apps show real-time usage. If you’ve burned 14GB by day 7, you’re on pace for ~60GB/month and need unlimited. If you’ve used 8GB, a 50GB metered plan handles the whole month — and the Europe 30-day SIM alternative from Nomad at $29 saves you $45+ over unlimited.
Use hotel Wi-Fi for heavy tasks. Downloading Netflix episodes, syncing cloud storage, and video conferences drain data fast. Save your eSIM data for when you’re moving — transit, walking tours, restaurant hunting.
Consider Holafly Plans for multi-month stays. If your trip extends beyond 30 days, Holafly’s subscription at $64.90/mo (unlimited global, unlimited hotspot) is cheaper than buying two 30-day Europe plans (~$150). And you can cancel after any month.
Hotspot matters for digital nomads. Holafly destination plans cap hotspot at 500MB-1GB/day. Maya includes full hotspot. Nomad includes full hotspot. If you need to tether a laptop, this changes the calculus — see my Digital Nomads eSIM guide for the breakdown.
FAQ
What is the best eSIM for 30 days in Europe?
The best eSIM for 30 days in Europe depends on whether you need unlimited or 50GB. For unlimited data, Holafly at ~$75/30 days offers the highest ceiling (~90GB before throttling). Maya Mobile at ~$55 is cheaper with a 3GB/day cap. For metered data, Nomad’s 50GB at $29 is the best value — enough for most travelers using 1.5-2GB/day.
How much data do I need for 30 days in Europe?
Most travelers use 1.5-2GB per day. A 30-day trip needs 45-60GB for moderate use. Light users (Maps, messaging only) can manage with 30GB. Heavy users (streaming, remote work, video calls) need unlimited. See my How Much Data guide.
Is Holafly worth it for a full month?
At ~$75 for 30 days unlimited, Holafly costs more than Maya (~$55) or Nomad (50GB/$29). But Holafly has no daily cap — you can use 5GB one day and 1GB the next without throttling. For travelers who want zero data anxiety across a month-long European trip, the premium is worth it.
Can I use the same eSIM for 60 or 90 days in Europe?
Maya Mobile auto-renews up to 180 days at the same price (~$55/month). Holafly Plans ($64.90/mo) renews monthly until you cancel. Nomad requires buying a new plan after 30 days. For extended stays, Maya or Holafly Plans offer the smoothest experience.
Does eSIM hotspot work for a full month?
Depends on the provider. Nomad and Maya include full hotspot. Breezy includes hotspot. Holafly destination plans cap hotspot at 500MB-1GB/day — the global plan ($64.90/mo) includes unlimited tethering. If hotspot matters for your laptop, check before buying.
What’s the cheapest eSIM for 30 days in Europe?
Nomad at $29/50GB. Nothing matches this price-to-data ratio for a full month. Breezy’s unlimited at ~$48 is the cheapest unlimited option but caps high-speed at 1GB/day. The sweet spot is Maya at ~$55 for unlimited with a usable 3GB/day high-speed allowance.
Best eSIM for 30 Days in Europe: Final Verdict
A month in Europe is long enough that the wrong data plan costs you real money — or worse, leaves you offline on day 12 in a city where you don’t speak the language.
For 80% of travelers, the answer is Holafly at ~$75 for 30 days unlimited. No daily cap, no counting megabytes, no running out. You pay once, your data works across 33 European countries for a full month, and you never think about it again. That peace of mind is worth the extra $20 over Maya.
If you’re on a tight budget and 50GB is enough, Nomad at $29 is the smartest money move in this entire guide. Most travelers don’t need unlimited — they think they do.
