Best eSIM for Digital Nomads in Europe
I lost a client because of Wi-Fi.
Sitting in a coworking space in Lisbon, mid-demo, my screen froze. The coworking Wi-Fi dropped. By the time I reconnected 90 seconds later, the client had left the call and sent a message saying "let's reschedule when your connection is stable."
We never rescheduled. They went with someone else.
That was 2024. Since then, I've never relied on a single internet connection for work. My laptop runs on coworking Wi-Fi or cafe internet. My phone runs on its own cellular data via eSIM. If one fails, I hotspot from the other. It's redundancy, and when your rent depends on being online, redundancy isn't optional.
Here's what I've learned about eSIM providers after cycling through three of them across Lisbon, Barcelona, Berlin, Split, and Athens.
What Digital Nomads Actually Need (vs Tourists)
Tourist eSIM guides focus on data volume and price. That matters for nomads too, but there are three things tourists don't think about:
1. Upload Speed
Most people only check download speed. But if you're on video calls, sharing your screen, or pushing code, upload speed matters equally. Some eSIM providers throttle uploads while keeping downloads fast. You'll look fine watching content but freeze during a Zoom presentation.
2. Reliability Over Speed
I'll take a consistent 15Mbps over a connection that spikes to 50Mbps but drops to zero every 8 minutes. Consistency matters more than peak speed for remote work.
3. A Real Phone Number
This is the one that catches nomads off guard. You need a phone number for:
- Verifying bank accounts and financial apps (Wise, Revolut)
- Calling landlords and property managers
- Registering for local services (gym, coworking memberships)
- Two-factor authentication that requires SMS
Data-only eSIMs don't give you a number. You're stuck using VoIP or hoping WhatsApp works. It usually does. Until it doesn't, and you're locked out of your Wise account in a foreign country.
The Providers (Tested Personally)
GOAN
This is what I currently use. 20GB for $29 on the group plan (my girlfriend Linh and I are both on it). Real phone number included. Works across all of Europe plus Asia, which matters because I bounce between Vietnam and Europe.
What I like: Consistent speeds across countries. The phone number. No app to install. Just scan the QR code and go.
Real speeds I got:
- Lisbon: 28Mbps down / 12Mbps up
- Barcelona: 35Mbps down / 15Mbps up
- Berlin: 22Mbps down / 8Mbps up
- Split: 18Mbps down / 7Mbps up
These are mobile speeds, not fibre. They're more than enough for video calls, screen sharing, and general work. I hotspot my laptop from my phone regularly when coworking Wi-Fi is sketchy.
Airalo
Used this for my first 6 months of nomading. Solid provider, big marketplace. But the plans are almost all data-only (no phone number) and country-specific.
That country-specific thing is the killer. I was in Barcelona, took a weekend trip to Andorra (because why not), and my Spanish eSIM died at the border. Had to buy an Andorra plan for one weekend. Then another plan when I moved to Portugal.
Per-GB cost is also higher than GOAN: about $2.60/GB vs $1.45/GB.
Holafly
Tried their "unlimited" Europe plan for two weeks. The first few days were great. Then the throttling kicked in. After about 1.5GB per day, speeds dropped to basically unusable levels. Fine for checking email. Not fine for a client video call.
For $44 over 15 days, I expected better. Went back to GOAN.
My Backup System
Here's my full connectivity stack:
Primary (work laptop): Coworking Wi-Fi or cafe internet Backup (phone): GOAN eSIM, always on, ready to hotspot Emergency: Tethering from Linh's phone (also GOAN)
If the coworking drops, I switch to phone hotspot in under 10 seconds. Client doesn't even notice. I've done this mid-call at least a dozen times.
The key is having the backup ready before you need it. Not "I'll buy an eSIM if the Wi-Fi fails." By then you've already lost the call.
European Cities Ranked for Nomads (Connectivity Edition)
Based on my experience across 14 months in Europe:
Tier 1 (Excellent connectivity)
Lisbon: Fast mobile data, tons of coworking spaces, reliable cafe Wi-Fi. The nomad hub of Europe for a reason. My GOAN eSIM consistently hit 25-35Mbps.
Berlin: Germany's mobile infrastructure is surprisingly good in cities (terrible in rural areas). Lots of tech-focused coworking spaces with enterprise-grade Wi-Fi.
Tallinn: Estonia is a digital-first country. Free city Wi-Fi, fast mobile data, and the e-Residency program makes it nomad-friendly at every level.
Tier 2 (Good, with caveats)
Barcelona: Great mobile speeds. But many cafes have started limiting Wi-Fi to customers who buy something every hour. Having your own data means you're not dependent on cafe goodwill.
Athens: Better than expected. Good 4G coverage, affordable coworking. The old city has some dead spots but nothing unworkable.
Split: Solid in the city, patchy on the islands. If you're working from Hvar, bring your own connection.
Tier 3 (Workable but plan ahead)
Lisbon suburbs/Algarve: Coverage drops outside the city. If you're planning a coastal retreat, test your connection before committing to a month's rent.
Rural anywhere: European countryside mobile coverage varies wildly. Always have your eSIM as backup when you're outside major cities.
The Visa Run Factor
If you're a non-EU nomad in Europe, you're probably dealing with the Schengen 90/180 rule. That means visa runs to non-Schengen countries (UK, Albania, Montenegro, Turkey) or rotating between EU and non-EU countries.
Every visa run means crossing a border. Every border crossing means your country-specific SIM or eSIM might stop working.
I've done visa runs from:
- Portugal to UK (Schengen reset)
- Croatia to Montenegro (pre-Croatia-joining-Schengen)
- Greece to Turkey (weekend trip + Schengen reset)
GOAN's plan covers 105+ countries. Turkey, UK, Montenegro, Albania, all included. My data worked at every border crossing without me doing anything. No new plan, no settings change, no moment of panic when Google Maps dies in a foreign bus station.
If you're planning visa runs, read my detailed breakdown of how eSIMs handle border crossings.
Cost Analysis (Monthly)
Here's what connectivity costs me as a nomad:
| Item | Monthly Cost |
|---|---|
| GOAN eSIM (20GB) | $29 |
| Coworking membership | $100-200 |
| Cafe spending (for Wi-Fi access) | $50-80 |
| Total connectivity | $179-309 |
That might seem like a lot. But my remote job pays a US salary. A single dropped client call costs more than a year of eSIM data. The $29/month for a reliable backup connection is the cheapest insurance I have.
Compare that to the "save money by using free Wi-Fi only" approach: slower, unreliable, requires you to sit in specific locations, and leaves you exposed on public networks. I ran the numbers in my full nomad cost breakdown and connectivity is the one line item you should never cut.
Setting Up for Nomad Life
If you're about to start nomading in Europe:
- Get your eSIM set up before you leave home
- Download offline maps for your first city
- Test your phone hotspot speed (Settings > Personal Hotspot)
- Set up a VPN for public Wi-Fi (I use Mullvad)
- Keep your home SIM active for bank verifications (Dual SIM)
Your career depends on your connection. Don't leave it to chance.
