Introduction
There is a specific moment most expats in Barcelona will recognize: you’re trying to open a bank account, register for something official, or sign up for a service, and the form asks for a Spanish phone number. Not your home country number. Not a virtual number. A Spanish number, one that proves you’re actually here.
Getting a local number is one of the quiet milestones of building a life in Barcelona. It’s what gets you into WhatsApp groups, what Spanish contacts will actually message, what banks, landlords, and half the apps on your phone expect when they send a verification code. And yet it’s one of those things that somehow always seems to get deprioritized in the chaos of everything else.
An eSIM with a Spanish number included is the fastest, cheapest way to solve this problem, no phone shop visit, no contract, no paperwork (in a language you’re still learning). And the eSIM market is crowded enough that figuring out which provider is actually worth it takes longer than it should.
We’ve done that research. Here’s what you need to know, and why Holiday eSIM is the provider we recommend to the Penya community.
What Is an eSIM?
An eSIM (embedded SIM) is a digital SIM card built directly into your phone. Instead of inserting a physical plastic card, you scan a QR code and your mobile plan activates instantly, no store visit, no waiting for mail, no fumbling with a SIM tray pin.
Most smartphones made in the last four years support eSIM, including recent iPhone, Samsung Galaxy, and Google Pixel models. If you’re unsure, check your phone’s settings under “Mobile/Cellular Data” for an option to add an eSIM, or look up your model online.
The biggest practical advantage: your phone can run two numbers simultaneously, your regular Spanish or home-country SIM for calls and verification codes, and an eSIM for data wherever you are.
Getting a Spanish Number as an Expat: Why It Matters More Than You Think
A Spanish phone number is one of the most practical milestones of expat life in Barcelona, and one of the easiest to overlook until you need one.
Here’s where it shows up: your bank requires a Spanish number to send 2FA codes. Your landlord texts it, not WhatsApp. Spanish government portals, Correos, health center registration, Glovo, Wallapop, nearly every local service defaults to a Spanish number for verification and contact. And socially, being added to neighborhood WhatsApp groups, local expat networks, or anything organized by Spanish contacts becomes far smoother when you’re not the one person with a foreign number.
It’s a small thing that compounds quickly. The longer you’re without one, the more friction it creates in daily life.
The traditional solution would be going to a phone shop, navigating a contract or prepaid plan in Spanish, waiting for a physical SIM. That works, but it’s exactly the kind of errand that gets pushed back repeatedly. An eSIM that includes a Spanish number activates in minutes from your phone, with no store visit and no paperwork.
This is one of the reasons we recommend Holiday eSIM specifically: their European plans include a real local phone number and calls, not just data, something neither Holafly nor Airalo offers on their standard plans.
Why Expats in Barcelona Use eSIMs
For expats, eSIMs solve a specific problem: staying connected across multiple countries without paying roaming fees or buying a new SIM at every border.
If you live in Barcelona but regularly travel within Europe, visit family abroad, or take work trips, managing connectivity is an ongoing cost and hassle. An eSIM with regional or global coverage handles it cleanly, buy once, activate instantly, stay connected from Barcelona to Berlin to New York.
Beyond travel, there’s a more day-to-day use case: having a reliable data backup. Your Spanish plan may have gaps. An eSIM on a separate network gives you a fallback and when you’re using an app like Penya to navigate the city and act on recommendations in real time, consistent data matters.
The Key Benefits
No roaming bills. Buy a local or regional data plan in advance. No surprise charges when you land.
Instant activation. Scan your QR code and you’re connected. Setup takes a few minutes, and you can do it before you leave home.
Keep your home number active. Because your eSIM runs alongside your regular SIM (dual SIM), you keep your primary number for calls, texts, and 2FA codes while using the eSIM for data.
No physical SIM to lose. Nothing to misplace, bend, or drop. It lives on your device.
Multi-country coverage. One plan, dozens of countries. Ideal if your travel isn’t limited to a single destination.
How the Major eSIM Providers Compare
Holiday eSIM offers more value than Holafly, Airalo, or Saily for most expat use cases in Barcelona, particularly for European travel. Here’s the honest breakdown:
| Holiday eSIM | Holafly | Airalo | Saily | Popcorn | |
|---|---|---|---|---|---|
| Monthly price | From €47.93 | From ~€68 | From ~€45 | From ~€27 | $69 |
| Data (30 days) | 100GB | Unlimited* | 20GB | Unlimited* | Unlimited |
| Local Spanish number | ✅ Included in select plans | ❌ | ❌ | ❌ | ❌ |
| Keeps US number | ➕ Via dual SIM | ➕ Via dual SIM | ➕ Via dual SIM | ➕ Via dual SIM + add-on | ✅ Primary number |
| Hotspot / tethering | ✅ Unlimited | ⚠️ 500MB/day cap | ✅ | ✅ | ✅ |
| Countries (Europe) | 52 | ~35 | 42 | ~40 | Works globally |
| Money-back guarantee | ✅ 30 days | ❌ | ❌ | ❌ | ❌ |
| Customer rating (2026) | ⭐ 4.8/5 (Google) | ⭐ 4.6 (Trustpilot) | ⭐ 4.0 (Trustpilot) | ⭐ 4.5 (Trustpilot) | N/A |
*”Unlimited” plans from Holafly and Saily are subject to fair use policies, independent testing shows speeds can drop significantly after 4–5GB of heavy use.
A few things worth noting:
Holafly’s “unlimited” has real limitations. Independent testing shows speeds can drop significantly after around 4–5GB of use, and tethering (using your phone as a hotspot for your laptop) is capped at 500MB per day. If you work remotely or use your phone as a hotspot regularly, this matters.
Airalo is flexible but data-only. No calls, no local number included on most plans. Good for light travelers; less ideal for expats who need a full connectivity solution.
Saily (by NordVPN) is aggressively priced and has recently launched a US phone number add-on for $0.99/month, useful for Americans abroad who need to maintain a US number for banking, Venmo, or 2FA. But plans are lighter on data and coverage.
Popcorn is built for a different goal entirely. At $69/month, it’s the most expensive option here, and its pitch is essentially the opposite of what most expats in Barcelona actually need: it keeps your US number as your primary line so you never have to change anything. That works if you’re actively trying to maintain your life in the US, but it doesn’t give you a Spanish number, doesn’t help with local integration, and costs significantly more for the privilege. If you’re building a life in Barcelona, not just visiting it, Popcorn is solving the wrong problem.
Holiday eSIM is the only provider that includes a real phone number and unlimited calls with every European plan, at prices that undercut Holafly by 20–30% for the same duration.

A Note on Penya
Part of what makes Penya useful is that it works best in the moment, when you’re standing on a corner deciding where to eat, when a friend asks where to go on a Saturday night, when you want to share a discovery before you forget it. That requires reliable data wherever you are in the city, and wherever you travel. An eSIM that keeps you connected across Europe without roaming charges is, practically speaking, what makes the app worth having on the road.
If you’re already using Penya in Barcelona, Holiday eSIM is the connectivity layer that makes it work.
