Spain is an easy country to stay connected in. Coverage in Madrid, Barcelona, Seville, Valencia, Ibiza and Mallorca is solid, and the local networks — Movistar, Vodafone and Orange — reach far beyond the big cities. The question is not whether an eSIM works in Spain. It's which one fits how you travel.

This guide lays out what the VoaSim eSIM for Spain costs, how it differs from the brands that sell data by the gigabyte, and when a different option is honestly the smarter buy.

How the VoaSim eSIM works in Spain

The eSIM connects automatically to local Spanish networks — Movistar, Vodafone or Orange, whichever is strongest where you are — on 4G and, where available, 5G. You don't choose a carrier or enter any settings; the phone picks the best signal as you move.

That matters on a Spain trip because you rarely stay put. You land in Madrid, take the high-speed train to Barcelona, then hop to Mallorca or Ibiza. The same eSIM keeps working on all of it, including along the AVE corridor, with the usual tunnel gaps any network has.

It's a data-only product. You don't get a Spanish phone number, and traditional voice calls aren't included. But WhatsApp, FaceTime, Telegram, Google Maps, Renfe and Uber all run over data, which is what almost everyone actually uses. Your physical SIM and your own number stay active in the phone — just turn off your home carrier's data roaming so nothing bills you twice.

Trips of 1 to 4 days pay the 5-day package. The maximum per eSIM is 90 days. Adding a second eSIM to the same order — for a partner or a second phone — takes 10% extra off that line.

Unlimited vs. per-GB: which one fits your trip

Most eSIM brands for Spain sell buckets of gigabytes. Airalo, Nomad, Saily, Ubigi, Maya Mobile, GigSky, Alosim and others work that way: you pick 3 GB, 10 GB, 20 GB, and when it runs out you top up in the app. Holafly sells unlimited plans with usage conditions and tethering rules written into its terms. Rules, caps and validity differ by brand, so read the terms on each official site before buying.

The practical split is simple. If you mostly use hotel and café Wi-Fi and only need maps and messages outside, a small per-GB package can come out cheaper. If you stream on the train, upload photos and videos daily, use Maps all day, or share the trip with people back home, a data cap turns into a chore — checking a balance, topping up, guessing.

VoaSim's pitch is that there's nothing to count: no data cap, no speed throttling, no hidden fair-use clause. See the wider comparison page for how the categories stack up.

When a local SIM or a by-GB plan is the better pick

Being fair about it: VoaSim isn't the right answer for everyone in Spain.

Install before you fly: the 5-minute setup

Buy, install, don't activate. That's the order.

  1. Pick your dates in the simulator and pay by card. The QR code lands in your email within minutes (plus a WhatsApp heads-up if you left a number).
  2. Scan the QR at home, on Wi-Fi, following the iPhone or Android guide that comes with it.
  3. Leave the eSIM line switched off. On Android, do not turn on the eSIM's mobile data before the trip.
  4. When you land in Madrid, Barcelona or Palma, switch the eSIM line on, set it as the data line, and turn off data roaming on your home SIM.

Your days start counting at the eSIM's first connection to a network in Spain, not at purchase — which is exactly why you keep it off until arrival. Airport Wi-Fi at Barajas or El Prat is free if you need a minute to finish setup; our airport guide covers arrivals.

If anything looks wrong, the free eSIM Rescue tool diagnoses an eSIM with no signal — any brand, not just ours.

Will your phone work? Compatibility check

Thirty seconds settles it: dial *#06#. If an EID number appears alongside the IMEI, the phone supports eSIM.

As a rule of thumb, iPhone XR and newer, Samsung Galaxy S20 and newer, Google Pixel 3 and newer, and most phones released from 2020 onward are compatible. One catch that trips people up: a phone locked to a carrier won't accept another operator's eSIM, so unlock it before you travel — your carrier does this, usually for free once the device is paid off.

Two more things worth knowing before Spain. Cruises out of Barcelona or Málaga: the eSIM works on land, at the ports, not at sea. And if Spain is one leg of a bigger European trip, the Europe plan covers 50 countries on a single eSIM — including Switzerland, the UK, Turkey, Norway and Iceland — at the same prices listed above.

If the eSIM won't connect and support can't fix it, you get a 100% refund. Details on the trust page.

Why trust VoaSim?

Registered company with an invoice on every purchase, USD payment via Stripe with no hidden fees, human support and a guarantee: if the eSIM will not connect and support cannot fix it, you get 100% back.

FAQ

How much does an eSIM for Spain cost with VoaSim?
USD 18.90 for 5 days, USD 23.90 for 7 days, USD 30.90 for 10 days, USD 42.90 for 15 days, USD 61.90 for 30 days and USD 106.90 for 60 days, with today's 15% promo applied. Every plan has truly unlimited data, and the price is the same for all 170 destinations.
Which Spanish networks does the eSIM use?
It connects automatically to local networks — Movistar, Vodafone and Orange — on 4G and, where available, 5G. You don't pick one manually. The phone latches onto whichever signal is strongest as you move between Madrid, Barcelona, Seville, Valencia and the islands.
Does it work on the AVE train between Madrid and Barcelona?
Yes. The eSIM uses the same Spanish networks that cover the high-speed corridor, so you stay connected along the route. Expect brief drops inside tunnels, exactly as any local SIM or phone would have on that line.
When do my days start counting?
At the eSIM's first connection to a network in Spain, not when you buy it. Install the QR code at home while you still have Wi-Fi, then leave the eSIM line switched off until you land. On Android, don't turn on the eSIM's mobile data before the trip.
Do I keep my own phone number in Spain?
Yes. Your physical SIM stays in the phone and your number stays active, so WhatsApp keeps running on your usual number. The VoaSim eSIM is data only — no Spanish number and no traditional voice calls. Just switch off your home carrier's data roaming to avoid extra charges.
Is VoaSim cheaper than buying a Spanish SIM at the airport?
For short trips, usually yes once you count the time. A local prepaid SIM means finding a shop, registering with your passport and swapping your SIM out, which removes your home number. A local SIM makes more sense for stays of several months or if you need a Spanish phone number.
Can I use the eSIM as a hotspot for my laptop?
Don't count on it without checking. Hotspot and tethering availability depends on the plan, so contact support at hola@voasim.com or on-site chat and confirm before you rely on it for work in Spain.
