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.

VoaSim prices for Spain: one price per duration
VoaSim charges the same price for every destination. Spain costs what Japan costs. Prices below already include today's 15% promo.

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.
Payment is by international credit or debit card in USD through Stripe, with an invoice by email and no hidden fees. Run your exact dates in the price simulator to see the final number.
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.
- Very light use. A weekend where you only need Maps twice a day? A small GB package from an app-based brand may cost less than USD 18.90.
- Very long stays. Moving to Spain for a semester or a year? A Spanish prepaid SIM from Movistar, Vodafone or Orange gives you a local number and long-term pricing. It needs a shop visit, passport registration and swapping your SIM out.
- You need a Spanish number. For bank SMS codes or local landline calls, a physical Spanish SIM is the answer. VoaSim doesn't sell physical SIMs.
- You count on tethering. Don't assume it. Hotspot availability depends on the plan — ask support before you rely on a laptop over your phone.
- Carrier roaming. T-Mobile, AT&T, Verizon, EE, Vodafone and others charge per day or bundle Spain in. Check the current rate in your carrier app; our roaming overview explains what to look for.
Install before you fly: the 5-minute setup
Buy, install, don't activate. That's the order.
- 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).
- Scan the QR at home, on Wi-Fi, following the iPhone or Android guide that comes with it.
- Leave the eSIM line switched off. On Android, do not turn on the eSIM's mobile data before the trip.
- 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.

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.
