Cheap eSIM for Spain: the real cost per day (and the cap trap to avoid)

VoaSim team · Updated 2026-09-25

Straight answer: A VoaSim eSIM for Spain costs USD 18.90 for 5 days, USD 23.90 for 7, USD 30.90 for 10, USD 42.90 for 15, USD 61.90 for 30 and USD 106.90 for 60 days, with today's 15% promo. Data is truly unlimited, so the daily cost drops from USD 3.78 to USD 1.78 as the trip gets longer, and it never grows with usage.

Key facts

  • VoaSim prices for Spain run from USD 18.90 (5 days) to USD 106.90 (60 days), with the same price for every destination.
  • The per-day cost falls from USD 3.78 on the 5-day plan to USD 1.78 on the 60-day plan, so longer trips pay less per day.
  • Data is truly unlimited — no cap, no throttling, no fair-use clause — so the price never grows with Maps, video calls or uploads.
  • A second eSIM in the same order gets an extra 10% off; trips of 1 to 4 days pay the 5-day package.
  • The eSIM connects automatically to Movistar, Vodafone or Orange on 4G and, where available, 5G, including Ibiza, Mallorca and the Madrid–Barcelona AVE.

"Cheap" is easy to advertise and hard to measure. A 1 GB plan for Spain can look like the best deal in the store and still cost you more than an unlimited one, because Google Maps, Instagram stories and a couple of video calls from Barcelona burn through a small bucket in two days.

This page does the boring math: what VoaSim charges per day for Spain, how the price moves with trip length, and when a by-GB plan is genuinely the cheaper choice.

VoaSim price list for Spain (per plan and per day)

One price per duration, the same for Spain or any of the 170 destinations we cover. Prices below already include today's 15% promo.

PlanTotal priceCost per day
5 daysUSD 18.90USD 3.78
7 daysUSD 23.90USD 3.41
10 daysUSD 30.90USD 3.09
15 daysUSD 42.90USD 2.86
30 daysUSD 61.90USD 2.06
60 daysUSD 106.90USD 1.78

Two rules worth knowing before you buy: trips of 1 to 4 days pay the 5-day package, and one eSIM covers a maximum of 90 days. Add a second eSIM to the same order (for a partner or a second phone) and it gets an extra 10% off. Run your exact dates in the price simulator to see the final number.

Why the longer plan is always the cheaper one

The per-day column above is the whole story. A 5-day plan costs USD 3.78 a day; the 60-day plan costs USD 1.78 a day, less than half. If your trip lands between two durations, compare both totals before you decide.

Example: 12 days in Spain. The 15-day plan at USD 42.90 costs less than buying a 10-day plan and then a 5-day top-up (USD 30.90 + USD 18.90 = USD 49.80). Same idea at 25 days: the 30-day plan at USD 61.90 beats 15 + 10 days.

Days start counting at the eSIM's first connection to a network in Spain, not at purchase. So buying early costs you nothing in lost days. Install at home, keep the eSIM line switched off, and turn it on after you land in Madrid or Barcelona. There is no early-booking discount on this site — the table price is the price.

The cap trap: when a "cheap" GB plan stops being cheap

Most eSIM brands sell Spain by the gigabyte: 1 GB, 3 GB, 5 GB, valid for a set number of days. The headline price looks low. Then the trip starts.

What actually eats data in Spain:

When the bucket empties you either buy a top-up at full price or spend the evening hunting for hotel Wi-Fi. That second purchase is where the cheap plan quietly becomes the expensive one. With VoaSim there is no data cap, no speed throttling and no hidden "fair use" clause, so the number you paid on day one is the number you paid on day ten. If you are only checking email for two days, a small GB plan may genuinely be cheaper — see the honest comparison page.

Coverage in Spain: networks, cities and islands

The eSIM connects automatically to Spanish networks — Movistar, Vodafone and Orange — on 4G and, where available, 5G. You do not pick the operator; the phone selects the strongest signal.

In practice that means service in Madrid, Barcelona, Seville, Valencia, plus solid coverage on the islands, Ibiza and Mallorca included. It works on the high-speed trains between Madrid and Barcelona, with the usual tunnel drops any network has.

Two limits to plan around. If your trip includes a Mediterranean cruise, the eSIM works on land at ports, not at sea. And if you are hopping to other European countries, the same eSIM already covers 50 of them, including Portugal, France, Italy, the UK, Switzerland and Turkey — details on the Europe plan page. No need to buy one eSIM per border.

What you get for the price (and what you don't)

Being clear about this saves refund requests. The VoaSim eSIM for Spain is a data-only product. You do not get a Spanish phone number and you cannot make traditional voice calls. Everything that runs on data works normally: WhatsApp, FaceTime, Telegram, Maps, banking apps, ride-hailing, email.

Your physical SIM and your home number stay in the phone, so WhatsApp keeps working on your usual number. Just switch off data roaming on your home carrier so it never bills you.

The QR code arrives by email within minutes of payment. Install it before you fly — there are step-by-step guides for iPhone and Android in the guides section. Payment is by international credit or debit card in USD through Stripe, invoice by email, no hidden fees. On hotspot/tethering: don't count on it, ask support first. And if the eSIM will not connect and support cannot fix it, you get a 100% refund.

Will your phone take it? Quick compatibility check

Dial *#06# on the keypad. If an EID number appears alongside the IMEI, the phone supports eSIM. That test works on any brand.

As a rule: iPhone XR or newer, Samsung Galaxy S20 or newer, Google Pixel 3 or newer, and most phones released from 2020 on. One extra condition: the handset must be carrier-unlocked. A phone still locked to a US or UK operator will refuse any foreign profile, and that has nothing to do with the eSIM you bought. Check with your carrier before the trip.

VoaSim does not sell physical SIM cards, so an older phone without eSIM support won't work with us. If you already have an eSIM from any brand and it shows no signal in Spain, the free eSIM Rescue tool runs a diagnosis. Still unsure about buying online? Read how we operate 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

What is the cheapest eSIM for Spain at VoaSim?
The lowest total is the 5-day plan at USD 18.90. The lowest cost per day is the 60-day plan at USD 1.78 per day, USD 106.90 in total. Which one is cheapest for you depends entirely on how long you stay in Spain.
Is unlimited data really unlimited?
Yes. No data cap, no speed throttling after a certain volume, and no hidden fair-use clause. You pay once for the number of days you chose and use as much data as you need in Spain, from Maps all day to video calls every night.
When do my days start counting?
At the eSIM's first connection to a network in Spain, not at purchase. Install the QR code at home and keep the eSIM line switched off until you land. On Android, do not enable the eSIM's mobile data before the trip, or the clock may start early.
Can I use the same eSIM in Portugal or France?
Yes. The Europe plan covers 50 countries with one eSIM, including Portugal, France, Italy, the UK, Switzerland, Norway, Iceland and Turkey. If your itinerary crosses borders, you do not need a separate eSIM for each country, and the price does not change.
Do I get a Spanish phone number?
No. This is a data-only eSIM, so there is no Spanish number and no traditional voice calls. Your own SIM and number stay in the phone, so WhatsApp, iMessage and app calls keep working on your usual number over the eSIM's data connection.
Is there a discount for two people travelling together?
Yes. Add a second eSIM to the same order and it gets an extra 10% off on top of the listed price. Each eSIM is independent, so both travellers get their own unlimited data instead of sharing one phone's hotspot.
What if the eSIM doesn't connect in Spain?
Contact support by chat or at hola@voasim.com, or run the free eSIM Rescue tool at voasim.com/sos, which diagnoses eSIMs of any brand. If we cannot get you connected, you get a 100% refund of what you paid.
