TL;DR
- Best value for money: Saily – the cheapest way for a non-EU visitor to land in Spain with data already working, with an optional number for calls and texts, and it travels across the rest of Europe on the same eSIM.
- Best for buying direct from a national carrier: Orange Travel – the traditional carrier plan, worth it if a genuinely European number and in-person support matter more to you than an app-based setup.
- Strongest 5G network: Vodafone Travel – runs on Vodafone’s own Spanish network, but the visitor plan is data-only with no number.
- Evaluation criteria used: local network priority, calls and a local number, price, activation friction, prepaid terms.
Spain gives non-EU visitors three honest ways to get online, and on price, Saily is the cheaper way in: Spain plans start at US$3.99, activate before you land, and still leave room for an optional number if you want to add calls. Vodafone Travel and Orange Travel earn their keep elsewhere, on raw 5G speed and on buying direct from an established carrier, so the right pick still depends on price, network quality, and whether a locally recognized number matters to you.
A wrong choice costs you a week of international roaming rates, or an hour finding a shop that sells tourist SIMs. Both are avoidable in about four minutes from your phone. Here is where each option lands for a trip to Spain in 2026.

First, Check Whether You Even Need to Pay
EU residents already roam free across Spain, so half the people reading this can stop here. Under the EU’s “Roam like at home” rules, anyone with a plan from an EU or EEA operator uses calls, texts, and data at their domestic rate in all 27 member states, Spain included, at no extra charge [1][2].
Non-EU visitors get no such protection. If you are flying in from the United States, the United Kingdom, Canada, Australia, or anywhere outside the roaming area, your home carrier bills you at full international rates, and that is exactly the gap a travel eSIM or a Spanish carrier plan fills [2].
This guide speaks to that second group. If your SIM is from outside the EU, the three options below are your realistic shortlist, and the differences between them are bigger than the price tags suggest.
How We Compared the Three
Every option here sells mobile data in Spain, so the tie-breakers are what you do beyond raw gigabytes. We judged all three against five things that decide a real trip:
- Local network priority: whether the plan runs on a top-tier Spanish network or rides partner agreements, which decides real-world speed and reliability.
- Calls and a local number: whether voice minutes and a reachable number are included by default, or available only as an add-on.
- Price: entry cost and cost per gigabyte, not the headline promotion.
- Activation friction: can you set it up before you fly and connect on landing, or does setup need a connection you will not have yet.
- Prepaid terms: activation windows, validity, top-ups, and hotspot rights.
Travel eSIM or Local Carrier in Spain: The Three Options Compared
| # | Provider | Best For | Standout Feature |
| 1 | Saily | Best value for money | Built-in security, one eSIM for Europe |
| 2 | Orange Travel | Buying direct from a national carrier | Direct carrier purchase with in-store support and top-ups |
| 3 | Vodafone Travel | Strongest 5G network | Runs on Vodafone Spain directly |
Saily – Best Value for Money
Saily sells country, regional, and global eSIM data plans through an app that also ships ad-blocking, malicious-site protection, and virtual location. It is built by Nord Security, the company behind NordVPN, and it is the travel eSIM that bundles those security tools inside the same app that sells the data, which data-only eSIM sellers and carrier plans do not do.
For Spain, plans start at US$3.99 for 1 GB over 7 days and run up to Saily Ultra’s unlimited data plan, and the same eSIM covers 200+ destinations, so one profile carries you across the rest of Europe too. An optional Saily phone number add-on brings voice calls and SMS to any plan, so a number is there if you want one.
That value read is not just ours. Cybernews ranks Saily the top eSIM for Europe on coverage and affordability, and TechRadar credits its NordVPN parentage for an easy, user-friendly setup [4][5].
“Have used Saily for travel esim for several years now across several countries both in the EU and out (Spain, Cyprus, Tenerife and Mexico to name a few). Never had an issue and works very well.” TylerP, 5 stars on Trustpilot
Pros:
- Spain plans from US$3.99, among the cheapest ways to land connected
- Ships 115+ virtual locations, an in-app ad blocker, and web protection no carrier plan here includes
- One eSIM covers 200+ destinations, so a multi-country Europe trip needs no new profile
- Plans activate automatically on arrival, so you install before you fly and skip the SIM queue
- Saily Ultra adds unlimited global data for heavier trips, beyond the standard country plans
- An optional Saily phone number brings voice calls and SMS to the plan, so you’re not limited to data alone
Cons:
- Rides local partner networks rather than owning one, so speed varies by area
Best for: Non-EU visitors who want the cheapest, fastest route to working data in Spain and beyond, with a number available only if they need one.
Orange Travel – Best for Buying Direct From a National Carrier
Orange Travel sells prepaid travel eSIMs and SIMs that pair Spanish and European data with a European phone number, plus calls and texts within Europe, bought directly from a national carrier rather than an app-based reseller. Plans are installed by QR code, include a mobile hotspot, and let you top up while keeping the same number.
Orange genuinely beats an app-based eSIM on one point: it is bought directly from a carrier with a physical presence across Spain, so a traveler who wants an established operator name, in-person support, or the option to walk into a store if something goes wrong gets that here in a way no app-only eSIM offers.
Pros:
- A European number with calls and texts across Europe, bought directly from a national carrier rather than an app reseller
- Mobile hotspot and top-ups, with the number kept when you top up
- Backed by Orange’s own strong network footprint in Spain and across the continent
Cons:
- Costs more per gigabyte than a standalone data eSIM plan
- The included number is European rather than always a local Spanish one
- No built-in security tools, and the buying flow is less streamlined than a dedicated eSIM app
Best for: Visitors who would rather buy a plan directly from an established carrier, especially if they want a number recognized as genuinely European rather than a US-based add-on.
Vodafone Travel – Best for the Strongest 5G Network
Vodafone Travel runs a prepaid travel eSIM platform, and Vodafone Spain’s visitor product, DataOnly, sells 5G data on Vodafone’s own Spanish network with no contract and no phone number [3]. It is the pick for raw network quality, because you are on one of Spain’s top-tier networks directly rather than through a partner agreement. You buy online, receive a QR code within a minute, and have up to 60 days to activate before the clock starts [3].
The catch sits in the name. DataOnly gives you no number and no voice minutes, so it competes mostly on data speed rather than the calls or number Orange includes, without the multi-country reach or security tools an app-based eSIM like Saily adds.
Pros:
- Runs directly on Vodafone Spain’s network, strong for 5G speed and reliability
- No daily data cap, with a generous activation window before use begins
- Fully digital setup, with an instant QR code and no store visit
- Larger data bundles work out cheaper per gigabyte than a small entry-level eSIM plan, which favors heavy data users over a longer stay
Cons:
- Data-only, so it drops the calls and number a carrier plan could offer
- Spain-focused, without one-eSIM coverage for a wider Europe trip
- No built-in security features, and entry pricing sits above app-based eSIMs
Best for: Visitors who want the strongest possible 5G data in Spain specifically and do not need voice or a number.
Which Should You Actually Pick?
No single option here fits every traveler, so match your situation to the right one:
- If you carry an EU or EEA SIM: you likely need none of these. “Roam like at home” already covers your calls, texts, and data in Spain at your domestic rate [1].
- If you are a non-EU visitor who mainly needs data: Saily is the best value. It lands you online cheaply, activates on arrival, and follows you to the next country on one eSIM.
- If you want a number bought direct from an established European carrier: Orange Travel is the clearer choice, especially if you would rather manage things in person than through an app.
- If you want the strongest 5G and no number: Vodafone’s DataOnly plan puts you on a top Spanish network directly, which matters most for heavy streaming or hotspot use.
- If you are hopping across several countries or working remotely: Saily’s regional and global plans keep one eSIM running the whole trip.
For most short visits to Spain, the honest answer is a travel eSIM, and Saily gives the most for the least. Reach for a carrier plan when you specifically want to buy direct from an established operator.
FAQs
Is a travel eSIM cheaper than a local SIM in Spain?
A travel eSIM is usually the cheaper and easier option for short trips, with Saily’s Spain plans starting near US$4 and no shop visit required. A local prepaid SIM can edge it on price per gigabyte if you have time to find a store and register with your passport, though airport SIMs are often overpriced.
Do I need to enable data roaming for a travel eSIM in Spain?
Yes, you turn on data roaming for the eSIM line, and that is normal, not an extra charge. The setting simply lets the eSIM connect to Spain’s local networks; keep roaming off on your home SIM so it stays idle.
Can I get a local Spanish phone number with a travel eSIM?
Not a native Spanish one. Saily’s optional phone number add-on gives you a US line for calls and texts, and Vodafone’s DataOnly plan skips a number entirely. If a genuinely European number matters, a carrier plan like Orange Travel is built for that.
Does Saily work as soon as I land in Spain?
Saily activates automatically when you arrive, so you install it before you fly and connect on landing. You have a 30-day window to reach Spain before the plan starts, and the app alerts you at 80% of your data.
Does Saily include security features the carriers don’t?
Yes, Saily ships 115+ virtual locations, an in-app ad blocker, and malicious-site protection, none of which the Spanish carrier plans here include. That security layer is a direct inheritance from its Nord Security parentage and the clearest reason to pick it over a data-only rival.
The Bottom Line
For most non-EU visitors, a travel eSIM is the better call in Spain, and Saily is the best value, with plans from US$3.99, an optional Saily phone number for calls and texts, a Saily Ultra unlimited option for bigger trips, instant activation on arrival, one eSIM across Europe, and security tools no carrier plan here matches. Orange Travel wins if you would rather buy direct from an established European carrier, and Vodafone’s DataOnly plan is the strongest raw 5G if you want data alone. EU residents already roam free and probably need none of them. Decide on your priorities first, then price, and the choice makes itself.
