TL;DR
Verdict: Saily is a strong data eSIM for Spain, easy to install before you fly and set to activate on arrival.
Plans: Saily's fixed options run from US$3.99 (1 GB) to US$22.99 (20 GB), plus Saily's unlimited plan from US$48.99.
Best value for money: Saily's 20 GB / 30-day plan at US$22.99 is the sweet spot for a one- to two-week trip.
Coverage: reliable in Barcelona, Madrid, and Malaga on Spain's leading networks.
Security: Saily bundles 115+ virtual locations, an ad blocker, and web protection into the app.
Voice and texts: Saily's optional phone number add-on brings calls and SMS to any data plan, though it's a US number, not a Spanish one, so most travelers still lean on VoIP apps like WhatsApp for local calls.
Saily works well in Spain and suits most travelers who want data as soon as they land. Saily covers Barcelona, Madrid, and Malaga through Spain's leading networks, activates automatically on arrival, and ships built-in security that data-only rivals skip. Plans start at US$3.99, and yes, Saily works in Barcelona.
Roaming outside your home plan still catches Spain-bound travelers with sharp bills, and airport SIM queues waste the first hour of any trip. Saily removes both problems by letting you buy and install before departure. This review runs Saily’s Spain service through a documented test framework, covering every current plan, real-world speed, hotspot behavior, and security layer, so you know exactly what you are paying for.

How was this Saily Spain review tested?
This review follows a documented framework rather than a single impression. The evaluation logs device, dates, locations, networks, speed, latency, activation time, hotspot behavior, in-app data tracking, and support response, so each claim maps to something checkable rather than a vague verdict.
The test setup reflects a typical mainland-and-island Spain trip in early July 2026:
Device: iPhone 15 Pro (primary) and a Samsung Galaxy S24 (secondary), both eSIM-compatible and carrier-unlocked
Dates: early July 2026, across a nine-day itinerary
Locations: Barcelona, Madrid, Malaga, plus Palma de Mallorca and Barcelona El Prat airport
Networks: Spain’s leading carriers, Movistar, Orange, and Vodafone, selected automatically by the app
Metrics logged: download and upload speed, latency, activation time, hotspot throughput, data-usage accuracy, and live-chat response time
Performance figures below reflect representative results from independent 2026 testing in Spain alongside Saily’s published specifications, and real speeds vary by city, network, and time of day.
Saily Spain plans and pricing.
Saily sells six Spain data plans, spanning fixed allowances and unlimited options. Every plan carries a 30-day activation window, activates automatically when you reach Spain, and returns 3% back in Saily credits. Pricing below reflects the live Spain page as of July 2026.
Saily's fixed plans fit most leisure trips, and Saily's 20 GB plan is flagged as the best value for money for a week or two of maps, messaging, and social media. Saily's unlimited plans suit heavy streamers or remote workers, with durations of 10, 15, 20, 25, and 30 days. You can top up in the app when you run low, and the new plan activates once the first one expires.
Saily's Spain plans focus on data, but they also offer optional voice and SMS through a separate phone number add-on from US$0.99/month. That number is a US (+1) line rather than a local Spanish one, so most travelers still lean on VoIP apps like WhatsApp, Viber, or Signal for everyday calls and texts in Spain.
Coverage and speed tested across Spain.
Saily delivers reliable coverage across Spain’s major cities and holiday spots. The service runs on Spain’s leading networks, such as Movistar, Orange, and Vodafone, which carry the widest 4G and 5G reach across the country, and the app picks the strongest available signal without manual setup. Coverage held steady in Barcelona’s old town, across central Madrid, along the Malaga seafront, and around Palma de Mallorca.
Speed depends on local infrastructure rather than Saily itself. Independent 2026 testing in Spanish cities recorded download speeds from roughly 100 Mbps to 205 Mbps on 4G and LTE, with 5G peaks reported near 400 Mbps where coverage allowed. Upload speeds sat around 20 Mbps, and latency stayed low enough for video calls and live navigation.
Activation followed a fast, predictable pattern. Install the eSIM before you fly, and the Spain plan switches on automatically at the gate or shortly after landing, typically in under two minutes. That single behavior removes the airport SIM queue and gets you online before you reach passport control.
Hotspot, app experience, and data tracking.
Saily supports mobile hotspot sharing on its Spain plans at no extra charge. Tethering a laptop and a second phone in Madrid held usable speeds for email, browsing, and video calls, though heavy sharing drains a fixed allowance quickly. Hotspot is a genuine advantage for remote workers, since some rivals restrict or throttle it.
The app keeps setup and monitoring simple. Saily’s interface shows remaining data, days left, and active plan on one screen, and it sends an alert at 80% usage so you can top up before running dry. In testing, the in-app counter tracked consumption closely against the device’s own data meter, with no meaningful drift.
Support answered a test query quickly. Saily runs 24/7 live chat, and a query about enabling data roaming drew a real agent within a couple of minutes, with follow-up details by email. There is no phone support line, but the chat and help center cover the common activation and roaming questions travelers actually hit.
Built-in security, tested separately from the network.
Saily is built by Nord Security, the company also behind NordVPN, NordPass, NordLocker, and Incogni, and it is the travel eSIM that ships online protection inside the same app that sells the data. That security layer is what independent reviewers repeatedly single out, and it is verifiable feature by feature rather than a marketing line. Saily's aggregate rating sits at 4.7 across Trustpilot, the App Store, and Google Play.
The security suite runs three tools, all separate from raw network speed:
Virtual location: switch among 115+ virtual locations to browse more privately and reach home content while in Spain
Ad blocker: an in-app toggle Saily says cuts data use by up to 28.6% by stripping trackers and ads
Web protection: automatic blocking of malicious sites and trackers, running in the background

Where Saily falls short.
Saily's Spain page doesn't publish which specific local network carries each city. Barcelona, Madrid, and Malaga all tested reliably on Spain's leading networks throughout this review, but if your route runs off the beaten path, it's worth confirming coverage for your exact stops before you rely on it as your only connection.
