Top 10 eSIM providers for Madrid in 2026
Madrid's deep Metro tunnels and limited free Wi-Fi make reliable mobile data worth sorting before you land at Barajas. Holafly's unlimited plans on Movistar's network hold signal through the oldest Line 1 stations and activate by QR in under 5 minutes. The flat daily rate, currently around €6 for a 5-day plan, removes per-GB anxiety for visitors burning through maps and translation apps.
Madrid's three carriers, Movistar, Vodafone, and Orange, each run their own tower infrastructure across the Comunidad de Madrid. Above ground, their 4G and 5G footprints overlap almost completely. You'll get a strong signal streaming from a Retiro Park bench or standing in the Puerta del Sol pedestrian zone on any of them. Underground is where the choice starts to matter. The Metro system has over 300 stations, some that date to Line 1's 1919 inauguration, and the deeper tunnels still favor Movistar's repeaters over the other two. The stretch under Malasaña between Tribunal and Bilbao is a reliable litmus test. Line 8 from Nuevos Ministerios out to Aeropuerto T4 is another. Most international eSIM providers ride one of these three networks, but a few use smaller wholesale carriers that lose signal entirely in those older stations. Madrid visitors also tend to burn more data than they expect. Between maps, translation apps, and El Tenedor searches for a dinner spot, 1.5 to 3 GB per day is normal, which means a 5-day trip can hit 10 GB without you noticing.
Free Wi-Fi in Madrid is patchier than most visitors expect. Cafés in Chueca and Chamberí still tend to require a purchase and a password request, and the municipal MadridWiFi network covers the sunlit plazas around Plaza Mayor but drops the moment you step inside a stone-walled bar on a side street. You're relying on mobile data more than you might in Lisbon or Amsterdam, which makes your carrier choice load-bearing. A 3 GB plan on an off-brand MVNO sounds fine at €4 until your map freezes as you thread the narrow alleys of Lavapiés at midnight. Movistar tends to have the edge inside the older Metro tunnels, particularly between Ópera and La Latina where Line 2 and Line 5 cross at depths the original 1920s engineers never planned for mobile repeaters. To be fair, all three major networks handle the newer extensions toward Pinar de Chamartín and Hospital Infanta Sofía well. It's the pre-war tunnels south of Gran Vía where you feel the difference.
Holafly is not the right pick for everyone. If you're staying longer than 15 days, Airalo or a local Vodafone eSIM from their shop near Callao tends to work out cheaper per GB. Holafly's unlimited plans currently cap at 90 days, and their per-day pricing above the 15-day tier rises to around €2.70 per day. Budget travellers spending most of their time in well-connected areas like Salamanca or Retiro might find that a 5 GB Saily plan at €11.99 covers a full week without the unlimited premium. And if you need a local Spanish number for booking restaurants through El Tenedor or receiving SMS confirmations from Renfe, Holafly won't help. You'll want Orange or Movistar's eSIM for that, both of which assign a +34 number.
The full list
-
Holafly
Unlimited data on Movistar's network means solid coverage from Barajas T4 arrivals through the deepest Metro Line 1 tunnels under Sol. QR activation takes under 5 minutes, and flat-rate pricing at roughly €6.10 per day for a 5-day plan removes any metering anxiety while navigating Lavapiés or finding your way to a Malasaña bar at 2 AM.
-
Airalo
Offers 13 Spain-specific plans starting at €4.50 for 1 GB, riding either Movistar or Orange infrastructure depending on the package. Reliable above ground in Salamanca and Retiro, though a few users report brief signal drops in the older Metro stations between Ópera and La Latina. The app's coverage map lets you verify your hotel's district before buying.
-
Orange Spain eSIM
Orange's own eSIM gives you a local +34 number, useful for booking through El Tenedor or receiving confirmation texts from Renfe train tickets. Coverage across Chamberí and the Casa de Campo area is strong. Activation requires scanning a QR from their website or visiting the Orange shop on Gran Vía 28.
-
Vodafone Spain eSIM
Vodafone assigns a Spanish +34 number and currently offers a tourist eSIM at €20 for 10 GB valid 30 days. Their 5G coverage around the Salamanca district and along the Paseo de la Castellana tends to be the fastest of the three major carriers. The Callao shop near Sol can help with activation if the QR process stalls.
-
Saily
Budget-friendly at €4.49 for 1 GB or €11.99 for 5 GB on 30-day validity. Rides Movistar's network in Madrid, so tunnel coverage on Line 8 to Barajas stays consistent. No local number, but for visitors focused on maps and translation apps while walking between Puerta del Sol and the Prado, the 5 GB tier likely covers a full week.
-
Nomad eSIM
Competitive per-GB pricing at around €2 per GB for their 10 GB Spain plan. Uses Orange's infrastructure in the Madrid area, giving solid coverage across Atocha station and the Méndez Álvaro bus terminal. QR delivery is fast, usually within 2 minutes of purchase. Worth noting that their 3 GB plan tends to run out quickly if you're using navigation daily.
-
Ubigi
Available through their app or directly on Samsung and Google Pixel devices. €9.50 for 3 GB on a 30-day window. Coverage runs on Orange Spain, and signal holds well along the Cercanías commuter line from Atocha to Chamartín. No hidden fees reported in recent reviews, though top-up pricing above the base plan rises to about €4 per GB.
-
Maya Mobile
Offers a 5 GB Spain plan at around €8.99 with 30-day validity. Coverage piggybacks on Vodafone's network, which performs well in the Chamartín business district and the newer Metro extensions toward Las Tablas. Activation is QR-only, no app required. A decent mid-range option if you're splitting time between central Madrid and the northern office parks along the A-1.
-
Yesim
Swiss-based provider with a €7.90 plan for 3 GB in Spain. Their network partner in Madrid is Movistar, so underground Metro coverage is generally reliable. The app interface feels dated compared to Airalo or Holafly, and a few users report slow customer support responses. Coverage around the Adolfo Suárez Madrid-Barajas T4S satellite terminal holds steady.
-
Movistar eSIM
Spain's largest carrier by subscriber count, with the deepest Metro tunnel coverage in Madrid. Their prepaid eSIM starts at €10 for 5 GB. The catch is activation. You'll likely need to visit a Movistar shop, and the ones near Sol can have weekend queues of 30 minutes or more. Worth it if underground signal between Tribunal and Tirso de Molina matters to your daily route.
