Compare Spain eSIM plans for Madrid and Barcelona airport transfers, Seville and Valencia city transport, maps and accommodation messages. Check data, validity, listed territory, device support, tethering and total price.
A Spain itinerary can begin at a Madrid-Barajas terminal, continue through Barcelona-El Prat, use Seville's airport bus and finish on Metrovalencia. Those arrivals do not share one ticket rule: Madrid access differs by terminal, Barcelona's L9 Sud airport stations restrict some common tickets, and local routes change. Use mobile data to check the current operator page, then save the terminal, valid ticket, hotel address and a backup route offline.

Important cities in Spain
Madrid · City guide
At Adolfo Suárez Madrid-Barajas, the transport choice depends on the terminal. Aena lists Metro line 8 at the Airport T1-T2-T3 and Airport T4 stations, while the Cercanías C1 airport stop is at T4; do not assume one rail service reaches every terminal. T4S is a satellite building with an internal train connection from T4, and other terminal transfers are a separate step. Some Metro ticket types require an airport supplement, so check the current ticket rule and terminal before entering. Save the hotel address, interchange and terminal transfer plan offline.
Madrid eSIM — online before you land →Barcelona · City guide
Barcelona's L9 Sud serves the Aeroport T1 and Aeroport T2 stations, but a familiar city ticket is not automatically valid there. TMB currently identifies the single ticket, T-casual, T-grup, event tickets and other products listed by TMB among the tickets excluded at the airport stations; treat that list as current guidance, not a permanent exhaustive rule. Check the ticket page before travel and obtain a product valid for the airport journey. Download the correct terminal station, interchange and accommodation route before leaving Wi-Fi.
Barcelona eSIM — online before you land →Seville · City guide
Aena and TUSSAM identify Seville's EA Airport Special bus as the direct link between the terminal and the city. Current official guidance includes ticket purchase at the airport Arrivals point, selected machines or online channels, and onboard payment by bank card; options and conditions should be checked again for the travel date. Confirm the stop that matches the accommodation rather than relying on an old screenshot. Keep the stop name, hotel address and a backup pickup point offline in case the route or ticket channel changes.
Seville eSIM — online before you land →Valencia · City guide
At Valencia Airport, Aena places the Metrovalencia station on the ground floor of the regional-flights terminal. Lines 3 and 5 share airport access but serve different onward areas: line 3 links the centre, university area and northern metropolitan area, while line 5 links the centre and port. Check the current destination, stop, timetable and ticket before boarding instead of treating the lines as interchangeable. Save the accommodation address, chosen line and a surface-transport alternative offline for the arrival.
Valencia eSIM — online before you land →Why Horizon
Spain's major airport links use different stations, ticket conditions and destinations. A suitable data plan helps you reopen the current Aena, TMB, TUSSAM or Metrovalencia guidance, message the accommodation and adjust a route when the terminal or local connection changes. It does not replace a valid transport ticket, an offline map or checking the plan's exact territory.

Choose country, regional or global coverage and check every destination in the plan details.
Start with the data needed, trip length and exact listed territory, then compare support for an unlocked eSIM-compatible device, tethering rules and total price before checkout. A Spain label should match the destinations in Spain that you intend to visit, but it does not describe nearby countries or territories. Read the selected plan's activation and validity terms rather than assuming every product starts or renews in the same way. Keep the order email and setup guide available separately from the phone.
Install the eSIM over dependable Wi-Fi while the order email and setup guide are accessible, and save a separate copy of the guide before travel. The selected plan controls whether validity starts at installation, activation, first network use or another stated event, so follow its exact wording instead of using a general rule. Keep the profile installed after setup and wait for the plan's instruction before choosing it for mobile data. Download the first airport route, accommodation address and support details before leaving Wi-Fi.
Match the arrival terminal and city destination before buying any transport ticket; there is no single ticket rule for these airports. In Madrid, line 8 has separate T1-T2-T3 and T4 stations while Cercanías C1 reaches T4. In Barcelona, verify a product valid at the L9 Sud T1 or T2 airport station. In Seville, check the current EA Airport Special route and sales channel. In Valencia, choose line 3 for the centre, university or northern area, or line 5 for the centre or port. Recheck the operator page on the travel date and save the route offline.
Calls, SMS and tethering depend on the exact plan, while dual-SIM operation also depends on the phone and its settings. Check the product details rather than assuming a phone number, voice allowance or hotspot permission is included. Messaging and calling apps use the selected mobile-data connection according to their own account settings. If the device supports keeping both SIMs active, deliberately select the Spain eSIM as the data line when instructed and keep data roaming off on the home SIM unless you intend to use it. Test the intended arrangement before relying on it for an airport pickup.
Never infer territory from the Spain label alone. Portugal, France, Andorra, Gibraltar and Morocco must each appear explicitly in the selected plan's list before you expect service there. Check every destination on a mainland or island itinerary against that exact list as well; do not assume that a familiar geographic or political relationship determines the product territory. Verify the list before purchase and again before moving onward, then save the address, essential documents and route offline. An eSIM does not establish that a border or crossing is open or that entry is permitted.
Reconnect to dependable Wi-Fi and open the guide for the exact plan purchased. Keep the eSIM installed because deleting it may prevent reuse of the setup code. Confirm that the plan is active, its profile is selected for mobile data, and roaming, APN and network selection match the instructions; then toggle airplane mode or restart the phone if directed. If data still fails, contact support with the order number, phone model, current location, displayed network name, error text and screenshots, without sharing passwords, full payment details or other secrets.
