No — Madrid and Barcelona's metro systems have no cellular coverage on most underground sections. Signal returns at surface and elevated stations like Passeig de Gràcia or Argüelles. Activate your TMB ticket before you descend, or buy a paper T-Casual at the machine as a backup.

LTE works in towns along the French Way — Sarria, Portomarín, Santiago — but expect dead zones in Galician forests between them on all carriers. Download offline maps and your albergue addresses before you leave the last town with signal.

Coastal clubs, beaches, and Ibiza Town get strong 5G on Movistar and Vodafone. The interior — Sant Josep, Santa Agnès — has weak LTE on Orange and Yoigo. If you are staying inland, Movistar or Vodafone coverage is more reliable.

Two to four gigabytes covers most travelers: WhatsApp chats and calls, Google Maps navigation, Renfe and TMB app ticket validation, and occasional photo uploads. If you are streaming video on AVE trains or uploading full-resolution photos daily, add another two gigabytes.

Yes — WhatsApp voice and video calls work over the eSIM's data connection. You will not have a Spanish phone number for traditional cellular calls, but most travelers route everything through WhatsApp, FaceTime, or similar apps anyway.

Yes — Renfe's app validates AVE and Cercanías tickets via QR codes that refresh in real time. The app rejects offline screenshots, so keep the eSIM active to pull platform assignments at Madrid Atocha or Barcelona Sants five minutes before departure.

Movistar has the most extensive 5G rollout in Madrid — Retiro, Malasaña, and the airport corridor all deliver 200+ Mbps. Vodafone Spain matches that in the city center but thins out faster in suburban areas like Alcalá de Henares. The eSIM hands off between both automatically.

Yes — the TMB app activates metro and bus tickets only when you have live data. The Metro has no signal underground, so activate your T-Casual ticket before you descend. The paper card is the offline alternative but less flexible for multi-day trips.

Yes — Movistar and Vodafone Spain both deliver strong 5G in Valencia's city center and along the Turia Gardens. Coverage extends to the beach suburbs and the port. The AP-7 motorway north and south of the city has continuous LTE on all carriers.

An airport SIM at Madrid Barajas or Barcelona El Prat costs €20–30 for a week, requires a passport photocopy, and locks you to one carrier's coverage map. The eSIM costs less, installs in thirty seconds, and hands off between Movistar, Vodafone, Orange, and Yoigo automatically.

Yes — Movistar and Vodafone Spain both deliver strong LTE in Seville's old quarter, though 5G is patchy inside thick stone buildings. Tussam's bus app needs live data for real-time arrivals and mobile ticket validation. Coverage thins fast in Doñana National Park.

Yes — hotspot is enabled by default on esima eSIMs, so you can tether a laptop, share data with a travel companion, or connect a tablet without extra cost. No throttling on the first five gigabytes like some Spanish carrier tourist bundles.

Yes — Movistar has continuous 5G along the AP-7 Mediterranean motorway from Barcelona south to Valencia and Alicante. Vodafone Spain and Orange match that coverage. Expect LTE in tunnels and brief dead zones in mountainous sections near Tarragona.

Yes — Cabify and Uber both work over the eSIM's data connection. You will get live driver location, fare estimates, and in-app messaging. No local Spanish number required; both apps route communication through the app itself.

Yes — Movistar and Vodafone Spain deliver strong LTE in Granada's city center and around the Alhambra. Granada's CTM bus app needs live data for real-time arrivals and mobile ticket validation. Coverage thins in the Sierra Nevada above the ski resorts.
