Stay Connected in Spain

Spain's connectivity is generally excellent. You'll find strong 4G and increasingly widespread 5G across major cities like Madrid, Barcelona, Seville, and Valencia. Smaller towns along the Costa del Sol or in Andalusia also tend to have reliable coverage. The patchiness catches travelers off guard once you're hiking in the Pyrenees, exploring rural Extremadura, or driving back roads in Galicia, where signal drops for stretches. Worth knowing before you buy anything: Spain is part of the EU 'Roam Like at Home' zone, so European visitors usually pay nothing extra. Public WiFi is everywhere, from cafes in Granada to AVE high-speed trains. Quality varies wildly. The frustrating bit? Some budget hotels still cap WiFi at painfully slow speeds, and Spanish bureaucracy means buying a local SIM involves passport registration that can eat into your first afternoon.

Three main carriers matter in Spain: Movistar (owned by Telefónica), Vodafone Spain, and Orange. Movistar tends to have the broadest rural coverage, mainly in northern Spain and the Balearic Islands, and is generally considered the most reliable for driving routes through Castilla-La Mancha or Asturias. Vodafone Spain is competitive in urban areas with strong 5G rollout in Madrid and Barcelona, often clocking download speeds of 200-400 Mbps in city centres. Orange offers solid value and decent coverage, popular with budget-conscious users. Yoigo deserves a mention too. It's a smaller carrier that piggybacks on Movistar's network and frequently undercuts the big three on price. As of now, 5G is widely available in cities and most provincial capitals, with 4G LTE blanketing the rest of mainland Spain. The Canary Islands and Balearics have good coverage near tourist hubs, though it thins out on smaller islands like La Gomera or Formentera.

Public WiFi is everywhere in Spain, from cafes in the Albaicín to airport lounges and AVE trains, and most of it is unsecured. Hotel networks are a weak spot. Everyone on the same network can potentially see unencrypted traffic, and Spain's tourist-heavy cities make hotel WiFi an attractive target for opportunistic snooping. Travelers tend to be targets because they're often logging into banking apps, booking sites, or work email on networks they don't control. A VPN like NordVPN encrypts your connection between your device and the wider internet, which means even if someone is watching the WiFi traffic at your Barcelona hotel or that lovely cafe in Valencia, they see scrambled data rather than your passwords. Worth installing before you travel. You'll probably use it more than expected.
