Best eSIM for Spain Spain is one of the easiest countries in Europe to travel through. The roads are excellent, trains connect most major cities, and navigating between regions is straightforward. But staying connected matters more than people expect. Maps, parking apps, train tickets, restaurant bookings, translation tools, remote work calls; almost every daily travel task depends on reliable mobile data. When I road-tripped across Spain for two months with my dog Roly, connectivity was something I barely had to think about. My setup was simple: a SIM-only plan with EE from the UK, which includes EU roaming and unlimited data. That meant my phone worked exactly the same across Spain as it did back home in London. No airport SIM cards No roaming surprises No switching networks Google Maps worked instantly navigating cities like Barcelona and Madrid. Parking apps, restaurant bookings, train tickets and work calls all functioned normally. For UK travellers with EU roaming plans, that setup often works perfectly. But if your carrier charges roaming fees or you’re travelling from outside Europe, an eSIM is usually the easiest way to stay connected in Spain. This guide breaks down the best eSIMs for Spain, how they compare, and which options make the most sense depending on how you travel.
