Planning a trip to Spain and wondering what is the best prepaid SIM card for Spain in 2026? After comparing the latest prepaid SIM card plans, network coverage and real travel usability, my answer is clear: Movistar is the best prepaid SIM card for tourists in Spain.

I travel to Spain several times a year, mostly because I am a huge FC Barcelona fan, but my trips go far beyond Barcelona. Over the years I traveled through Madrid, San Sebastian, Bilbao, Pamplona, La Rioja, Valencia, Alicante, Malaga and all the way down to Gibraltar. I also crossed into France and Portugal by land.
