In Valencia, but this was around 4 years ago and I had a data plan that was also 3-4 years old because I used wifi almost everywhere. As I was a student back then the only problem was the bus from my home to the university and back.

I was with Hacker Paradise for 3 months through SE Asia and I totally agree. I have screenshots yet-to-tweet comparing the great packages from Thailand with the prices in Spain and it's absolutely ridiculous.
