Prepaid DATA in Spain

[wco81]

This post on TripAdvisor indicates that the "Orange counter" at El Corte Ingles sells a prepaid microsim for iPad which costs 3.5 Euro a day or 35 Euro a month for "unlimited."

There may be limits but the poster doesn't seem to know. Or maybe she doesn't realize there's throttling after a certain threshold?

As I understand it, the Simyo is one of the best for prepaid data but you can't get it at any shops, you have to order it online?

Carrefour is supposedly one of the best values according to this page:

But they're typically not in historic centers? I'm looking at visiting Sevilla and Granada in February, staying in the historic centers. If they're like the ones in France, the Carrefour stores are always at the edge of big cities?

Any experiences with Yoigo lately, as far as speed, reliability, coverage and how easy it is to buy in shops, especially for foreign visitors?
