Temporarily using a mobilephone in Spain

I´m coming from Scandinavia and will be staying in Spain/Madrid for a few weeks.
Does anybody know if the spanish mobileoperators offer solutions (cards) by which one could use temporarily one´s mobilephone through a local spanish operator.

Thanks,
Zep

Hi Zep,
I looked into international phones, and you can rent a phone for about $1.49 a day, and then pay for each minute you talk. I found mine through Verizon Wireless, but you can search "International Cell Phones" on the Internet, and find ones to rent there.
Hope that helps.
