If I remember correctly I connected to Vodafone and Orange when in Barcelona.
Just make sure roaming is active on your account.

Thanks Northerner. I ended up calling EE customer services. They told me that you have to manually set up the roaming services and go to mobile networks available. Then you will see some appearing in the screen (in my case Vodaphone, Orange Sp, Yoigo and Movistar). You can tap anyone in order to get the service.
