I'm going to Barcelona with a few friends for 5 days, and I'm looking at getting a local SIM card for data and ability to text each other. Orange has the 'Delfin 2' deal, which sounds the sort of thing I want: For €2: 100Mb per week, along with 1 cent per text and 1 cent per minute (plus inital 15 cent call charge). However, Orange detail the data in megabits, so that's really only 12.5MB's. And I'm not sure if I can just pay €2 and use it for the 5 day trip and then let it expire without repercussions. Any Spanish locals want to chime in with alternatives?
