There are no telco shops at the BCN airports (or you'll need to look for them for ages in the mall). But there is free WiFi in the airport and the downtown is a 20 min train ride away. I know this is different to Australia where you can find Telstra, Optus and Vodafone outlets at most airports.

Better go downtown to Barcelona (or any other town or shopping mall). You can easily spot the same Vodafone logo as in Oz, plus many Orange and Movistar stores. There are smaller providers too, but they are harder to find.

In Spain you need to show your passport at the point of purchase. There is no online registration like in Australia. The SIM works immediately after you've been registered at the point of purchase.

If you stay there for more than 30 days, you will need to top-up and buy another package or plan. But you can downsize for your 10 remaining days. You can top-up in many supermarkets and kiosks all over the country €10 or more. For this you need to have your mobile number, as it's an electronic recharge most of the time.
