Just replied to you in the general forum, Steve. I am sure you can get this topped up at the shop in Sabinillas, just up the road from Barclays. If you buy the top up cards you can, with the correct code to input (I believe) put the sim in your mobile and top up that way (scratch card type of top up). That's basically what they will do in the shop in Sabinillas.
Edited to say: Steve, I think you can also top up online through your bank - I know you can with Banco Popular.
