Hi St Carles is poor reception for net as a whole we had boat there and the marina spent a fortune trying to sort it out turned out was just bad area, however we used a vodaphone mobile dongle and found it as good as anything .Hope this helps.

Hello, you could try onanet. They are based in Vinaros but cover St Carles. They use radio (Wimax) to distribute the internet.
It is what I use but from a different company in Vinaros. The company I use does not cover St Carles
