Well not really. Almost all the big companies now include international calls too in the contract.
However for Australian people today while I was googling for a SIM card to buy, I found this website very interesting where they send when you are still in Australia the SIM card that you can put on your phone and activate it when you land in Europe. There are included 72 countries. In addition, they give to you 12GB, 3000 minutes of call in those 71 countries and it is valid only for 30 days. Pretty awesome
The price is very cheap only $49 AUD.
The SIM card is UK so the number will be UK.
Here you can find attached the website:

I hope it can be helpful for everyone will do the Camino.
