Moving to Aguilas

We will be moving to Aguilas permanently in the Autumn and I would like to have some information on wi-fi , broadband , etc..

Here in the Uk we have Sky for the TV and BT for wi-fi and cell phones and it works fine . 

I have no idea how it works in Spain , can we get one company for everything ? And we would like to be able to see Tv from other countries , not only Spanish .

can anybody helps us  ?

Thanks 

Carlos
