As above, SFR and Orange are the two main players. Get her to get in touch with each of them and get a quote for a package that suits her. Both will do various packages including local / international calls, internet TV, discounted deals if you also have your mobile with them, etc.
We’re on Orange and they’ve been pretty decent, no major hassles. Pathetic speeds, but we’re right at the end of the line (up a mountain in the Alps!).
Any deal with Orange will include their router, which is pretty easy to set up. With Orange, you can plug a telephone handset into the router and make calls over the net (very cheap!).
