Living in France -> French Sécu, no ?

Sorry Remy I do not really understand what you are asking me

Sorry

If you're living in France, your needs can be covered by the French health insurance (Sécurité sociale)

Hope you speak French :-)

I dont speak French but thank you very much for your help 

If you work in Switserlqand and live in France, you can choose between the Swiss (private) and the French (public) system. Once you have made the choice however, you can't switch back.

Both have their advantages and disadvantages, which you can find here:

In summary, the French system will probably cost you more (8% of income) to pay into.
With Swiss system will cost you around 350 CHF a month, but there's a franchise to pay (300 CHF per year) + 10% of the costs when you go to the doctor.

If you choose the Swiss system, Progrès Versicherungen should be the cheapest option as a frontalier.
