For what TV?
Contrary to what some may say we should not have a Samsung TV, the key is to have a model equipped with a card slot and CI + compatible satellite tuner obviously. I insist on the + CI + symbol of Tv little older only compatible with the cards in the format "CI" will not recognize the card. For TV purchased abroad or if you live outside of France, do not forget to make sure your TV is set in its menu as in France (in my case living abroad and for a smart TV Panasonic STW50 series ja'i had to do a complete reset of the TV and set the settings).
