Summer 2018 I was traveling to Paris a couple times and looked into buying a sim card in Paris. Just last weekend (February 2019) I visited Paris again and double checked the prices for sim cards at Paris Airport for you. Again I was surprised that buying a prepaid sim card in France is not as expensive as in other European countries like Germany and Netherlands. In the city center of Paris there are actually a couple European sim card options for tourists available, but I was also curious about buying a sim card at Paris Airport.
