Look up above at the prepaid sticky. Look for France, and it should give you some useful information. I have stopped using international sims many years ago. I have a UK sim that I use all over Europe. When I go to the Middle East I usually get a local sim. I have T-mobile but I rather not pay 20cents for a call when I can get incoming free. International sims have been less relevant since the EU has done away with roaming, and so much more expensive than a local sim card.
