Hi Michele,

If you wind up not being able to get a SIM before you leave, and if you find it difficult to find one at CDG--it is a very spread out airport and services are not evenly distributed it always seems to me--I'd just buy a normal phone card (for use in a pay phone) for the call to your rental agency, then pick the SIM up in town. My guess is that you'll use up all your minutes on that card as well as your SIM before you're done with your vacation. A phone card ought to be findable at any of the newsstands. (Mind you, it's possible you could find your SIM there, too, though that's more variable. Worth asking, though.)

Have a nice trip.
