Could someone please let me know what documentation ( ID, address, etc.) is
required to buy a pre-paid SIM from Orange or another mobile phone company
in France for a 1-month stay.
prepaidgsm.net  does not provide this information, at least not where I
could find it. I have not had any troubles in Austria, Germany, and Italy,
but ...
I trust that this is cheaper than buying such a prepaid SIM from one of
several providers on the web before my departure.

TIA

Franz
