Sosh is contract only, so unless you have a French bank account and sign up for a monthly contract, that won't be an option. Same thing for B&You's plans with the exception of their new
prepaid card offer at 4.99€ for the SIM including 15 minutes, with recharges available in varying amounts. The downside with that is there's not much data offered, the SIM will be mailed to a French address, and I'm not sure whether a foreign credit card can be used for the online purchase.
This is now two different threads on two different forums where
iff has stepped in with the right data. Merci beaucoup. ^
If anyone has any doubts that you will not be able to use Sosh, here is
what they require to open an account:
Les informations dont vous aurez besoin lors de votre commande :
- Un justificatif d’identité en cours de validité
- Un relevé d’identité bancaire
- Une carte bancaire s’il s’agit de votre mode de paiement
- Un n° de téléphone valide pour pouvoir vous joindre en cas de besoin
- Une adresse mail qui nous permettra entre autres de vous parvenir le mail de confirmation de commande.
Putting this through Google Translate will not give you a clue of how much red tape this really is. The second item, for example, in reality means "proof of a French bank account for debit purposes." In other words, your Citibank ATM card will not do.
