That's right!
It's available for postpaid customers only.
It seems that sending and receiving emails with a prepaid card is free: "Réception gratuite et illimitée de vos e-mails de votre messagerie Internet directement sur votre mobile en France métropolitaine."
You just have to set up your iPhone to do so: http://www.entraide.bouyguestelecom....n_resolue/5379
