Currently (since November 2016) it's not recommended to use an email account from orange.fr. It's quite likely that you won't receive the email containing the unlock information right after your purchase with an address from this provider. orange.fr blocks emails coming from the mail server network used by klangfreund.com. This mail server network is a very trustworthy one, also used by Twitter, PayPal and other big companies.
