The credit on ex-B&You Simyo SIM cards is valid for 365 days since the last balance deduction.

if you bought the card on b&you during the initial offer, the name is simyo but the contract with the same core conditions as b&you remains. period.

As a newcomer to the world of overseas pre-paid deals, I’ve just read the entire B&YOU thread from top to bottom and it’s like a thrilling switchback ride with all its ups and downs! So from what I understand, the original B&YOU offer has closed; but what is the feeling about its successor from SIMYO? Is the latter considered a good (the best?) pre-paid deal for calls and data in France?
Many thanks in advance for comments.

New name "Carte prépayée Bouygues Telecom", no core change in expiration

I WAIT CONFIRMATION THE 26TH AUGUST.

I've just received the following e-mail from Simyo:

Bonjour ,

Le 12 novembre prochain, Bouygues Telecom cessera définitivement d'exploiter la marque simyo.
A cette occasion, dès le 26 août, votre offre prépayée sera rebaptisée « Carte Prépayée Bouygues Telecom », et vous aurez accès à l'espace client Bouygues Telecom.

Pas d'autres changements pour vous : vous conserverez votre ligne, vos recharges sans durée de validité et la possibilité de recharger dans votre point de vente habituel, par téléphone ou par internet.

Rendez-vous dans l'espace client simyo.fr pour en savoir plus.

L'équipe simyo.

Maybe using the Bouygues website will be better. I live in the US and It would be great if I could use a non-French credit card to recharge. I'm not familiar with the Bouygues website, so I don't know how it will work out.

Thanks for asking us to the change!

new official name "Carte Prépayée Bouygues Telecom sans durée de validité"
so no core change....
