The Bouygues Telecom offer, how does it work?

If your main line operator is Bouygues, you can take advantage of an Onoff promotional offer.

You can find all the details here: https://www.bouyguestelecom.fr/option-mobile/onoff

When you subscribe to the Bouygues Telecom offer, a random number is automatically assigned to you and a special offer applies, with a €4/month package.

If you wish to subscribe to and choose another number, you'll need to do so via the Onoff application and subscribe to a new package, totally separate from the first, at €4.99/month.

For information, it is not possible to apply the Bouygues offer to a ported number or a number already existing in the application.
