Ligne Bis is a virtual French phone number that allows you to communicate without revealing your actual mobile number. This is particularly useful for posting online advertisements or avoiding sharing your mobile number on the internet. When calls are made to your Ligne Bis number, they are directly forwarded to your mobile device.

Obtaining a Ligne Bis number is a paid service and can be done within minutes through the application. You have two options: a 15-day duration without any subscription or commitment for €2.49, or a monthly subscription that automatically renews for €3.39 per month. The latter option is billed through your iTunes account upon confirmation of purchase and will continue until the automatic renewal is disabled (at least 24 hours before the end of the current period). After purchase, you can manage or disable automatic renewal by going to the Subscriptions section of your iTunes account.
