Porting my number to Onoff

You can import a French number into the Onoff application.
This number will then become an Onoff number.
As a reminder, an Onoff number is a secondary line, used in addition to your main line.

⚠ ATTENTION: Number portability entails termination of your operator contract.
If you only have one line, you must not port it to Onoff.
In fact, you must have a physical line in your mobile in order to use an Onoff number.

To port your number to the Onoff application, contact the operator of the line you wish to import, or call 3179 to obtain the RIO code (unique code attached to your line, essential for portability).
- In the application, from the home screen, open the left-hand pane via the side menu ☰ top left and select "add a number"
- Press "Keep existing number"
- Let us guide you to start the migration process.

The portability process takes 5 working days, but you can choose a later date.

Once ported to the application, you can activate your number by taking out a subscription (see pricing conditions on our website https://www.onoff.app/fr/offres/ ).

Your Onoff number will operate on your main line's GSM and/or Data networks.

We hope you enjoy using it!
