How do I synchronize my phonebook with my Onoff account?

From the home screen, open the menu via the icon on the top left.

Go to "My account" then "Application settings" and activate "Contacts synchronization".

You will first have to authorize the Onoff Business application to access your phone book on your phone

This option will copy all your contacts from your phone, and you will find them on your Onoff Business application.

In case you change your phone, your contacts will remain on your Onoff Business account. You will only have to install the application, to find your contacts and phone numbers.
