Hi Danny, this can be done in the app version of Careers360. Please download the app and login. In the home page there will be a small three parallel lines symbol at the top left. Click on it and your name and other particulars will get displayed. Click on your name and it will redirect to the other page. Now you can see three dots on the top right corner of the new page. Click on it and you will get a pop up in that click "My Profile". On click on it. You can see an option "Change number" and click it to get the number changed.
