First of all, it’s important to confirm that your secret phrase is backed up, either manually, digitally or both.

Then, open the xPortal app, click on “Profile” in the upper left corner and you will find the “Settings” button. If you scroll down, at the bottom of the page, there will be an “Unlink this wallet” button.

Click on the button, complete the process, and once done you can import the wallet again and associate your new phone number with it.
