PLEASE NOTE: To change the phone number, you need to create a new WABA. This means you will lose all account details/data, insights, OBA & tier from your actual WhatsApp Business Account. Before switching numbers, we advise you to communicate the change to your subscribers.
How-to:
Connect your new number by following the steps in the guide
Request WhatsApp account validation from charles (as your WhatsApp service provider, we need to validate the creation of your WhatsApp account before you will be able to use it.) Please request the validation via the chat bubble in the universe.
The charles team will then delete the previous phone number from charles.
