This error occurs when the phone number associated with your WhatsApp Business account has been deleted in the Meta Business Suite. To resolve this:

*   Add a new phone number to your WhatsApp Business account in the Meta Business Suite.
*   Then, [update the WhatsApp Business account](/billing/help/integrations/whatsapp/whatsapp-integration.html#Change-Default-WhatsApp-Number) in your Zoho Billing organization with the new phone number.

You can then send WhatsApp messages to your customers without any interruptions.
