    This means your number is still connected to another WhatsApp Business API platform. (Wati, Respond.io, Trengo, etc.)

    Step 1: disconnect from the current platform

    1
  1. Log into your current WhatsApp platform (e.g., Wati)
    2. 2
  2. Go to their WhatsApp settings
    3. 3
  3. Disconnect or deregister the phone number.
    4. 4
  4. Important. Confirm the number is fully deregistered. Some platforms have a "disconnect" that doesn't fully release the number.

    5. Step 2: wait for the number to be released

    After disconnecting, wait 5-10 minutes for Meta to release the number from the old platform.

    Step 3: onboard

    Meta's changelog entry of 3 September 2026 puts the phone number first in Embedded Signup, before the business portfolio and WhatsApp Business account. Meta states that the rollout is in progress, so some businesses still see the business portfolio screen first.

    1
  5. Go to Settings > Channels > Add Channel > WhatsApp
    6. 2
  6. Follow the Embedded Signup flow and sign in with your Facebook or Meta Business Suite account
    7. 3
  7. Enter or select your phone number
    8. 4
  8. Verify the number with the code Meta sends by text message or phone call
    9. 5
  9. Select or create your business portfolio and WhatsApp Business account
    10. 6
  10. Complete the setup

    11. Several Voltade customers have migrated from Wati. Key notes:

    • Message history won't transfer automatically. Wati doesn't provide an API export. History migration requires manual steps (QR code scanning, tampermonkey script export). Contact support if you need history preserved.
    • Templates need to be recreated. Your Wati templates won't carry over. Create new templates in Voltade or via Meta WhatsApp Manager.
    • Contacts transfer via CSV. Export your contact list from Wati and import into Voltade.
    • Automations and AI agent flows need to be rebuilt manually in Voltade. Screenshot your Wati flows before disconnecting.

    The previous platform may not have fully released the number. Contact the old platform's support to confirm deregistration, or wait 24 hours and try again.
