Yes, it is possible to migrate an existing WhatsApp Business API line to another WhatsApp provider (BSP/ISV).
To carry out the migration, it is necessary that the Callbell team sends a solicitation to our current BSP to free the WhatsApp line, deactivating the authentication of the two factors that bind the line to Callbell (2FA) or by doing a downgrade.
The cost of managing this by part of the Callbell team is 299 EUR (single payment)*.
Once the payment has been made, the customer must fill in the following form to proceed with the release of the API line: https://callbell.typeform.com/to/axw6pnmb
