Despite being Visible by Verizon, they are different business entities. You'd need to establish an account with Visible just as you would with any other carrier when switching to Visible. If looking to port your existing phone number to Visible, the Verizon account would be canceled on completing the port over. If wanting a new phone number, you'd need to cancel the Verizon account yourself (presumably after activation is completed on Visible assuming you want to maintain Verizon service until that time).
