To reactivate your Verizon account, you can use either the Verizon app or the My Verizon online account. For the app, go the the 3-line navigation menu in the upper left corner, tap Devices, choose the number needing reconnection and tap Manage. Tap Reconnect, choose “with the same device,” then tap Reconnect, followed by Confirm. For the online account, go to the Suspend or Reconnect Service, choose the number needing reconnection, choose Next, then Submit. Each of these methods should reconnect your service for the same device.
