A:Answer Yes it was easy to switch service to new ooma device. As far as I can tell, your service is identified by and through your device. They will begin your "new" service on your new device.
You will need to call them for your phone number to be on your new device.
If you have premium service paying monthly fee for call block, your probably going to have less problems than I.
If your like me & do not pay for call block, lol remember how few solicitations you had will your old device. I hope your not flooded with new solicitations again since you have a new ooma device and somehow by chance? The scammers etc. decide to start calling your old phone number again through your new device.
