information about dongle dc-unlocker full act


I bought the DC-unlocker dongle with a ticket "full act"
it needs annual activation as the other or not?
I activated dc-phoenix malgrés credits with the dongle is "full act"
is that the dc-unlocker dongle also has to pay the FRP unlimited option?
if yes
what is the difference between the dc-unlocker dongle and dc-unlocker activated on another third party?
with this huge price difference between the price dongle or activation of infinity or rocker
