When you register a new device, Boot-Loader
Download Manager checks whether you are
eligible for free initial access. If yes, you
will see a Get Free Access link on the
My Account->Device Accounts page. Click
it, and you will be given a certain download
allowance for a fixed period of time, depending
on the device terms of use.
Free initial access is connected to the device,
and when you unregister and sell the device to
another user while on free initial access, the
remaining device allowance is transferred to
the new owner.
When the free initial access period is over or
if you use up all download allowance (whichever
occurs first), you will need to
top up your device account.
If you buy a used device, you will get less or
no free initial access.
