Sim Card; Built-In Storage; Adding Storage - Barnes & Noble nook User Manual

As you press the edges together, you will hear snapping sounds as the hooks snap into
place.
5 Look around the edges of the nook to see that the back cover is securely attached. If the
back cover is not securely attached, press edges together that did not seat correctly. If that
does not work, remove the back and repeat this procedure.

SIM Card

The AT&T SIM card in your nook is pre-installed and permanent. It is used when the nook
connects to the online Barnes & Noble store and nook data services over the AT&T cellular
network. You will never need to remove or change the SIM card. Specifically, please note the
following about the SIM card:
 You cannot use the nook SIM card in a different mobile device, for example, a mobile
phone.
You cannot use a different AT&T SIM card, for example, from a mobile phone, or a SIM

card from a different carrier, in the nook.
 The SIM card in your nook is associated with your nook, whether registered or not. Do
not swap SIM cards between nooks. There is no reason too, and afterwards they will not
be able to connect to the cellular network.

Built-in Storage

Your nook has 2 GB of built-in flash memory. Of this, about 1.75 GB is available for storage of
your eContent. This is enough storage space for about 1500 eBooks or 300 ePeriodical issues.
ePeriodicals tend to be larger because they have more graphical content.
The storage capacity for eBooks and other eContent will be affected by how many
personal files (for example, music files) you download onto your nook.

Adding Storage

If you want to increase the storage capacity of your nook, you can purchase and insert a
MicroSD or microSDHC card.
