Shortened standby time.

The duration of standby time
is affected by your service
provider’s system configuration.
The same tablet used with
different service providers'
systems does not have the
same duration of standby time
(LTE/HSPA+ only).

If you are located in an
area where the network
signal is weak, move
your location to the area
where the network signal
is strong or temporarily
turn off your tablet if
needed.

If you are not able to connect
to the network, the tablet
continues to send out signals
as it attempts to locate a
base station. Doing this
consumes battery charge and
consequently shortens standby
time.

Change your location to
one where the network is
accessible, or temporary
turn off your tablet or set
it to airplane mode.

Messaging problem

Unable to send or
receive text messages.

Your tablet is in airplane mode
with no wireless connectivity.

Slide the status panel
down and then disable
AIRPLANE MODE.

The network signal strength is
not strong enough.

Try moving to a different
location for better signal
reception.
