Using the handset
The handset supports LTE, W-CDMA, GSM/GPRS and wireless
LAN systems.
Because the handset relies on radio signals, it cannot be used in
a place with no signal (such as tunnels, underground or in
buildings), in places with a weak signal or outside the LTE
service area or FOMA service area. You may not use the
handset in the upper floors of a building even with no
obstructions in sight. There may also be times when the signal is
strong and you are not moving but the call is interrupted.
Because the handset uses radio waves, it is possible for a third
party to listen in on a conversation. However, since the LTE,
W-CDMA and GSM/GPRS systems automatically apply a private
call feature to every call, a third party that tries to listen in only
hears noise.
The handset converts conversations into a digital signal and
sends it to the other party over the radio. If the signal cannot be
reconverted properly by such as moving to an area with a weak
signal, the voice may not be heard correctly.
Take notes of information (e.g. the phonebook, calendar, note,
voice memo, answering memo) stored on the handset or save
the information to external memory devices such as microSD
Cards and PCs periodically. DOCOMO shall not be liable for any
loss of content due to a failure, repair, model change or other
handling of the handset.
As with PCs, some user-installed apps, -accessed websites, etc.
may disrupt the stability of your handset performance or
unexpectedly transmit information via the Internet causing
improper use of your location information, personal information
stored on the handset, etc. Therefore, verify the supplier and
operating conditions of the apps, websites, etc. to be used before
using them.
The handset supports the FOMA Plus-Area and the FOMA
HIGH-SPEED Area.
When the available space on the microSD Card or the handset is
insufficient, apps in use may not work properly. In this case,
delete saved data.
The handset does not support connection to i-mode website
(program), i-appli, etc.

mopera U and Business mopera Internet.

phone number (own number).
The handset does not support Public Mode (Drive Mode).
Setting the handset to the manner mode does not mute sounds
(camera shutter sound etc.) other than the ringtone, operation
sound, and various notification sounds.
The handset automatically performs communication for some
functions, for example, to synchronize data, check the latest
software version or maintain connection with the server. Also,
making a communication with large-volume data such as
downloading apps or watching videos will lead to higher packet
communication charges. Subscription to Packet Pack/flat-rate
packet communication services is highly recommended.
Even while the Wi-Fi connection is set, packet communication
charges may be incurred depending on the app and service you
use.
Software on the handset can be updated to up-to-date status

occur.

you lose it (>P. 69 "Lock & security").

using a PC to prevent other persons from using Google services
