Data communication
The data communication and connection modes
available from FOMA terminal and hints on use
are explained.
･
FOMA terminal does not support fax communication.
･
When connecting FOMA terminal to DoCoMo’s
PDA “Sigmarion
Ⅱ
” or “musea” for data
communication, make sure to update “Sigmarion
Ⅱ
” or “musea”. For details on update such as
method, visit the DoCoMo Web site.
Supported communication modes
FOMA terminal supports three communication
formats: packet communication, 64K data
communication and data transfer.
Packet communication charges are based on the
amount of data sent and received, which makes it
suitable for high-speed exchange of comparatively
small amounts of data as in sending and receiving mail.
No communication charges are required when no data
are exchanged even if you are connected to the
network. Therefore, sending/receiving data as needed
while remaining connected to the network is possible.
High-speed packet communication provides a
maximum reception speed of 384kbps and a
maximum transmission speed of 64kbps by using
access points that support packet communication on
FOMA, such as DoCoMo’s mopera Internet
connection service. Best-effort connection which
allows the transmission speed to vary with the
enviroment and the rate of congestion.
This type of communication becomes available by
installing the related software on a PC from the CD-
ROM provided, connecting FOMA terminal to the PC
and making required settings.
Note that communications of large-size data such as
viewing Web pages containing images and
downloading will require high charges.
The 64K data communications allow data
transmission/reception at stabled communication rate
of 64kbps. Communication charges are based on the
duration of the connection to the network regardless
of the volume of data, which makes it suitable for
sending and receiving relatively large amounts of data
as in downloading multi-media contents. Use access
points that support FOMA 64K data communication
services such as DoCoMo’s mopera Internet
connection service or ISDN synchronized 64kbps
access points.
This type of communication becomes available by
installing the related software on a PC from the CD-
ROM provided, connecting FOMA terminal to the PC
and making required settings.
Data transfer is a form of non-charged
communication in which data are transferred/
exchanged via following connection methods.
Various data including the phonebook, incoming/
outgoing mail and bookmarks are sent /received.
Data transfer can be used by connecting a FOMA
terminal with another FOMA terminal, mobile phone
or PC terminal. Before exchanging data with a PC,
install the related software on the PC from the CD-
ROM provided.
Connecting FOMA terminal to other devices
Two types of connection are available. Infrared
communication can be used only for data transfer.
You can connect FOMA terminal to a PC equipped
with a USB port using a FOMA USB connection
cable (optional).

･
Installation of the communication configuration file
on a PC is needed before making the connection.
You can send or receive data by using infrared to
connect a FOMA terminal to another FOMA terminal,
mobile phone, PC or other device with an infrared
communication function.

Usage precautions
When using the Internet from PC, usage charge to
your Internet service provider (herein after called as
provider) is generally required. This charge is paid
directly to the provider, and is separate from the
FOMA service charge. For more information on
usage charges, contact your provider.
･
DoCoMo Internet connection service mopera
allows you to access the Internet without
subscription to the service. Also, no monthly fee is
required. If you would like to make a connection
with Internet easily, it is recommended to use
mopera.
