Optimizing the Communication
Settings
The “

” (Optimizing the communication
settings) software is a “TCP parameter setting” tool that
makes optimal use of TCP/IP transmission capabilities
for packet communication on the FOMA network. To
make the most of the communication performance
of the FOMA terminal, you need to configure the
communication settings using this software.
To connect to a PC overseas, you need to cancel the “

then do it.
