AT commands are used to specify and modify the functions of the FOMA terminal through the personal
computer.

The following abbreviations are used in the AT command list:
[AT]: Commands which are available at the FOMA P04B Command Port.
[M]: Commands which are available in the FOMA P04B (modem).
[&F]: Commands whose settings are initialized by the AT&F command.
[&W]: Commands whose settings are saved by the AT&W command. The set value can be recalled by the

Saving the setting contents
Please be careful that the setting contents with AT commands are initialized when the FOMA terminal is turned off and on or the external
device is removed, except for the access point name (APN) setting with the AT+CGDCONT command, QoS setting with the
AT+CGEQMIN or AT+CGEQREQ command, incoming call acceptance/rejection setting with the AT
¢
DGAPL, AT
¢
DGARL, or
AT
¢
DGANSM command, phone number notification/no notification setting (for packet communication) with the AT
¢
DGPIR command
and caller ID notification restriction setting with the AT+CLIR command. For commands with [&W], you can enter “AT&W
” (after
setting) to save the setting contents and other set values with [&W] at the same time. If necessary, you can restore these set values by
entering in “ATZ
” even after the power is turned off and on.
