Normal shutdown after sending the AT^SMSO command. Only a voltage regulator is active
for powering the RTC. Software is not active. Interfaces are not accessible. Operating volt-
age (connected to BATT+) remains applied.

Airplane mode shuts down the radio part of the module, causes the module to log off from
the CDMA network and disables all AT commands whose execution requires a radio con-
nection.
Airplane mode can be controlled by AT command (see [1]).
