Indicator light
If the indicator light is red, the
device cannot register to a cellular
network because the SIM card is not
valid or properly inserted or cannot
find a supported network in your
location. If the red light flashes, the
device is not registered to a cellular
network because you have not
entered the PIN code, if the PIN
code request is enabled in the Nokia
Internet Modem application.
If the indicator light is green, the
device is registered to a GSM
network and transferring data. If the
green light flashes, the device is
registered to a GSM network, but
the data connection is not active.
