shows that the signal gsm signal is there so it is not an antenna
problem. Please try to register to network manually with socat. First
stop all processes that access ttySAC0 and then

echo 0 > /sys/devices/platform/neo1973-pm-gsm.0/power_on
echo 1 > /sys/devices/platform/neo1973-pm-gsm.0/power_on
socat - file:/dev/ttySAC0,crtscts,crnl,b115200

and then type (mind your own pin instead of 0000)


and tell us the output. Note that you might want to send those
commands multiple times since calypso will go to sleep very fast and
when it wakes up it won't handle the first command it receives.
