Hum... the modem doesn't seem to reply to any command. How are you
connecting the modem to the RPi? Are you using an external *powered*
USB hub? Or just plugging it in one of the USB ports of the RPi? Note
that the RPi has a max output power in the USB ports, and likely the
modem won't work unless you use a external powered USB hub.
