Q2406b Restart

Hi,
i would like to know if there is any way to remotely restart the modem. Can we send
AT commands by sms? the modem is installed in a specific product that is not easy to
access and the modem is hung. It maybe needs a restart by AT+CFUN=1 or a reset but
if it was possible to do this remotely it would be great.

Thanks.

Not without an Open-AT application within the unit.
