Notes ATS0=000 will disable auto answer for
GSM. If AT+CGAUTO is = to 2 or 3
(default), the MT shall attempt to perform a
GPRS attach if it is not already attached,
when the 'S0=n' (n>0) command is
received.
With default settings, if ATS0=(>0) is
sent immediately after power up, an
error will be returned because the MT
will attempt to do an attach before the
AT+CREG state has changed to 1.
