Various modem features can be customized to meet individual
carrier or oem needs.
The following procedure describes how to prepare the modem
for customization, maintain profiles, and customize various
features.
Note: Some customizations described in this section may only be
available on specific modules (for example, GPS customizations) or
for specific minimum firmware versions. Also, this is only a represen-
tative sample of available customizations—all AT commands can be
used for customizations depending on carrier requirements.
(Prepare the modem for customization)
1. Unlock the command to use extended commands:
AT!ENTERCND="<password>" (page 27)
2. Put the modem into offline mode to perform customizations:
AT!DAOFFLINE (page 70)
3. Back up the modem's RF calibration data as a precaution:
AT!NVBACKUP=0 (See Supported AT reference)
(Maintain Profiles)
4. If the modem was provisioned with profiles that you do not
want to keep, you can remove them. To remove (clear) a
profile (profile number <pid>):
a. Mark the profile as non write‐protected:
AT!SCROPROF=0,<pid> (page 53)
b. Set the profile for manual activation, don't prompt for
password, don't auto‐launch application, and disable the
PDP linger timer:
AT!SCPROF=<pid>,"",0,0,0,0 (See Supported AT
reference)
c. Initialize the primary and secondary DNS addresses:
AT!SCDNS=<pid>,"0.0.0.0","0.0.0.0" (See Supported AT
reference)
d. Clear PDP‐IP connection authentication parameters:
AT$QCPDPP=<pid> (page 59)
e. Set all packet filters in the Traffic Flow Template as
undefined:
AT+CGTFT=<pid> (See 3GPP TS 27.007)
f. Mark this Quality of Service Profile as undefined:
AT+CGQREQ=<pid> (See 3GPP TS 27.007)
