A: Module Customization

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 representative sample of

available customizations—all AT commands can be used for customizations

depending on carrier requirements.

Note: Contact your Sierra

Wireless account repre-

sentative to get the

password.

(Prepare the modem for customization)

1. Unlock the command to use extended commands:

AT!ENTERCND=”<password>” (page 28)

2. Put the modem into offline mode to perform customizations:

AT!DAOFFLINE (page 109)

3. Back up the modem’s RF calibration data as a precaution:

AT!NVBACKUP=0 (See UMTS Modems Supported AT Command

Reference, Document 2130617)

(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=<pid>,0 (page 74)

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 UMTS Modems Supported

AT Command Reference, Document 2130617)

c. Initialize the primary and secondary DNS addresses:

AT!SCDNS=<pid>,”0.0.0.0”,”0.0.0.0” (See UMTS Modems

Supported AT Command Reference, Document 2130617)

d. Clear PDP-IP connection authentication parameters:

AT$QCPDPP=<pid> (page 89)

Note: Make sure a SIM is

inserted in the module

before using the

+CGTFT

command.

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)

g. Mark the minimum acceptable Quality of Service profile as

undefined:

AT+CGQMIN=<pid> (See 3GPP TS 27.007)
