Create wireless profiles
A wireless profile contains detailed LTE modem data session settings. Each modem can store up to 16 wireless profiles.
Any data connection is initiated using the settings from one of the stored wireless profiles. To make a data connection,
you must have at least one wireless profile defined. The following is a sample wireless profile table stored in the internal
modem.

ID Type Name APN PDP_Type Authen Username
1 0 broadband 3 0
Profile Type:
0 ==> QMI_WDS_PROFILE_TYPE_3GPP
1 ==> QMI_WDS_PROFILE_TYPE_3GPP2
* ==> Default 3GPP profile, # ==> Default 3GPP2 profile
Profile PDP type:
0 ==> QMI_WDS_PDP_TYPE_IPV4
1 ==> QMI_WDS_PDP_TYPE_PPP
2 ==> QMI_WDS_PDP_TYPE_IPV6
3 ==> QMI_WDS_PDP_TYPE_IPV4_OR_IPV6
Authentication:
0 ==> QMI_WDS_AUTHENTICATION_NONE
1 ==> QMI_WDS_AUTHENTICATION_PAP
2 ==> QMI_WDS_AUTHENTICATION_CHAP
3 ==> QMI_WDS_AUTHENTICATION_PAP|QMI_WDS_AUTHENTICATION_CHAP
The above is wireless profile of a modem with Verizon firmware. If the APN can be left empty, it indicates a wildcard
entry; if the username shows empty, it means that no authentication is not configured.
There is a default wireless table that can be retrieved from the modem firmware. You can list, create, delete, or modify
the table with the exec lte-modem wireless-profile command. For generic modem firmware, the modem
has no wireless table entries pre- installed and the LTE daemon will create a default entry to be used.
It seems that the EM75xx modems do not support either the 3GPP2 or the PPP PDP types of
profiles. IPv6 is not supported on this modem yet although you can still specify a profile with
PDP type 2 or 3. However, you cannot initiate IPv6 data connection anyway.
When the modem boots up, it automatically scans the network and gets a list of the available candidates for data
connection. With the default system configuration, FortiOS sends the start network request to the modem, with no
(empty) APN, authentication, or wireless profile entry. Upon receiving the request, the modem scans the wireless profile
table, from top to bottom, to find a matching record and make the data call with the settings in that record.
If the APN field is left empty in the wireless profile, the modem make connections to wireless
networks with any APN.
It is very important to have a properly configured wireless profile because many carriers run private networks along with
their public network. When you have a SIM card for a private network, it can be used to connect to either a public or a
private network. If you define a wireless profile without an APN, then it would make connections to any network it scans.
When it connects to a unwanted network, it will receive no service. Having a clearly defined profile table can prevent this
issue. Assuming that you have a SIM card which can be used for either public network “pn” or private network “prn”, and
