SIM mapping
A Public Land Mobile Network (PLMN) is a combination of wireless communication services offered by a specific operator in a specific country. A PLMN is identified by a globally unique PLMN code, which consists of a Mobile Country Code (MCC) and a Mobile Network Code (MNC).
FortiExtender uses a PLMN list to identify the carrier of the SIM cards you are using.
You can also use the following commands to add customized entries to the PLMN list to support the SIMs of unlisted carriers, or create a new PLMN list of any listed carrier:
# config lte simmap
(simmap) # edit vzw-222-33
(vzw-222-33) <M> # set mcc 222
(vzw-222-33) <M> # set mnc 333
(vzw-222-33) <M> # next
(simmap) # end
|
FortiExtender automatically switches its modem firmware based on the carrier and technology you are using. If the carrier can’t be identified or is unlisted, the generic firmware is used. The generic firmware works with most carriers. To help FortiExtender recognize the correct carrier name, you can add the MCC and MNC to the configuration file, but this isn’t required normally. |
