Hello.
After updating firmware in Dell 5809e to latest via qmi-firmware-update my modem gets locked (sim-pin2 is enabled). Any idea how to revert that?
Are you 100% sure you were not seeing SIM PIN 2 lock before the firmware update as well?, because that is quite strange? Anyway, please note that the modem can be used normally for connection and such and only some side-features (e.g. fixed dialing) are blocked by SIM PIN 2.
I’ve updated via this two files:
SWI9X15C_05.05.78.00.cwe and SWI9X15C_05.05.78.00_Generic_005.029_000.nvu
After that modem stopped working in Windows and Linux.
I saw sim-pin2 enabled in mmcli Status section and in 3GPP section there was enabled locks: fixed-dialing, sim-pin2 - there was no operator data at all.
I updated using this files multiple times and it was not working.
Updated once again using 9999999_9902674_SWI9X15C_05.05.78.00_00_GENEU-4G_005.029_000-field.spk and now I have something like this:

So now I’m able to connect via Linux and Windows OS without any issues, but still I’m not sure what fixed-dialing and sim-pin2 means. I didn’t enabled any sim pins at all.
Does this mean I have simlock in my modem? It was not having simlock for sure. I don’t have any other operator simcard to check.
Maybe updating firmware with card in it is locking modem to specific operator?
Maybe fixed-dialing means I’m only able to connect to Orange cause it’s Orange operator sim card?
No idea 
I see no issue in that mmcli output, truth be told, all is fine.
The sim-pin2 lock, as said, doesn’t prevent you from connecting the modem, it just gives access to update the fixed-dialing list (e.g. if you want to restrict calls to specific numbers only and such). That lock is not a carrier/network lock, btw, your modem isn’t locked to a specific operator.
Thank you for explanation. This one is good mmcli output, I don’t have previous one, but as I said, there was no such line like :
| operator id: 26003
| operator name: Orange
| registration: home
And status was something like this
-----------------------------
Status | unlock retries: sim-pin2 (3)
| state: enabled
| power state on
