Hi,
First of all, please update the firmware to the latest version.
Second, you can use uci commands to import dozens of configurations to your system at once.
If you create a dummy operator listing in the WebUI and then type uci show | grep operctl
You will see something like this:
operctl.@operlist[0]=operlist
operctl.@operlist[0].name='asd'
operctl.@operlist[0].mcc_mnc='98745'
Now you can use the same syntax to either add more listings, or you can add more codes to the same listing like this:
operctl.@operlist[0].mcc_mnc='98745' '11111'
Just use uci add, uci set, uci show commands to import, edit or show the configurations of all sorts and you should be able to do everything quicker.
