The group of commands has global parameter '--debug' which means 'Increase logging verbosity to show all debug logs.'. The group of commands has global parameter '--help -h' which means 'Show this help message and exit.'. The group of commands has global parameter '--only-show-errors' which means 'Only show errors, suppressing warnings.'.

You can configure the default subscription using `az account set -s NAME_OR_ID`.'. The group of commands has global parameter '--verbose' which means 'Increase logging verbosity. Use --debug for full debug logs.'. This group contains a child command 'az_mobile network_sim_group_bulk upload sims'.The syntax is: az mobile-network sim group bulk-upload-sims --sims
                                             [--ids]

                                             [--subscription]. The 1th example of the child command would be to use it to 'uploading multiple sims to a sim group', the syntax is: az mobile-network sim group bulk-upload-sims -g rg --sim-group-name SimGroup --sims "[{name:bulk-upload-sim-01,authentication-key:00000000000000000000000000000000,operator-key-code:00000000000000000000000000000000,international-msi:0000000000},{name:bulk-upload-sim-02,authentication-key:00000000000000000000000000000001,operator-key-code:00000000000000000000000000000001,international-msi:0000000001}]"
az mobile-network sim group bulk-upload-sims -g rg --sim-group-name SimGroup --sims "[{name:bulk-upload-sim-01,authentication-key:00000000000000000000000000000000,operator-key-code:00000000000000000000000000000000,international-msi:0000000000,icc-id:00000000000000000000,device-type:camera,sim-policy:{id:/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg/providers/Microsoft.MobileNetwork/mobileNetworks/mobile-network/simPolicies/policy01},static-ip-configuration:[{attached-data-network:{id:/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg/providers/Microsoft.MobileNetwork/packetCoreControlPlanes/pccp01/packetCoreDataPlanes/pccp01/attachedDataNetworks/internet1},slice:{id:/subscriptions/00000000-0000-0000-0000-000000000000/resourceGroups/rg/providers/Microsoft.MobileNetwork/mobileNetworks/mobile-network/slices/slice01},static-ip:{ipv4-address:2.4.0.10}}]}]". The parameter '--sims' is required. It is used to a list of sims to upload.  support shorthand-syntax, json-file and yaml-file. try "??" to show more.. The parameter '--ids' is optional. one or more resource ids (space-delimited). it should be a complete resource id containing all information of 'resource id' arguments. you should provide either --ids or other 'resource id' arguments.. The parameter '--no-wait' is optional. do not wait for the long-running operation to finish.. The parameter '--resource-group -g' is optional. name of resource group. you can configure the default group using `az configure --defaults group=<name>`.. The parameter '--sim-group-name' is optional. the name of the sim group.. The parameter '--subscription' is optional. name or id of subscription. you can configure the default subscription using `az account set -s name_or_id`..
