We are attempting to attach a UE to a private 5G deployment and the UE uses the EM9291 modem. Output from qmicli suggests the SIM is ‘illegal’, but this SIM has been used to successfully connect other UEs to the same network.
voxl2:/$ qmicli -d /dev/cdc-wdm0 --uim-get-card-status
[/dev/cdc-wdm0] Successfully got card status
