Hello,
Thank you for contacting us!
We are aware of a need for such functionality, and our RnD team is working on adding it, but as of now, there isn't an exact date I could give you of when this feature will be implemented. As for now, I'd recommend reaching the device WebUI via RMS and checking the status of SIM cards that way. I apologize for any inconvenience caused by this issue.
Let me know if there is anything else I can help with!
Best regards,
DaumantasG
