DSDevices DSCS9X with LTE module


is there a plan or possibility for implementing a LTE module in the DSDevices DSCS9X?
A SIM card slot is already there.

Thank you,

It is actually a MicroSD slot. For restoring Android firmware (if you don’t have the USB-A cable)

Okay, thanks for the new information. Maybe I should check the manual. :face_with_hand_over_mouth:
Never the less, is there a plan for a LTE variant?
