Make sure that the LTE module is physically connected to the USB port of Abilis.

Check if the LTE-BOX is recognised by Abilis as a USB device (Android):

Verify if the LTE-BOX is recognised by Abilis as a active USB device:

The Cellkey device must be Run:Yes and Con:Yes. If Run:No, this means what after adding of device Cellkey, the Abilis was not restarted. If Con:No, the possible cause may be the USB port mismatch. In this case check if the value of the USPORTID parameter it is identical, configured/assigned in d dev and seen with d usbdev.

The usbportid can't change on-the-fly plugging and unplugging a device on a different port. If connecting a device on a different port is needed, follow the below steps to reconfigure the USBPORTID parameter:

[12:48:39] ABILIS_CPX:s dev:cellkey-1 usbportid:none

COMMAND EXECUTED 

[12:48:44] ABILIS_CPX:init usbdev

If error is present in CELL-ERR it is possible to restart the LTE-BOX, it often helps:
