Sometimes a modem will be swapped while re-using the original SIM card from the unit. In this case, the new modem will come without a SIM card in it.

Re-using the SIM card does not work in all cases, only re-use SIM in a new modem if instructed by EMIT.

=== DCT ===
Unplug the plugs from the back of the DCT and remove back DCT cover (4 corner screws). The DCT can remain in the panel.

Locate the modem in the upper-left corner.
