If there is an existing 3G modem in the 4200x console, you will need to remove the existing modem and cancel service. Then plug in the new 4G LTE cellular modem(PERS-LTET-4200X or PERS-LTEA-4200X). For details, see image below.
If this is a new 4200x console, just plug in the new modem. For details, see image below.
