Hello Ajay
In the vast majority of 4G Verizon installations the APN is already
programmed into the modem from the factory, in a unique case where you have
requested from Verizon “mobile terminated data” and Verizon assigns a public
static IP Address, the modem will download the custom APN from the Verizon
network upon registration. In situations where a custom APN needs to be
programmed into the modem, you would create a case in out Support Portal to
get that procedure.
