Help using Verizon on my Lte modem

Hello

I am a telecom guy and used to do a good bit of work with Verizon during the great days of 2/3g 1X/CDMA EVDO.

During that time, the way the VzW network worked was , on the equipment side,

vendors built equipment which was approved by Verizon for their network (phones modems routers etc)

The vendors would create a list of these devices with an ID that related to the equipment.

If you look at the device you may see an ESN (electronic serial number) or MEID (mobile electronic equipment ID) for 2/3g devices

IMEIs (internaltion mobile equipment ID) for 4G devices and

ICCID for 4G sims

These are uploaded on a Verizon device management Database

When a customer bought a device, they would scan the SIM and then the hardware and associate the two to you

THis would prevent customers from swapping sims around or using unapproved hardware on their network.

This was they way it worked as far as I recall some years back. Given your brief description, sounds like that is still the case and may be the reason you are seeing the error.

You could try swapping the sim to other devices to see if that sim is locked to one particular device
