WWLAN card EM7455 Not Working - Thinkpad X260

I have a Thinkpad X260 and a Sierra Wirless AirPrime WWLAN card.  When the card is installed the system fails to boot an Operating system throwing an error: 1802: Unauthorized network card is plugged in - Power off and remove the network card.  System is halted.

 

The Box for the WWLAN card has Lenovo's Tape Seal, and a Lenovo FRU label/number.  The compatibility matrix says this card is compatible.  Please help.

 

Notebook Details:

 * UEFI BIOS Version: R02ET50W (1.23)

 * Embedded Controller vserion R02HT29W (1.11)

 * Machine Type Model: 20F6CT01WW

 

WWLAN Details:

 * FRU P/N: 00JT542

 * Model: EM7455

Hello and welcome

What IDs values (2x4 symbols via slash) are shown on the screen with error 1802? Could you provide the photo of your wwan card label?

I did a "reset factory defaults" without the OS Optimizations in the bios, and this corrected the problem.
