LEC_MRC_REG_DENIED all times

Hi, I’m trying to connect my device (WP77XX) to RF wireless communication test set (E6621A) using USIM. When I use “cm radio” command, i have response as below,

Power : ON
Current Network Operator: USIM
Current RAT : Module not registered on network, RAT not available
Status : Registration was denied, usually because of invalid access credentials (LE_MRC_REG_DENIED)
Signal : very strong signal strength
PS : Packed switched not registered (LE_MRC_REG_NONE)

any suggestions or solutions please.

have you set the APN yet?

What is the following AT command response?
AT!SELRAT?
AT+CGDCONT?
AT!BAND?
AT+CPIN?
AT!GSTATUS?

Thanks JY

Seems this is a test SIM.
Have you tried with real network ?

The real sim works fine.

To connect to Agilent Wireless communication test set, I’m forced to use Agilent USIM.

i have never used Aglient machine with WP77 before , have you confirmed the APN is correct?
