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.
