SIM PIN2 to unlock mobile broadband device

My new Laptop is a Lenovo T470s (S/N PC0PXLX1) with a "Sierra Wireless EM7455 Qualcomm Snapdragon X7 LTE-A" WWAN card. 

After working well for 6 weeks, I am now unable to get an internet connection using that adapter.

Windows 10 network diagnostics tells me I need to "Enter a SIM PIN2 to unlock the mobile broadband device". I can find no way to enter anything.

Tech support at both AT&T and Lenovo have never heard of SIM PIN2 and each blames the other for the problem. I have talked to each several times and have been referred to "advanced tech support." 

My internet provider is AT&T.

This community has referred to a "provider specific software" that solved one participant's similar problem.

My provider, AT&T, has given me two PUK numbers. I suspect their PUK2 may be the SIM PIN2, but I still have no way to utilize that information.

HELP!

    Hi Jack,

    If you are programmer or analyzer of network, maybe you are install the software named Wireshark to capture the network package, but I found that Npcap will instead winpcap at the new version of Wireshark, and the Npcap will be the reason of you received the message "Enter a SIM PIN2 to unlock the mobile broadband device".

    You can try to uninstall the Wireshark and Npcap, and removed a network adapter name like "Npcap Loopback". My laptop is worked successfully when I finished uninstall software and remove the network adapter.

    I hope this can help you.

    I have the same issue on the dell latitude 7212. It asks for me to enter the pin2 number that I have from the network operator just that I have no idea where to enter the number.

    I thought I explained my steps pretty well in my post.  What part wasn't clear?  What make and model of laptop do you have?
