SIM PIN2 to unlock mobile broadband device

Anonymous

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!

    The networking test wizard did not show that NPCap was not compatible. Upon uninstall NPCap I was able to get lte working. 

    Thank you!

    Dear All,

    Having the same issue as indicated above.

    Initially was not even able to identify the network with the cellular network indicating "No Service" state and no Connect button available. When running "Diagnose" I got the same error as above.

    After updating drivers, status changed to "No Service" and now showing connect button. However, when trying to connect, it fails after about a minute and displays message - "Can't connect to this network. Contact your mobile network provider for assistance". Network diagnostic continues to display PIN2 error as before.

    Any suggestions?

    Hi Andre,

    I would like to follow up if you're still having this issue. If yes, I highly suggest that you contact your mobile network provider for further assistance. They have the necessary resources and tools to setup your cellular network.

    Feel free to post back should you have further concerns.
