    It just cant verify the old pin we are using it in wp8.1
    So we have to either disable it or change it
    To make it work again

    If your phone locks up when entering the sim pin , press cancel and go to settings>system>phone and disable the pin
    Just enter the pin there if prompt
    While disabling it

    Or just hard reset ur device

    Device asked for pin, then crashed/powered off. In settings/phone I have "No SIM", so cannot disable pin. Soft reset doesn't help. "No SIM" icon is showing in notification bar.

    Here are 3 Solutions

    1.
    Disable SIM PIN in Settings -> System -> Phone
    Or Change SIM in this menu

    Settings App crashes for many ppl after pressing phone
    - Power off your device
    - Remove SIM
    - Power On
    - Open Settings -> System -> Phone
    - Power Off
    - Insert SIM
    - Power On
    - Cancel SIM PIN
    - Go to Settings -> System -> Phone
    - Change or Disable SIM PIN
    Your fine to go

    If you only change your PIN you never can enter SIM PIN on Startup, you have always change it in settings! Entering at phone hub or startup will hang up your device!

    2.
    Disable SIM PIN in a second device and it will work in ur win 10 device
    Works for the most

    3.
    Hard Reset, hard but works for the most and when theres no second device only solution if 1 Fails


    Hope this helps you to resolve this issue

    I had the same problem of you (System -> Phone crashing and reverting back to the home screen), but after a couple of soft reset it went okay. Keep on trying, guys.

    (Still, it's incredible how buggy this fundamental feature is)

    Not sure if its the same issue on my 920... SIM card not recognized or detected. My Phone app opens and I see it asking for a voicemail password. Then the app quickly crashes before I can do anything. If I try to go to Settings->System->Phone, sometimes that crashes and closes and other times it shows empty information and I can't change anything. The "My phone number" is empty. It says "We're having trouble saving your voicemail number right now. Try again later".

    If I go to Settings->Network & wireless->Cellular+SIM, the "Active network" says "cellular turned off". I have no idea how or where to turn it on. It looks like there is a "SIM settings" button at the bottom, but pressing it does nothing.

    I know we signed up for a Tech Preview here. But I assumed since it is software for a phone, the phone feature would actually be present and working. Not sure what to do at this point except use a different phone until this gets fixed.

    This is why they asked us to mainly use it on a secondary phone :) At this point we will have to wait for a bug fixing update

    That's kinda the problem - "fundamental" to one person is irrelevant to another.
    I've not seen a SIM PIN used for 10+ years.

    Amazing, I have a Lumia 535 and was unable to use my SIM (Dutch Network), as it froze the entire phone to which I had to remove the battery or hold the power button.
    Disabling the Sim Pin instantly fixed the problem. You, are a saviour!
