My phone currently requires a SIM-PIN in addition to the pin to unlock the phone, which feels a bit redundant. How can I remove the SIM-level PIN?

I have looked through all the areas of settings and can't find it anywhere.


You can disable SIM security at the bottom of "phone settings", accessible from the menu of the phone application/dialer. You will need to enter the SIM PIN in order to disable it.

"lock + wallpaper" only provides access to the phone PIN.

  • This answer is outdated, the procedure is different since Windows Phone 8.1 GDR2 (8.10.15148.160), see my answer below. – Manuel Durando Jul 10 '15 at 22:25

On my Lumia 830, running Windows Phone 8.1 GDR2 (8.10.15148.160) the answer above is not valid anymore.

Instead, I succeeded in removing the SIM PIN security at phone boot by following this procedure; I just swiped on the button SIM security to turn it off.

On Start Start icon, tap Phone Phone tile > More icon > Settings.

Turn off SIM security Toggle switch

Please note, the phone will ask you the SIM PIN one last time.

  • I'm not sure what model I have (that's hard to find out too) but your answer was very useful to me. I would never have looked there! Under Settings I have "mobile+SIM" and below that "SIM settings" and that's NOT where you can activate/deactivate SIM lock - makes no sense – CodingYourLife Jan 9 '17 at 18:56
