You can enable/disable/modify the SIM PIN on your device by following the steps outlined in this link: https://www.verizon.com/support/knowledge-base-239748/

If you forget the PIN and need to reset it, or don't have the default PIN in order to modify it, you can follow the steps in this link to obtain a new PUK as well: https://www.verizon.com/support/knowledge-base-47377/
