At times, many of us protect our phones by using a SIM lock PIN code. If we remember the SIM lock PIN code, then the steps below can help to remove it.
- Remove the SIM from the phone first.
- Then start the phone and enter the current PIN code.
- Go to Settings -> Security -> PIN Check. Change to disable. Re-enter the current PIN code.
- After this, the PIN code will be removed from the SIM.
If SIM lock PIN code is forgotten or lost, then ask your cell phone operator to give the PUK code, so that the SIM lock PIN code can be reset or removed.
