I'm have a Samsung Galaxy S3 running Android 4.1.2 which I am trying to encrypt through Settings -> Security -> Encrypt Device. The process I am following is described in this article at Step 2.

Upon entering the Encrypt Device screen I am told to "Set an unlock password". How is this password set? My first guess was the Android Screen Lock, but within Settings -> Security I have no Screen option as I would have expected (shown in above article at Step 1). Could this be because I am using the device without a SIM card? If so, is there any other way of using this encryption method, potentially with an inactive SIM card that is not connected to any network?

The screen lock is set in Settings -> Screen Lock. The device can then be encrypted without SIM card.
