Missing "SIM Card Lock/Unlock" under security

[almacote]

I have a Credo/Sprint GS3 and, under Settings>Security, there is no option to turn the SIM card lock on or off. All the Videos and other instructions are showing something different than what I'm seeing. Any ideas? Thanks Screenshot_GS3_2013-04-18-07-50-35_zps433e76dc.png Photo by almacote | Photobucket

Sprint phones do not have removable SIM cards, so there's nothing to lock. I suspect the videos you've seen are for GSM phones, like AT&T, T-Mobile, or the international version.
