There are quite a few security portals built into the Android OS to keep your device and its contents safe. While the solid passcode or fingerprint lock can be a robust defense, you can set SIM card lock on Android for an added layer of security.If your Android device is tied to a carrier like AT&T, the ability to lock or unlock your SIM card remotely comes automatically. However, almost all the Android devices these days have some form of settings to help you secure the data on your SIM card and prevent it be used by someone else without your approval.
