I was using Titanium Backup to uninstall the bloatware on my phone and I came across an entry called SIM Toolkit. Titanium Backup labels it as a system app and I was wondering what it does and if it would be safe to delete considering the Prevail is a CDMA phone and does not use a SIM card? I've looked through all of the threads on here and I can't seem to find an answer to this.
