Sim-Toolkit is missing from app drawer I am running Android 4.4.2 (KitKat) on an Nexus&nbsp;4.

A day before I changed from Dalvik to ART, and after the restart, I noticed that the Sim Toolkit is missing!

How do I get it back?
It may well just have changed name; check through all your apps. Happened to me a couple of times, so I assume it's just a carrier thing.
