If you're talking about your FICO score reports, the sim is available on EQ and TU. They've never had it on EX --you might notice that EX also doesn't tell you what you're doing right on screen 2.
I think that there is a 3-in-1 service that has a simulator, and it's supposed to be more flexible that FICO's (wouldn't be hard), but since their scores are FAKO's, you're not going to get much benefit from running them through a sim.
