That's true for their 200MB free plan (and it's quite understandable why they'd impose this restriction on that). No idea if they do the same for paid plans.
Ok so that is what it is then. You wouldn't be able to activate the 200MB free data on top of a paid plan for it to work properly. The SIM wouldn't work in the Verizon iPad until the 200 MB was used up on the TMobile iPad first.
