My AT&T version didn't have the toggle either I got this. It works great .I used it a lot the last couple months while I was saving mobile data for my road trips now that I dropped unlimited, but I'm good with my cap beyond that, so I leave it on now except when I'm at home and connected to my network. That way, if wifi happens to drop (hasn't that I've noticed, as I mentioned), I'm not burning mobile data in the foreground or background without realizing it.
