Since when? TMobile US? I've had Nexus and iPhone devices on multiple TMobile plans, never had any trouble tethering: just turn it on like normal for the OS. The only thing I've had happen was I think I remember some years back, I was on a grandfathered unlimited plan from before smartphones and tethering were ubiquitous, they started new plans with unlimited data+tethering and if I tethered too much it'd redirect to a captive page saying "please don't" and throttle me pretty heavily to convince me to switch, but the Simple Choice plan I have now is actually cheaper than that plan was.
