Tether with tmobile on htc one
I just got an HTC One unlocked by AT&T. So far it works fine on T-Mobile network except for tethering. I'm getting error "To enable tethering on this device, go to att.com/mywireless or dial 611". I have a post paid plan with T-Mobile and was able to tether on my Nexus 4. Is there any settings I need to change to make it work?
