I have an unlocked X on TMO, and a Nexus 7 (2012). When I tether my Nexus 7 to my Moto X, most things work - but Google Services don't. It's as if there is a host entry, DNS issue, etc. When I load a webpage, all is well, but if I try to open the play store, look at my sync status, etc, it is clear I am not able to talk to Google on the Nexus 7, when tethered to my Moto X on TMO.
I work w/ several people w/ TMO and other devices and it seems a bit inconsistent. My N7 played nice w/ an S4 on TMO, and that same S4 played nice when tethered to my Moto X. Any ideas?
I'd download some network dx apps right now, but well, I can't get stuff from the play store...
