I guess I'm going to need to make a call to Tmo and see what's up? When I reached my 5gb of usage, tether got completely shut off. It would turn on, but what ever was connected and the only Web page available was a Tmo page telling me to add tethering to my plan. Bummer because a few months ago I would tether and my account would show no data usage under the tethering section. I was tethering away care free with like 15-20gb of usage. I'm just confused why I can't get it back? I've went back to the previous versions of my rom that worked and other ROMs I confirmed it working. I must have some sort of flag from Tmo or something. Besides going back to those roms, I've tried maybe 4 or 5 other methods and zero have kept my tether data usage showing no usage. If you or anyone knows how to fix this I would be very appreciative! If I would be OK with tether data throttled.
