ci sono bei suggerimenti ....
Se il dispositivo è roottato sembra basti modificare un parametro dentro ad un file
Wait, is it not easier way to do this:
(if you have root)
1. download SQlite editor app from G.Play (pay for it few bucks)
2. search for com.android.providers.settings and open it
3. open "settings.db" then "global" and under "tether_dun_required" change 1 to 0,
save and turn on tethering without any limits.... Just after reboot you need to set 1 to 0 again to make it work...
I saw it somewhere around and that worked for me!
(Didn't have to change or create new APN.
(This is possible solution for NON-T-mobile users of D801 model, because I'm one..)
