See post below. Just put calandar in manual setting and roll it back one month and the hot spot will work once again. Verizon is working on a fix however.
You can fix it by changing the date back to May.
I guess Samsung hard coded into the device to not work past May( when the hotspot was supposed to stop being free).
So I guess you can always have mobile hotspot if you just change your date to a time when it was free.
I'm going to demand a free month of Hot spot usage after this fiasco. I will post here once I get it straightened out and everyone can call in with that number. I'm not going to let them screw us out of our extended free trial period.
