Gophone accounts do not allow for tethering. You will need an contract account with hot spot plan for that service. You own data having bought the 500 mb, but AT&T does have restrictions on the way the data can be used. One restiction is tethering.
I tried on my gsII with the gophone acount and can't tether either.
Yes, so its keeps telling me. Lol
I really don't need to, just wanted to see if I could. I can and do use my phone for any internet, I need, when away from home and wifi.
I am enjoying my phone. Thanks.
