I've purchased an unlocked AT&T phone LGE LG-D800
After calling T-Mobile and configuring APN, I can now get 4G. However, I still can't tether. The T-mobile rep said I am out of luck and can't tether with stock tethering application, because it's looking for AT&T servers. He did not way whether a 3rd party app would tether for me, and none of the apps I downloaded worked.
I am thinking, there has to be a way to get it to work: after all, the phone has data, it has wifi, all I have to do is bridge them, right?
I am a Java developer. Never programmed Android but would like to start; so if it comes to that, a programming solution would work.
Surprised with the lack of data on the web! One would think there are lots of people like me!
P.S. I don't care whether the solution involves wifi, USB or Bluetooth.
The error message is as follows:
authentication was unsuccessful There is a temporary network problem that prevents the enablement of the USB tethering function. Please try again later.
