Browsers not working."internal error"

[SdRasta]

I'm connected with a phone company called "simple mobile" . When i try to use internet with default "browser" or "dolphin" it says
" internal error Access is not allowed for this user agent in WWW.******.com" the "*" are whatever site I'm trying to go to. The only browser that works is "puffin"... all other apps that use internet work fine...
Anybody have any ideas how i can fix?

I Have a AT&T inspire.
