its a page that states tethering is not available for unlimited plans HOWEVER, if you don't want to give up an unlimited plan for tethering, they have these "riders" or packages you can add to your account for tethering called DATAPRO 5GB
but whats weird is when i try to go into the package, it redirects me to login when im already logged in. I can't find a trace of the feature on the site, nor can I add it to my plan. Which makes me confused. Why would their twitter help account give me a link to a removed feature. But I have hope they removed it to add it to their unlimited plan soon.
Who freakin knows at this point, AT&T get it together!
