What happened to tethering in Android?

Episode 1039 (1:11:58)

Frank from Vancouver, WA

Frank has a Google Nexus 7 and has been using tethering. He updated the OS to KitKat and the tethering option has disappeared. When he takes the SIM card out, it reappears, but when he puts it back, and it disappears again. Leo says that it's likely AT&T doing that. They want to charge him for hotspotting and tethering. If he doesn't pay for it, they're not going to let him do it. It's also happened to T-Mobile users. Some solutions will require him to root his tablet, which is certainly possible.

The Chatroom says that ES File Explorer Manager has tethering and hotspotting built into it, so he can use that to work around it.
