Google Glass Explorer Edition XE 9 no longer requires Bluetooth data sharing tethering plan for via smartphones. Instead MyGlass now use a companion Android app for data sharing.
Google Glass is very much now in beta testing. The Explorer Edition of Glass has now been updated with new firmware. One of Google Glass Explorers, Nick Starr has shared on Explorer's G+ page (via Engadget) that Google Glass no longer requires a dedicated Bluetooth tethering plan for smartphone data sharing.

He stated, "XE 9 and Bluetooth data. Anyone else seeing this now? I turned off bluetooth tethering and confirmed that I still show Bluetooth data on Glass and am able to perform searches, turn by turn, SMS, etc. Seems as if data is coming through the MyGlass app now (there are bi-direction icons next to the MyGlass app in the notification bar)."
It means that tethering plan has been removed from Glass Explorer's edition. Google Glass companion Android app is now used for data sharing. A new app notification icon with 2 arrows is present there to show the sending and receiving of data. But this new feature is a big worry for carriers. But Google should not have to push back this feature in public version.
