The SuperInternet option activated starting from July 1st will be valid only directly form the mobile phone.
No more tethering (use of the phone as modem), USB keys and the likes...
.
Maybe they would not notice and let you do for long time the usual business, but be advised!
Everything should (I stress should) stay the same for options activated (and always kept on) before July 1st.
Cheers,
