MaxineN:
If customers wanted endless why not just go full steam ahead and just make 1 plan endless with no data cap or soft cap.
Then it would be truly endless and not this endless till you hit an arbitrary limit.
Shake up the market like you used to.
As an ex customer I would highly consider coming back if there was 1 endless plan with truly unlimited data at a fixed price with the option to share/tack on other devices into 1 bill and add an incentive to do this. There's more value to customers then these new plans. Go all the way. Seriously.
I suspect 2degrees would like to make some money on their products and services. What price would you pay for a fully unlimited plan with no data caps or throttling?
Obviously these exist in fixed wireless broadband but that's a very different proposition.
