Data only as "add-on"

[Luddite]

Convert all data to "add-on" blocks (1, 3, 6, 12, 18 GB for example) that expire when used and NOT by time, with autorenewal once depleted. 

Perhaps priced in the current three tiers:

a) standalone

b) with calling, or texting

c) with calling and texting

Make PM truly unique in the markeplace!

i think the business model really won't allow  data  that doesn't expire until used.

they want people to buy monthly data that you might not use  and the high extra data costs are meant to encourage people to upgrade plans.

Brilliant.  There have been plenty of Lab ideas about plans, but this has to be among the best I've seen yet.

If my 12 GB rolled over indefinitely, I'd just be starting my second block.
