How is this...
Pay as you go?
It seems like it's basically postpaid in advance.
Pay as you go is like my at&t phones that cost $0.10 per minute with no other charges for voice, text and data can be added monthly or at a high cost per text/Kb unit.
Exactly. PayGo is consumption/metered billing, not monthly billing. This is yet another prepaid-postpaid style brand under the already bloated Sprint umbrella (Sprint, Boost, Virgin Mobile, and a dozen MVNO's).
If you want true pay as you go on Sprint's towers, the closest you'll get is Ting.
Sprint is doing all they can to raise their brand. They offered this same service YEARS ago when it was Sprint PCS and their stores where Radio Shack, only not even a year later to cancel the service and move everyone to post paid services or cancel their services completely. This is why we have so many MVNOs and other companies trying to build out on their own in some markets.
