Here is the answer to the billing cycle following a chat with Fizz:
If you sign up on day #D of a given month, your next billing cycles start of the day #D of every subsequent month. I didn't ask but February 29th would be an exception.
It’s monthly billing. Not 30 days recurring billing.

Yes Ed it's the way it's work.
Hi Ed,
As others have stated above, this is the correct way that any prepaid service works, it is renewed the following month on the same day that you started your plan.
Cheers,
