IIRC, when I went from PN 40/2 to the 80/20 trial it was something like overnight. I continued to pay the 40/2 price.
However, when the full products were announced I had to formally upgrade, to take place on my billing date, or revert on my billing date to the 40/10 that had replaced the 40/2.
Similarly when I later upgraded from 80/20 250GB allowance to the current Unlimited
that took place on my bill date.
