I don't know if they changed their rules, but I paid Verizon (back when they were GTE Mobilenet) 6 months in advance once so I could travel without having to worry about paying the bill. But that was before online payments were really a thing. The biggest thing you cannot prepay these days seem to be credit cards. None I have will let you make a payment with a zero posted balance.
To this day, I pay my bills when I receive them, not when the due date is.

My bill doesn't show up until a week before its due but if yours says it that early then pay it. Nothing wrong with that
