I know that you can pay ahead with postpaid plans, and Boost Mobile is a prepaid MVNO, but there's a place in the app where it shows your current balance and it makes me think that you might be able to pay in advance.
It would be a lot more convenient if I could make payments, via CellNUVO, in $100 increments and not have to make a payment every month.
Hi, @Chelle, and thanks for your question, finally one that I can answer! (I think)
Unfortunately, after I tried to make a $60 payment via CN for two months' worth of service all at once, I found out that Boost only allows one month's advance payment at a time. Here's a link to their "rule" on this (second to bottom FAQ on the page):
So, I am making one advance payment each month, for the exact amount due, right after the prior one posts and the plan renews. Yes, it is more work to do it every month, but at least it's still free!
