Sorry I was not complete in my posting....Pay-As-You-Go minutes have shelf life of 90 days and if you add another card to your account with minutes already on the balance, they are extended out 90 days along with the new funds...So, yes minutes "roll-over" but only if you add more minutes to the balance, extending all to ninety days from when the current reboost card was added...clear as mud, huh?

The Boost Premium Plan has a standard 200 daytime minutes given with the 49.99 and if you still have any of those 200 left at the end of the month you will lose them and get a fresh 200 with another debit of 49.99 from your Cc or Debit card...any funds left over from your pay-as-you-go plan or that are in the Low Balance Credit will not be lost from month to month....those do "roll-over" until you either need them for daytime overage, or if you want to buy any of the many products sold at "BoostLive" , like tones, wallpapers, games, applications, subscriptions.....
