rollover minuts vs pay

unfortunately roll over minutes have no monetary value, but they do prevent you from exceeding rate plan example would be

you on 450 min plan and have 3000 rollover and you use 2000 min you would have 1450 roll over min left and no overage charges so it would still be 39.99 = normal fees

without rollover  you would be billed 1550 min @.45 a min  = 697.50 = high overages 

rollover do not have any real monatary value but they do prevent you from having overages for minutes 🙂 hopefully this gives some clarity
