The amount of minutes you hve depends on the amount of the refill card. if u get a $10 one, u get 30 minutes. that charges approx. 33 cents per minte. it u get a $25 one, thats 130 minutes so about 20 cents and a $50 one gives 400 minutes so thats lyk 12 cents per minute. if u get $100 one den thats "gold rewards wenever minutes" and u get 1000 minutes (10 cents per minute) and the nxt u recharge ur account, u'll get more minutes...no matter wut the amount of the card is and the expiration date also gets extended to a yr.
texting is 10 cents to receive and 5 to send, but if u wanna work it out then it realli depends on the amount or the refill card. if its a $10 card then the ratio wud be 2 msgs (as in 2 sending and 2 receiving) to one minute. according to a $25 refill card, you can either snd to msgs or snd 1 and receive 2 for one minute and a $50 card has onli a slight difference (one minute to receiving and snding). If u refill it with $100, it'll change it cuz u'll be recieving extra minutes...one minute to snding one msg or receving two.
hope that helps
