Monthly charge is $19.95 - the recurring billing takes place on the 28th of the prior month. Quarterly charge is $59.85 and takes place of the 28th every three months. They are both $19.95 per month but if you can pay for three months in advance, we reward you with 1000 long distance minutes per month instead of 300 long distance minutes per month
