two types of prepaid plans: Pay As You Go, and Pick Your Plan. With the Pay As
You Go plans, you have two options. You can choose a simple plan which is always
25¢ per minute. If you use your phone more than 7 minutes per day or you talk
frequently with other Cingular customers, you should choose the other option.
You pay $1 per day (only on days you use it) and then the rate is 10¢ per
minute, but all mobile to mobile calls between Cingular customers are free. $15 top up lasts 30 days, $25 to $75 lasts 90 days, and $100 lasts a year.
