Which company’s prepaid cell phone minutes last the longest before the expire. And rollover doesn’t count if you have to buy new minutes in order to rollover.

For example, AT&T’s minutes expire in 90 days, unless you buy $100 worth of minutes, which expire in 1 year.
Virgin Mobile minutes do not expire, as long as you buy $20.00 every 90 days the minutes just keep stacking up forever.

T-Mobile:
“Promotion through 12/31/2004: Airtime refills of $25 and greater are good for one year”
I’ve got a T-Mobile prepaid phone. When I got it this summer what minutes I paid for were good for a year. The salesman commented they also like to run this promo around Christmas. Thus for $25 I can extend my minutes until New Years Eve at the end of next year if I re-up 31 Dec. 2004. Thus check out the deals T-Mobile has today, and your minutes will be good for a year.
