Sprint PCS 5

Sprint provides me with cell-phone service for about $55 per year. How? I have a cheap cell phone that they sold me for $30, and I bought a 1000-minute pay-as-you-go card for $80 which includes free weekend time. Since I can't see why anybody would need to talk on a cell phone for more than 500 minutes a year, I would suggest Sprint. If I still felt the need for a monthly service (why?), I would have remained on Working Assets/CREDO, which after all gave me free ice cream. But who needs another monthly bill?
