I've had the lowest cellphone plan available with Cingular for as long as I can remember. I had to change my number and wasn't able to get the current plan I was on (200 min for $19.99) so I had to go to their new lowest plan (450 for $39.99). If you don't talk a lot (like me) you'll have tons of rollover minutes. At least you get to keep the minutes you don't use, but most of mine go to waste. I don't have a text plan because I don't text much, but each one I send and receive costs me $0.10. If you text a lot, I recommend getting a higher plan that includes text messaging, but if you just need a simple plan and like having a cellphone for the convenience, the 450 minute plan will work for you.
