With prepaid unless you subscribe to unlimited service there are no free night or weekend minutes, no free mobile to mobile minutes. With many prepaid unlimited plans there are no free roaming and no service off network.
For example Consumer Cellular works like postpaid service and requires no contract. They offer a base rate of from $10.00/Mo with a charge of $0.25 per minute up to $57.00 for 2,400 minutes/month for the first handset and around $10.00 for each additional handset sharing the same bucket of minutes. No free mobile to mobile minutes so you pay two minutes per minute for calls between handsets on the same account. No roll over of unused minutes. On the plus side CC uses AT&T network and there are no roaming charges.
One has to read the fine print in order to see if the prepaid MVNO's plans will be economical for your use of your cell phone.
