Prepaid cell phone plans used to be sketchy alternatives for those with less than stellar credit ratings, but not anymore. They can be ideal for anyone who's had enough of the restrictive two-year contracts, scary overage fees, or micromanagement of cell phone minutes. While prepaid cell phone plans used to be more expensive than traditional plans, costs have begun to fall. The plans have become just another way to break into the cell phone game. As the popularity of prepaid cell phones has skyrocketed, even the big brand-name carriers have jumped onto the bandwagon.

Prepaid plans are pretty self-explanatory: you open an account and pay for airtime up front. When you run out of minutes, you either pony up for more or, if you've had enough, simply let your plan expire. Want to switch carriers or cancel your service? No problem--you're not under contract, so you're free to jump ship anytime.

Though they can have advantages over traditional plans (see our cell phone buying guide for more information), prepaid plans aren't for everyone. If you must have the latest and greatest handset, if you're a heavy cell chatter, or if you want the lowest possible per-minute cost, you might be better off with a traditional monthly plan. But if you need the phone only for emergencies, if you use your mobile infrequently, or if you're simply a commitmentphobe who'd rather not sign a two-year contract, you're an ideal candidate for a prepaid plan. Not only can it save you money in the long run, but it can also be a great way for cell phone newbies to get their feet wet. For example, a senior citizen who has never used a cell phone may appreciate the simplicity, while a teenager buying a first mobile can learn the responsibility that comes with it.
