No-contract smartphone plans are all the rage these days. Instead of being locked into a high-monthly payment nightmare that never ends (unless you pay for early-termination fees), why not choose the comfort and convenience of a month-to-month deal? You can port your old number over or choose to get a new one altogether. And you don't have to worry about using some kind of ill-equipped smartphone from the mid-2000s either. These no-contract guys carry the newest gadgets you want and need.

Net10 Wireless is one of the more well-known no-contract wireless carriers. With a wide-array of plans such as unlimited talk, text and data starting at 40 bucks to pay-as-you-go set minutes plans, why not check 'em out?

Aio Wireless is another no-contact alternative. It's a brand-spankin' new wireless carrier that just happens to be a subsidiary of AT&T. That means that you get the assurance and reliability of AT&T's huge coast-to-coast network, as well as the speed you need to get things done over America's fastest 4G LTE Network. How does Aio (pronounced "A-O") work? Well, just bring almost any GSM-capable smartphone to an Aio wireless store and have the sales representatives hook you up with a brand new sim card. You can also order the sim card online and complete the installation process yourself.

Aio offers a variety of smartphones and feature phones. You can purchase an unsubsidized iPhone 5s or 5c or choose from a variety of Nokia Lumia Windows phone handsets. Android phones like the best-selling Samsung Galaxy S4 are also on tap. But remember that Aio Wireless only sells unsubsidized phones. And you'll have to pony up big bucks for the more premiere aforementioned smartphones. Cheaper phones in the 50 to 200 dollar range are available as well.

Big box retailers such as Walmart and Target also offer their own no-contract services.
