(ABC NEWS) -- Cell phones have become a part of everyday life. But that doesn't mean consumers are happy about the cost.

Many of us love our smart phones- minus the bills.

Consumer Reports says a new service provider, Republic, is offering an unlimited data plan for $19 a month.

That means you can talk, text and e-mail all you want, plus surf the internet.

The concept behind Republic's money-saving plan utilizes Wi-Fi to make phone calls.

"Republic Wireless makes it easy for you to make calls over Wi- Fi instead of cellular. Ultimately this saves them money, and you money," said David Toner with Consumer Reports.

However, Toner, who tested the plan, found that switching back and forth from Wi-Fi to cellular service can be tedious. He says the plan may not be for everyone.

If you're talking to someone, that person has to wait while you make a call to switch your service, then continue the conversation.

Republic currently offers just one phone- the Motorola Defy X-T, an Android smart phone that costs $259.

The price is high for a phone that is not top-of-the-line. It's only 3G, so when using cellular service, you won't get the fastest Internet connections.

But, the smart phone does have acceptable voice quality and a decent camera, Toner says.

"It's great if you're still carrying around an old flip phone and haven't upgraded because of high data costs. It's also good if you live in an area with spotty cellularcoverage, or if you're a college student and have access to a Wi-Fi network all over campus," said Toner.

He says if you can live with a fairly basic smart phone and service, Republic can be a real money-saver.

Consumer Reports says you can use Republic's tactics to save on your cell-phone bill no matter what carrier you use. Consumers can switch to Wi-Fi coverage from cellular service when at home or at the office to avoid going over the plan's allotment of data.
