For those not familiar with Republic Wireless, they are a North Carolina based Mobile Virtual Network Operator (MVNO). They differ from the other MVNO's out there by offering hybrid calling. Hybrid calling allows you to use existing Wi-Fi networks for calling, text and data. If you are not within range of a Wi-Fi network, in all but the cheapest plan your phone automatically switches over to Sprint's network.

In the case of the Motorola Moto G phone used in this review we are limited to 3G service, but if you opt for the more expensive Moto X you would get 4G LTE coverage where available. While enabling Wi-Fi calling is not new, the purpose is. For instance, T-Mobile offers Wi-Fi calling to supplement poor signal quality, especially indoors. Republic Wireless is offering hybrid calling so that they can offer very competitive rates; starting at just $5/month and topping out at $40/month for unlimited talk, text, and 4G service. But the truth is the real cost savings is on data use. By utilizing these Wi-Fi networks for data whenever possible saves big money for everyone. Below is a chart of available service levels and their costs (more information here).
