Republic hasn't disclosed furthermore details on phones the network will support. The company said more details will be made available on the launch date.

Bandwidth.com already provides the network, called Inetwork , for Google Voice, Skype, and Phonebooth , a VoIP (Voice over Internet Protocol) service for businesses.

Republic calls its Wi-Fi and cellular mixture "Hybrid Calling," a strategy it said reduces the costs for network services and makes the $19 flat monthly "membership" rate possible.

Republic estimates that smartphone users are within reach of Wi-Fi over 60% of the time, said the spokesman, Kevin LaHaise.

"We are in essence building the carrier you'd build if you had to do it all over again," LaHaise added. "Everyone loves their phones, nevertheless hates their network.

"Everyone else sets rules and limits and boundaries and makes it easy for you to cross them, to go over, and to rack up costs you didn't realize you were incurring," LaHaise said. "So what we're offering is a new network, with Hybrid Calling, a Wi-Fi-first mentality, a flat-rate membership with no contracts, no overages and no fees."

VoIP voice quality has improved significantly in recent years and is used widely by large corporations to support global customer contact centers and other functions, including employee-to-employee calling to reduce long distance charges.
