On November 8th, a new product is coming out. Bandwidth.com is launching VoIP for mobile phones.
“Great,” you say, “it happens all the time.” Well, this product release is special. Republic Wireless, they're calling it. It's not a softphone app, it's a new cell phone service for Android smartphones.
Republic Wireless will use "Hybrid Calling." The phone relies on Wi-Fi when available then automatically switches to cell networks when there's no Wi-Fi. Some premium VoIP apps can already do this.
