Bypassing Cellular
It’s common for smart phones today to fall back from cellular to Wi-Fi network connections. This mobile phone inverts that idea: Wi-Fi supplies primary connectivity for voice calls, but the phone defaults to the Sprint cellular network if no Wi-Fi network is available. The advantages are that users can buy the phone without a contract; service fees are a flat $19 per month. Previous smart phones that allowed voice-over-Wi-Fi calls required a contract with a carrier.
