Volk One is a smartphone that doesn't need carriers.
The Volk Fi network is secure, censorship resistant, and available to everyone that is scheduled to be shipped in December (2019).
"Volk One comes with a charging pad that also contains WiFi and an RF chip used for Volk Fi connections. So, you are not going to get wireless charging from half a mile, but you will be able to connect to transfer data from long distances."
If there is no Volk-Fi router or Volk One phones within range, you will need either a WiFi connection or a cellular connection. (Via SIM card from your carrier.)
