Necuno

The Necuno was a phone-like mobile device exclusively manufactured in Finland. The device was designed with a focus on enhancing security and user privacy by omitting the cellular modem, which prevented its use on conventional mobile phone networks. Instead it offered VOIP via a peer-to-peer encrypted communication platform called Ciphra. Standard cellular connectivity was planned for later versions.
