Necuno
From Wikipedia, the free encyclopedia
The Necuno was a phone-like mobile device exclusively manufactured in Finland.[4] The device was designed with a focus on enhancing security and user privacy by omitting the cellular modem,[2] which prevented its use on conventional mobile phone networks.[5] Instead it offered VOIP via a peer-to-peer encrypted communication platform called Ciphra.[6] Standard cellular connectivity was planned for later versions.[7]

The Necuno was mostly open-source,[1] apart from an isolated firmware blob without access to the main memory,[3] used in the Wi-Fi driver for regulatory reasons.[8] The device used Plasma Mobile by default, but it can run a variety of open-source mobile operating systems.[2] It also had an ethernet port.[7]
