A trade-free operating system, that's what Tromjaro means. But what does a trade-free operating system have to offer? Well, it means a lot, especially if you're tired of the imbalance between those who have versus those who want.

It is called the Jolla Phone and is advertised by Jolla as an "independent European Do It Together (DIT) Linux phone." Jolla says the Jolla Phone is a "real Linux phone" because it runs "actual Linux" on the inside, "not a pseudo-Linux." But that's at the core. From the user's point of view, you get version 5 of the privacy-focused Sailfish OS, advertised as the "only European mobile operating system."
