Notable KaiOS Phones

Of the 100+ KaiOS phones sold around the world, a few are superlative and worth noting. While Reliance’s JioPhone is undoubtedly the global best seller with well over 100M units sold, several other models made history.

The Prequel: The GreatCall Jitterbug Flip

The GreatCall Jitterbug Flip (aka Alcatel Go Flip) was a very simple flip phone designed for senior citizens. It’s big buttons, large text, and simple menu made navigation a breeze. When it was released it 2016, it ran Firefox OS 2.2, the predecessor to KaiOS. The Jitterbug Flip was later updated to KaiOS 2.5, in part, to deliver VoLTE support. Despite not being marketed with KaiOS, in a way, the Jitterbug Flip was the “first” KaiOS phone.

The First: Alcatel Go Flip 2

The first official KaiOS phone was the Alcatel Go Flip 2. Released in 2019, it supported all major North American carriers (e.g., Sprint, T-Mobile, AT&T), this launch proved KaiOS is stable, secure, and scalable. Otherwise, from the outside the Alcatel Go Flip 2 is nearly identical to all other Go Flip models. Other varients including the Cingular Flip 2 and Alcatel OneTouch (4044) ran KaiOS 1.0 based on Gecko 37 and lacked the KaiStore.

The First with KaiOS 3.0: Alcatel Go Flip 4 and TCL Flip Pro

Released in 2021 at the same time, the TCL Flip Pro (Verizon) and Alcatel Go Flip 4 (T-Mobile) were the first with KaiOS 3.0. Each sported a Qualcomm 215 and were noticeably snappier than KaiOS 2.5 devices. KaiOS 3.0 was baded on Gecko 84 and isn’t backwards compatible with KaiOS 2.5. As a result, each device launched without support for major applications like Facebook or WhatsApp (which are still not supported in 2024).

KaiOS 3.0 Outside USA: Orbic Journey Pro 4G

Three years after it’s initial release, KaiOS 3.1 finally made an appearance outside of the United States with the launch of the Orbic Journey Pro 4G in Japan. What’s more, it’s KaiOS’ first phone sold in Japan!

KaiOS Home Phone: Kammunica La Mano

Kammunica’s La Mano is the first “fixed wireless phone” using KaiOS. It’s essentially a landline home phone that makes calls wirelessly over Wi-Fi (VoWiFi) and 4G LTE (VoLTE) and comes with a charging dock. Otherwise it runs KaiOS 2.5 indistinguishable from other phones.

Developing for 100+ Devices
