The current version seems almost identical in hardware to the Nokia 4G. Some of these provide access to Jio multimedia streaming services, including local TV. The company even offers a pair of video out accessories to connect the JioPhone to a bigger screen and enjoy the content. There are even rumors of native WhatsApp and Facebook apps it's even featured in some of the screenshots, but it's missing from our store. Long story short, the Nokia 4G gets none of that and is, instead, stuck with a vanilla or international, if you will, version of KaiOS. This is a significant downgrade in functionality, to say the least.
There is a native app store with the following apps, currently in it: Twitter and Weather. That's it. These complement the legendary Snake, already pre-loaded on the phone as well as three demo version by Gameloft, that mysteriously popped-up only once we installed a SIM card in the unit. Things might change for the better in the future, but the current third-party app variety kind of limits the usability of the phone as a smartphone replacement.
It doesn't really help either that KaiOS is a very single-threaded OS, so to say, with little to no background task functionality. For general communication purposes over the phone or via SMS, that's no big deal, and there is push notification support, that instant messengers could potentially leverage.

Other than that, however, what you see is what you get. No multitasking to speak of. KaiOS store. This, in turn, means that you will have to learn the menu structure pretty thoroughly, so you can jump from place to place to toggle things on and off during use.
