Jelly Star not on Unihertz official "Telecom Compatible" List

Does any one have any idea why the Jelly Star is not on the official Unihertz "Telecom Compatible" List on their website?

I am seriously considering a purchase but I would really like to be able to confirm exactly what carriers and bands it works on.

I did send a message to Unihertz via their website and am awaiting a response. So in case no one here has the answer, hopefully I will soon enough! If so, I will be sure to share it here.
