Is Unihertz smartphone compatible with major US carriers?

For AT&T users:

AT&T released a whitelist of smartphone brands that will continue to work on their network after February 2022. Unfortunately, Unihertz products are not among them.

If you are using Unihertz smartphones (Except Jelly 2) on the AT&T network, it may not work normally. We are sorry for the inconvenience caused, though this has resulted from the carrier's policy change.
