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.

For Verizon users:

Our phone can work fine in Verizon network. However, as it is not certified by Verizon, you cannot activate your new SIM card with it. Please activate the new SIM card with another Verizon certified device and then use it in your Unihertz phone.

For T-Mobile users:

You can use the SIM card on Unihertz smartphones.
