Is Unihertz smartphone compatible with major US carriers?
We have recently made an announcement on the connection issue with AT&T.
According to the feedback we receive from users recently, you can still use the smartphones on Verizon and T-Mobile.
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.
