ZTE Cymbal Z-320

First T-Mobile flip phone with Band 12 and VoLTE for better call quality and reception. Good battery life.

Doesn't do anything well except make calls.

There are very few good simple phones out there any more, and the Z-320 has a big advantage over older and cheaper alternatives like the Blu Tank II. It uses VoLTE on T-Mobile's dual-band LTE network, giving it much better coverage and clearer call...
