Frank tried to teach his parents how to use a smartphone. Both Android and iPhone. It didn't go well. So he's looking to get a flip phone for them. But their carrier Verizon is pushing smartphones. Leo says they are pushing LTE phones because they want to decommission their old towers that flip phones rely on. Still, Verizon offers the Kazoona eTalk. As long as they are LTE compatible, they will be fine with a flip/feature phone. Look for a section on Verizon's website called BASIC PHONES.
Alcatel makes dumb phones as well. Look at the GoFlip V. Verizon sells it.
