Judging by your choices here, I would strongly suggest you dig into what these phones can actually do.

The punkt phones, for example, have an extremely cut down set of features and are more like a dumb phone.

Volla phones are not certified for north america, so you will not get volte or half the LTE bands.

There are a lot of nuances to getting off the big brands and changing devices isnt just about leaving google and apple.
