Sure.

Consider buying a cheap feature phone. Keep it turned off as much as possible. Avoid SMS as much as possible. Use other methods for calling. (Perhaps Wire…?)

Aso, consider if all this trouble is really worth it. IMHO, it’s not. YMMV.

I'm curious, why should one avoid SMS? It's the ultimate tech that's not owned by any single entity.
