@Rocket @deprecated_ii Unironically if someone was in electrical engineering and whatnot and had the resources to just make a cheap dumb phone.
You could probably make an absolute killing by getting a school board to ban all cellphones except for your mandated dumb phone that can only do talk and text, if parents wanted to be able to communicate with their kids while at school.
Since I believe schools are starting to look for a smartphone ban on top of removing laptops from the curriculum.
