We've gone many generations without cell phones at schools with trained professionals who are qualified to handle seizures. You don't need a cell phone to contact someone who can get medical assistance on a school campus.

I don't know how things work where your live, but I'm willing to bet my right hand that there is not a single person in my school that knows what to do in case of a seizure.

Epilepsy training is bog standard for teachers. Just because the kids don't know how to handle it doesn't mean that the teachers won't.
