One-way pagers are a thing if this is really a concern, but humans survived without phones for most of our existence. I do not carry a phone but my family gene

One-way pagers are a thing if this is really a concern, but humans survived without phones for most of our existence. I do not carry a phone but my family generally knows where I am if they need to call an office or a business to summon me in an emergency. I am offline, unreachable, and focused while driving, but I consider this a good thing.
