If your product or service requires a phone, I just don't do business with you. I know I sound archaic recommending this, but we (as a society) need to push back on your phone being the key to your life.
My phone is no more special than my laptop, however this requires an incredible amount of inconvenience for most people along with the constant social pressure to carry a cellphone. As you can imagine, I do not have many friends these days.
