Model S 75 Phone as a key

Relying on the phone to open and start my S has bitten me in the ass twice recently in dead or no coverage area cell service. just too risky for me to do reliably.
BTW my wife really enjoyed getting dressed and coming to save me late at night with a key FOB!
I’m gonna pay for this one for the foreseeable future.
I think this should be a main takeaway from this thread for any folks that purchased an older used S and are wondering about using the phone rather than fob for unlock and start on a regular basis. It works, but in addition to wandering out of cell range, you can also inadvertently leave your phone in your car or the MCU could crash while you are away, both of which will trigger a call to an aggravated SO.
