While your treatise on remote communication and numerology in the post-modern global technology marketplace raises several important issues about accesibility as a function of mobility, it is a fundamentally flawed argument since you do not take into account number systems with bases other then 10. For example, if the operator "Call Me", defined as sigma, or 530-356-0092, is converted to a binary number system in a dimensionality other then R3, you can no longer pinpoint the eigenvalue, "John", as being within the confines of given space time. Furthermore, by changing the parameters to a number system base 7.45 ln 7, and operating within 6 or more dimensions, then John becomes a prehistoric ape circus performer/explosives edibility tester and can no longer engage in mobile communication.
