BTW as an early adopter who lived through some of those early mobile technology years I can tell you that the average person did not see the utility in mobile phones back in 1992 when I bought my first (analogue) mobile phone.  They were perceived as expensive to buy, expensive to use, battery life was poor, and most people frankly couldn't see the point.  In fact, most people back then saw mobile phones as the preserve of high earning bankers - and of drug dealers.
