The Only Thing Missing is 'Parental Control'
In VietNam and Cambodia parents give children far more latitude to 'do their thing', as is used to be before Nannies took over governing Britain or the USA. When I was young, I and my brothers roamed all over the area centred on the BBC transmitter at Brookmans Park and was measured in miles.
We often left the house early in the day only to return late in the afternoon when our stomachs were calling.
So it is today in Indochina. My daughter is free to go wherever she wishes in Ban Ma Thuot, Central Highlands, VietNam, a city of 1-million souls, with her Mother and I completely free of worry.
The secret is the cell handset. She can call when she wishes as can we.
The problem with today's handsets is the ease of dialling long distance/international calls. Providing a short, owner-entered, authorised calling numbers would add enormously to the value of this Nokia product.
Remember, in a country where the minimum wage is USD$50 per month, even a $25 Nokia dumb-phone represents a sizeable hit on a families budget.
