I just returned home from a trip to Bangkok and Bhutan. Civil unrest in Bangkok kept me from wandering as much as I would have liked. I had a lot of opportunity in Bhutan, however, to wander about and talk to people. As a bit of a background, Bhutan is a land-locked country bordered mostly by India to the south and China to the north. Much of the northern portion where we traveled is covered by mountains, so wireless is the primary infrastructure for communications. The average annual income is about $1,300, so they are not a wealthy nation. They've only been allowed access to TV and the Internet for about 10 years.
A consumer brand might argue that in a country where the annual income is only $1,300 and little infrastructure exists for the import of goods, there isn't much point in marketing -- let alone a digital marketing strategy that includes mobile. Countries like these are opening up, however, and their wealth is growing. Personal care products and Coca-Cola was on the shelves in most of the small shops we passed. In a country where cell phones certainly outnumber PCs and cellular connections (even if prepaid) must outnumber fixed, mobile has to be part of the mix.
Teenagers had cell phones. One of my guides had a Nokia N73 and the other had a Nokia Xpress Music. These aren't dumb or cheap text-only phones. They have high-resolution screens and are capable of music, videos and Internet. (My guide was checking and posting to Facebook DAILY.) Monks had cell phones. Women selling vegetables in open-air markets had cell phones.
