With 60% of the population owning a mobile ohones, SMS has become one of the most preferred communications medium.
Today, a colleague of mine from Lithuania was showing me how to 
send a SMS message for free from the internet to a GSM mobile located anywhere in the world.  She said she normally uses SMS to communicate with her friends at home while in Prague.
This is very cool for a person coming from North America.  I have yet to discover the many possibilities of SMS and m-commerce.  The good news is there will be a 
HandyExpo taking place in Prague at the end of this month.  I am definitely looking forward to that.
