SMS seems to be especially popular in Asia (at least East Asia and Southeast Asia). Here people sent billions of SMS every year. So this seems to be quite a popular solution here. For example, a colleague just implemented a program which sends out SMS alerts (along with emails) to alert inventory issues. Here SMS is from 5c S$ (3.5c US$) down to free depending on the plan. Reference: 10 Billion SMS were sent in one week during Chinese New Year in 2006 in China. http://switch.sjsu.edu/mambo/switch22/mobile_pac_rim.html However it seems SMS is not that popular in USA. Maybe due to historical reasons. It is said that last time CDMA did not support SMS well.
