It’s essentially the poor man’s text message: a free way to nudge another person or company, but which comes in just one flavor. Indian cell phone subscribers, of which there are 900 million accounts, have a monthly average revenue per user of $3, which is rock bottom low for even a developing market.
Missed calls are being incorporated into mobile apps and services as a standard type of messaging like a text or an answered call itself. For example, an Indian cloud telephony service provider startup called KooKoo has been working with a Bangalore-based company to create an information market based around missed calls. If you want to know the latest weather, the latest Groupon-style deal, or the real-time bus schedule, you can send a missed call to the designated number and get an automated or manual voice call back with the answers you need.
