An interesting article in the Times of India, documents the varied use of missed calls among mobile phone users in India, based on LIRNEasia’s T@BOP3 findings for 2008.  Although the title of the article is slightly misleading (missed call use was, in fact, prevalent in all the countries studied;  see here for more information), it nevertheless brings home the point that missed calls are being regularly used to communicate messages of various kinds in different contexts.
