Mobile telephony has grown significantly in rural India, where 70% of the population lives. The rural market now represents the largest opportunity for growth, as urban growth rates have declined. Key factors fueling rural growth include the availability of inexpensive handsets, lower tariffs, and mobile operators sharing infrastructure to more easily expand to rural areas. However, challenges remain in profitably serving rural customers due to poor infrastructure, low average revenues per user, and the costs associated with distributing to new, first-time users in remote areas.
