December added 12M data users to 344M with 700M 2G feature phones the next target.
Rishi Tejpal, new telecom lead at Economic Times, introduced some dramatic projections in his first article. Bharti, Jio, and Voda/Idea intend to introduce 4G smartphones at 500 rupees, less than $10 U.S. He estimates that would require subsidies of ~$30/phone. The result: over 200M Indians will switch to 4G with Internet connections. I believe $5B for customer acquisition is modest compared to the $10's of billions each of the companies is spending for robust networks. (Jio and the others will generally offer >15 megabit downloads by the end of this year. Their state of the art 5G networks are bringing cost per bit so low they can make money at prices the West think remain impossible.)
Depending on how you count 2G and 3G mobile connections, India either soon will have more Internet connections than the U.S. population of 326M or may have already done so. Soon, India will have twice as many people connected at broadband speeds as the U.S., mostly on wireless. A dynamic private sector led by Reliance Jio is complemented by the sensible public buildout to over 300,000 villages. Both are moving quickly.
