The average call time per day in September for Jio was around 13 seconds, far lower than any other operator, according to Truecaller’s TrueInsights report for Q4-2016. Given the telecom operator’s interconnection issue peaked at that time, the statistic makes sense – call drops caused frustrated customers to not try calling again.

This is reinforced by the fact that Jio users also made the most calls per user out of any other operator, with average daily calls at nearly 5 in December, followed by Airtel at 4 and BSNL and DOCOMO at over 3.5. Additionally Jio’s focus on cheap data makes it a favourite among users for accessing internet with a 2nd SIM, rather than using it for calling.

Reliance Jio is also 2nd in terms of Truecaller users, behind Airtel, but ahead of Vodafone, Idea, Aircel, BSNL, Telenor and other operators. By region, the highest number of Truecaller users at over 5 million, came from Delhi and Maharashtra, followed by Andhra Pradesh, Mumbai, Karnataka, Gujarat, Tamil Nadu, Madhya Pradesh, Rajasthan and Uttar Pradesh East.

Interestingly, Jio seems to be equally good presence in all these circles, unlike Telenor which operates only in certain circles, or Vodafone, Airtel, Idea and others, whose numbers fluctuate quite a bit based on region. Interestingly, by call duration, the average length of calls by Jio customers was less than 30 seconds, the lowest of all operators, with Vodafone at the other end leading with an average call duration of 41 seconds.

Overall, TRAI’s data shows that subscriber base grew to over 1.12 billion by the end of November 2016, according to Truecaller’s TrueInsights report for Q4-2016. The report adds that Reliance Jio alone added over 16.2 million subscribers in November, taking the telecom operator’s total subscriber base to 51.87 million, within 3 months of launch.

As for the overall general calling patterns in the country, Kolkata users having the longest median call duration (42.17 seconds), while Jammu and Kashmir users have the shortest call duration (28.63 seconds).
