The Mukesh Ambani led-firm may also start selling 4G-enabled handsets even before the launch as it hopes to build the device ecosystem by itself, Credit Suisse said in a report.
"With 70,000+ sites live (2,300MHz on all, 1,800MHz wherever Jio has the spectrum), we believe the launch is nearing for RJio. We expect a soft launch by mid-July 2015, which would be earlier than the current market expectation," the brokerage firm said.
Credit Suisse said it believes the impact on the rest of the industry from RJio's launch can be quite significant and should belie the recent optimism in the telcom stock prices.
The brokerage firm said its recent channel checks suggest that RJio's launch preparations are entering the final stages and the company is close to finalising wholesale distributors in most circles (the final step of finalising retailers can happen just a couple of weeks before launch).
"Our latest update is that RJio has shortlisted distributors in most circles. The high likelihood of RJio coming out with higher commission rates than market levels is getting some of the existing distributors we spoke to excited," it said.
Separately, the firm is building a device distribution network as it hopes to drive the 4G device ecosystem by itself involving low-cost 'Jio' branded handsets.
Operators in India do not sell handsets and there are separate distribution channels managed by handset OEMs and specialist logistics companies that do the same.
However, RJio is taking a different strategy and working on a dedicated handset distribution infrastructure, given that having sufficient 4G handsets supply is critical for their business.
"We understand the process of setting up device distribution is much more advanced than that of service distribution. In fact, it is likely that RJio starts selling devices before the 4G service launch so as to seed the market with devices prior to launch," it added.
Credit Suisse said from its discussions, it assumes RJio's internal target could be to sell two-thirds of all 4G smartphones sold in India through Jio's own distribution network.
"We believe if RJio comes to market with devices priced below $80-90 (roughly Rs. 6,000), it could be quite disruptive for the market," it said.
The report said with 18 data centres around the country, it suspects RJio probably already has the largest data centre footprint in the country.
Meanwhile, Reliance Industries Ltd (RIL) said in its annual report that RJio has been actively involved in developing the ecosystem for India's LTE phones, working with renowned OEMs, Original Design Manufacturers (ODMs) and chipset vendors on end-to-end device design and engineering.
"Reliance Jio Infocomm Ltd (RJIL) is ensuring the tight integration of these devices with Jio's network infrastructure, platforms and applications portfolio to ensure seamless experience to customers," the annual report said.
RJio is the only private player with pan-India broadband wireless access (BWA) spectrum. It also acquired spectrum in 800MHz and 1800MHz in auctions held in 2014 and 2015.
The report said RJIL's total equivalent spectrum footprint has increased from 597.6MHz to 751.1MHz (including uplink and downlink), strengthening its position as the largest holder of liberalised spectrum.
"RJIL is working aggressively in achieving the minimum roll-out obligations as specified in the notice inviting application for the spectrum auction in 2010, as per the Test Schedule Test Procedure (TSTP) issued by DoT in March, 2015," RIL said in the report.
RJIL has launched trial Wi-Fi hot spots across India and is in the process of entering agreements with various state and local authorities to provide Wi-Fi services, it added.
"RJIL is rolling out physical office infrastructure across 880 cities/towns across India," it said.
