BSNL has the highest rating for voice quality on calls, Reliance Jio and Vodafone in second place and Airtel in third place. This is evident from user feedback generated through the My Call app and published on the Telecom Regulatory Authority of India (TRAI) website. TRAI regularly updates this user data, which was first published on its website in December 2017, and rates popular Telecommunications Service Providers (TSP) between 1 and 5 for the call quality experience they deliver across the country. Although Vodafone and Idea have been merged to form Vodafone Idea (Vi), the data still distinguish and rank Idea in fourth place separately.
After this Data updated On November 5th, BSNL posted a cumulative user feedback rating for voice quality on calls of 3.4 / 5 on the TRAI website, calculated for a total of 2,014 samples. Reliance Jio and Vodafone have a rating of 3.3. It’s important to note that Jio has a sample size of 10,292, but Vodafone has a much smaller sample size of 3,408. Airtel with 9,520 feedback samples received a rating of 3.0 and Idea with only 977 samples received a rating of 2.9.
The data differentiates between call quality indoors, outdoors and when traveling. While the call quality ratings for the four indoor and outdoor TSPs are largely comparable, BSNL scores high for call quality while traveling with a user rating of 4.4 over Airtels 3.3 and Jios 3.2. The data is also assigned for each status and can be displayed individually for each TSP for the last four months.
The overall call quality of users in all states and across all TSPs raises some concerns. The user feedback examples say that only 60 percent of the calls were satisfactory, while 26 percent had poor voice quality and about 14 percent of the calls were dropped.
