Reliance Jio emerged as the fastest mobile network operator in Mumbai with download speed of 248.93 Mbps, ahead of Bharti Airtel at 133.86 Mbps and Vodafone Idea at 89.04 Mbps, according to the latest drive test conducted by the Telecom Regulatory Authority of India (TRAI).
The TRAI network quality assessment, released on November 5, 2026, evaluated the performance of Reliance Jio, Bharti Airtel, Vodafone Idea and MTNL across Mumbai during September 23–25, 2026.
The tests covered 212.6 kilometres of city roads and seven hotspot locations, measuring mobile download and upload speeds, network coverage, dropped calls and call silence instances.
Reliance Jio Leads Mumbai Download and Upload Speeds
Reliance Jio delivered mobile download speed of 248.93 Mbps, approximately 86 percent faster than Airtel and nearly 180 percent faster than Vodafone Idea.
Airtel ranked second with 133.86 Mbps, while Vodafone Idea recorded 89.04 Mbps.
Reliance Jio also led upload performance with 33.87 Mbps, narrowly ahead of Airtel at 32.80 Mbps. Vodafone Idea registered 23.21 Mbps.
Reliance Jio had declared typical download throughput of 15 Mbps, compared with 23 Mbps for Airtel and 15 Mbps for Vodafone Idea.
Vodafone Idea Records Zero Call Drops in Mumbai
Vodafone Idea delivered the strongest call retention performance during the Mumbai drive test, recording zero dropped calls across 509 successfully established calls.
Airtel recorded one dropped call from 510 successful calls, representing a dropped call rate of approximately 0.20 percent.
Reliance Jio registered two dropped calls from 509 successful calls, resulting in a dropped call rate of approximately 0.39 percent.
MTNL recorded two dropped calls from just 32 successfully established calls, equivalent to 6.25 percent.
| Operator | Successful calls | Dropped calls | Drop rate |
| Vodafone Idea | 509 | 0 | 0.00% |
| Bharti Airtel | 510 | 1 | 0.20% |
| Reliance Jio | 509 | 2 | 0.39% |
| MTNL | 32 | 2 | 6.25% |
The results indicate that Vodafone Idea performed better than Reliance Jio and Airtel in call retention along the tested Mumbai routes, despite recording lower average data speeds.
Airtel, Jio and Vodafone Idea Show Strong Network Coverage
TRAI’s coverage measurements showed relatively few poor-signal samples across the three private mobile networks.
Airtel recorded 33 poor-signal samples from 58,003 samples collected, representing approximately 0.057 percent.
Reliance Jio recorded 87 poor-signal samples from 56,138 samples, equivalent to approximately 0.155 percent.
Vodafone Idea recorded just 11 poor-signal samples from 58,030 samples, representing approximately 0.019 percent, the lowest proportion among the three private operators.
| Operator | Poor-signal samples | Poor-signal rate |
| Vodafone Idea | 11 | 0.019% |
| Bharti Airtel | 33 | 0.057% |
| Reliance Jio | 87 | 0.155% |
| MTNL | 2,502 | 67.86% |
MTNL recorded 2,502 poor-signal samples from 3,687 captured samples, indicating significantly weaker measured signal performance.
TRAI reported 13,057 limited-service or no-coverage samples for MTNL, compared with zero for Airtel, Reliance Jio and Vodafone Idea.
Vodafone Idea Records Lowest Call Silence Instances
Vodafone Idea also performed strongly in voice continuity, recording one call silence instance lasting more than three seconds across 490 established calls.
Airtel recorded two silence instances across 479 established calls, while Reliance Jio registered three instances across 493 calls.
Call silence data was unavailable for MTNL.
The results indicate that Vodafone Idea experienced fewer voice interruption events than Airtel and Reliance Jio during the tested calls.
Mumbai Network Tests Cover Airport, Railway and Metro Locations
TRAI conducted its network assessment across major residential, commercial and transport locations in Mumbai.
The city drive covered Sion, Chembur, Deonar, Mankhurd Gaon, Tilak Nagar, Powai, Santacruz East, Khar West, Bandra West, Andheri East, Andheri West, Malad East, Kandivali, Borivali East, Mira Road East and Bhayandar East.
Seven hotspot locations were included: Andheri Railway Station, Chhatrapati Shivaji Maharaj International Airport Terminal 2, Deonar Metro Station, Infiniti IT Park, Kashigaon Metro Station, Lower Oshiwara Metro Station and Pandurangwadi Metro Station.
The tests evaluated mobile network performance across available 2G, 3G, 4G and 5G technologies using automatic network selection.
