Provider | CSSR (%) | Drop Rate (%) | Call Setup Time (s) | Silence Rate (%) | MOS (Score out of 5) |
---|---|---|---|---|---|
Airtel | 99.85 | 0.00 | 1.25 | 0.00 | 4.02 |
BSNL/MTNL | 91.75 | 0.90 | 1.56 | 6.95 | 2.91 |

Vodafone Idea | 100.00 | 0.15 | 0.77 | 0.56 | 4.53 |
🔍 Investor Takeaway:
📈 Vodafone Idea delivered best voice quality (MOS: 4.53), while Jio showcased lowest call setup time (0.72s).
⚠️ BSNL continued to lag behind significantly on almost every metric—highlighting operational inefficiencies that may impact user base and investor trust.
Although detailed throughput and latency figures per provider are not in this summary, the report reinforces rising user expectations from 5G-level performance in both urban and semi-urban corridors.
Rising 5G adoption
Rural network expansion
Mobile-first economy
Higher ARPU (Average Revenue Per User) with premium data plans
High spectrum debt
Intense price wars
BSNL’s underperformance dragging sectoral averages
Jio – Tech-efficient, lowest setup time
Airtel – Balanced leader with consistent performance
Vodafone Idea – Improving on voice, but stressed financially
BSNL – Public enterprise in urgent need of revamp
📊 Prefer private sector telecoms with strong customer service metrics, especially Airtel & Jio, based on TRAI's direct measurement data.
🔄 Expect 5G-related CAPEX to remain high but yield returns via network-led customer stickiness.
📉 Consider exposure to telco-support sectors (tower infra, cloud data services, fiber optics).
