As per the TRAI report, BSNL has lost 3,05,766 customers in the month of June 2025 alone. However, in the same month, Jio has added 19,12,780 connections and Airtel has added 7,63,482 connections. Undoubtedly, BSNL's customer loss is due to the poor quality of it's 4G service. In another reporting made in the New Indian Express on 24-07-2025, BSNL has performed poorly in the Independent Drive Test (IDT) conducted by the Telecom Regulatory Authority of India (TRAI) for the Uttar Pradesh (West) Licensed Service Area (LSA) in June. According to the report, BSNL recorded the highest call drop rate and the highest incidence of call muting among major telecom operators, including Reliance Jio (RJIL), Bharti Airtel, and Vodafone Idea. As per the findings, BSNL’s Call Setup Success Rate (CSSR) stood at 86.57%, indicating that nearly 13% of call attempts failed to connect. Its Call Setup Time (CST) — the time taken to establish a call — was measured at 3.03 seconds, significantly longer than its competitors. BSNL also recorded the highest Drop Call Rate (DCR) at 3.45% in auto-selection mode, suggesting major network issues such as poor connectivity or inadequate mobile tower coverage in the area. This comes despite government claims that BSNL has rolled out over 95,000 mobile towers across the country.
