The Telecom Regulatory Authority of India (Trai) has received the maximum number of complaints for call drops against leading telecom company Bharti Airtel, followed by Vodafone India, Idea Cellular and state- run BSNL up to June 30 this year, telecom minister Ravi Shankar Prasad told the Lok Sabha on Wednesday.
The telecom minister said Trai has received 31 complaints of call drops against Airtel between January 1 and June 30 this year. This was followed by 17 against Vodafone and 10 each for Idea Cellular and BSNL. Similarly, eight complaints were received against Reliance Communications (RCom) and two against MTS India and one each against Tata Telecommunications and Aircel during the reported period.
Meanwhile on Tuesday, Trai made public its ground survey on the network performance of telecom service providers in Delhi and Mumbai where Bharti Airtel emerged as the mobile network with the least number of call drops in Mumbai , while in Delhi, Tata (CDMA) topped the list.
The results are based on network tests conducted in Delhi from July 9 and 11 and in Mumbai on June 23 and 24 by Trai.
According to the Trai benchmark, the call drop rate should be less than 2 %. Prasad said the performance of service providers against the benchmark for call drops is monitored by Trai.
The minister said Trai has laid down quality of service parameters for mobile phone services.
Prasad also said that the department of telecommunications (DoT) has asked Trai to give its suggestions if phone subscribers can be compensated for dropped calls.
