Teletalk has lowest call success rate, highest call drop rate: BTRC
State-run telecom operator Teletalk has failed to ensure the standard call success rate and call drop rate in Dhaka division, excluding two city corporations in the capital.
According to the result of a nationwide drive-test of the Bangladesh Telecommunication Regulatory Commission (BTRC), the average call success rate of Teletalk was 96.8 per cent while call drop was 2.59 per cent.
The call success rate should be 97 per cent or more, call drop should be less than 2 per cent and call setup time should be within 7 seconds, according to the policy of the BTRC.
