Debated in Parliament on 14 Apr 2014.
Ms Lee Li Lian asked the Minister for Communications and Information in light of drop call rates published by IDA which state that subscribers should only experience 2.7 to 4.1 dropped calls for every 1,000 phone calls that they make (a) whether this accurately reflects what subscribers are experiencing on the ground; and (b) what measures are taken to ensure that the results are in line with actual experience.

IDA determines the drop call rates by auditing the mobile operators' respective network traffic logs. For example, in August 2013, the drop call rates on the operators' network were 0.27% (for M1 and StarHub) and 0.41% (for SingTel). Since the figures are derived from total set of network transactions, they are measuring the actual experience of the subscribers on the ground for that month.
