Factors Leading to Discovery of Unauthorised Use of Radio Frequency Bands for Provision of Mobile Services

Mr Ang Wei Neng asked the Minister for Digital Development and Information (a) when and how did the Infocomm Media Development Authority (IMDA) discover that Simba could have been using certain radio frequency bands to provide mobile services without authorisation; (b) how many telcos in the past 20 years have used radio frequency bands that were not authorised; and (c) what lessons can be learnt from the recent discovery of possible unauthorised usage.

This question has been addressed in the reply to a related Parliamentary Question by Associate Professor Terence Ho at the 7 July Parliament Sitting. The Member may refer to that reply. [Please refer to ​"New Safeguards following Probe into Simba Telecom's Unauthorised Use of Radio Frequency Bands", Official Report, 7 July 2026, Vol 96, Issue 32, Written Answers to Questions for Oral Answer not Answered by End of Question Time section.]
