MDDI's Response to PQ on New Safeguards following Probe into Simba Telecom's Unauthorised Use of Radio Frequency Bands

Parliament Sitting on 7 July 2026

Question for Oral Answer

*47 Assoc Prof Terence Ho asked the Minister for Digital Development and Information (a) what safeguards exist to prevent telecommunications operators from straying into radio frequency bands that they are not authorised to use; and (b) whether new safeguards will be introduced, or existing measures strengthened, in the light of the recent probe into Simba Telecom.

Answer

On 18 May 2026, the Infocomm Media Development Authority (IMDA) informed the public that Simba could have been using radio frequency bands that had not been assigned to them to provide mobile services.

Mobile network operators (MNOs) must only use spectrum assigned to them. Any use of spectrum beyond the assigned bands without IMDA’s prior approval is a serious matter because it can cause interference to other services and allow operators to gain an unfair advantage over their competitors.

IMDA conducts regular technical checks and monitoring of MNOs’ compliance in spectrum use, with a primary focus on preventing interference in spectrum bands, and disruption of approved wireless and mobile services. Where interference has been detected, IMDA will work with the affected parties to minimise the impact and disruption to services, and take enforcement actions where appropriate.

IMDA’s investigations of Simba’s case are ongoing. We will need to let IMDA carry out its due process and conclude its investigations before further details can be shared.

Notwithstanding the investigations, IMDA will ensure that Simba continues to meet licence obligations and service level commitments to their subscribers.
