CNA Explains: What could happen to Simba customers if IMDA takes action against alleged unauthorised spectrum use?

If the Infocomm Media Development Authority (IMDA) finds that Simba, a major mobile operator in Singapore, has engaged in unauthorised spectrum use and other regulatory breaches, the telco could face consequences such as fines, suspension, or cancellation of its licence. While Simba customers have been assured that their services, plans, and wallet balances would remain unaffected during the investigation, these outcomes are possible if the allegations prove true.

A financial penalty would likely have the least disruptive impact on customers, with no immediate effect on service quality. However, restrictions on spectrum use could result in reduced network capacity and service quality, potentially leading to slower data speeds and congestion during peak periods. A more severe outcome would be the cancellation of Simba's operating licence, which would be unprecedented for a major telco in Singapore.

In such a case, customers may need to switch to another provider, and the government would likely provide a grace period for customers to make the transition.
