Simba faces possible fines, licence cancellation over allegations of intentional spectrum misuse
Singaporean telecommunications operator Simba faces potential fines, license suspension, or cancellation due to alleged unauthorized spectrum usage and regulatory violations, according to disclosures made by its Australian parent company, Tuas. The Infocomm Media Development Authority (IMDA) has issued a notice to show cause detailing six specific allegations, including the intentional deployment of dynamic spectrum sharing technology at approximately 133 sites to use the 2100 MHz band for 4G services, despite authorization limited to 5G. Additionally, IMDA alleges that Simba utilized the 2340-2360 MHz band at around 92 sites without proper authorization and deployed 5G indoor equipment prior to receiving necessary approvals. The regulator claims these actions were deliberate and approved by senior management, while also citing failures to fully comply with document production orders and broader deficiencies in corporate governance. These allegations led IMDA to suspend its review of Simba’s proposed $1.43 billion acquisition of rival operator M1 in May, a deal that was subsequently terminated.
Singaporean telecommunications operator Simba faces potential financial penalties and the suspension or cancellation of its operating license following new allegations that it intentionally misused radio spectrum. These claims were detailed in a regulatory notice disclosed by Simba’s Australian parent company, Tuas, on Monday. The Infocomm Media Development Authority (IMDA) issued a show cause notice outlining six specific allegations against the telco. Among these are charges that unauthorized spectrum usage was deliberate and sanctioned by senior management, as well as accusations that the company deliberately failed to comply with orders to produce documents. The regulator alleges that Simba deployed dynamic spectrum sharing technology at approximately 133 sites during intermittent periods in 2022 and 2023. This technology permits different generations of mobile networks, such as 4G and 5G, to share the same frequency band. By doing so, Simba allegedly utilized the 2100 megahertz band for both 4G and 5G services, despite holding authorization strictly for 5G use in that range. Additionally, IMDA asserts that Simba operated within the 2340 megahertz to 2360 megahertz band at roughly 92 sites for intermittent periods spanning from 2023 to 2026 without proper authorization. The authority states that both instances of unauthorized usage were intentional acts approved by the company’s leadership. Further allegations include the premature deployment of 5G indoor radio access network equipment at two locations in 2023. Approval for this equipment was not granted until November 14 of that year. IMDA also cited a deliberate and intentional failure by Simba to fully comply with a document production order. The regulator expressed concern regarding deficiencies in Simba’s governance and compliance culture, suggesting these issues warrant additional regulatory oversight. Potential sanctions include financial penalties amounting to either 10 percent of the annual turnover of the relevant business segment or one million Singapore dollars, whichever figure is higher. Other measures under consideration involve the suspension or cancellation of Simba’s spectrum rights or telecommunications license. The regulator may also shorten the duration of the existing license or impose extra obligations to rectify governance shortcomings. Simba has until November 16 to submit its response to the notice. The current escalation follows an initial disclosure by IMDA in May regarding an investigation into possible unauthorized spectrum use. At that time, the regulator suspended its review of Simba’s proposed 1.43 billion Singapore dollar acquisition of rival operator M1. The deal was subsequently terminated. In September, Simba acknowledged using spectrum beyond permitted limits. Management attributed the unauthorized usage of the 2300 megahertz spectrum to a combination of hardware and software issues, though no further technical details were provided. Tuas stated in its filing to the Australian Securities Exchange that IMDA has not yet concluded whether regulatory action is warranted or what form such action will take. The company indicated that Simba intends to respond to the show cause notice by the deadline. Tuas declined to offer further comment while the matter remains under regulatory consideration. Market reaction to the disclosure was immediate and severe. Tuas shares dropped more than 33 percent after trading began on October 26. The stock traded at 1.21 Australian dollars as of 9:50 am, a decline from its previous closing price of 1.81 Australian dollars. Spectrum, comprising invisible airwaves that carry communication signals, is allocated by IMDA to mobile operators for dedicated use. Operators are restricted to utilizing only the specific frequency bands assigned to them. The recent allegations suggest a breach of these fundamental operational constraints, leading to the current legal and regulatory standoff. The outcome of the investigation will determine whether Simba retains its license to operate in the market or faces significant structural changes mandated by the government.
Singapore’s Infocomm Media Development Authority (IMDA) has escalated its investigation into Simba Telecom, alleging that the company intentionally misused radio spectrum at over 100 sites with approval from senior management. According to a filing by Simba’s parent company, Tuas, the regulator issued a Show Cause Notice detailing unauthorized use of specific frequency bands for 4G services and unapproved 5G deployments between 2022 and 2026. These violations reportedly contributed to the collapse of Simba’s proposed $1.4 billion acquisition of M1 earlier in the year. In addition to potential fines reaching up to $1 million or 10% of annual revenue, Simba faces the risk of having its operating license suspended or cancelled. Tuas shares dropped significantly following the disclosure, while the company stated it would respond to the regulatory notice by the November 16 deadline.
