IMDA freezes M1-Simba merger review over alleged spectrum breach

The investigation targets potential breaches of the Telecommunications Act 1999.

The Infocomm Media Development Authority (IMDA) has suspended its assessment of the proposed consolidation between telecommunications operators M1 and Simba until further notice.

The move follows an investigation into Simba’s alleged unauthorised use of spectrum.

In a statement on 18 May, IMDA said it had been reviewing the proposed deal under the Telecom and Media Competition Code, including whether the transaction would substantially lessen competition or raise public interest concerns.

The review also covered cybersecurity requirements tied to the operation of critical telecommunications infrastructure, noting that M1 operates large mobile and broadband networks in Singapore.

“Whilst the review was in progress, IMDA learned that Simba could have been using radio frequency bands that had not been assigned to it to provide mobile services,” the regulator added.

Such use would constitute unauthorised use of the frequency spectrum and may breach the Telecommunications Act 1999 and the conditions of Simba’s Facilities-Based Operations Licence.

IMDA said it is investigating the matter and will take enforcement action if the breach is established.

In a separate announcement, Keppel Ltd. and Simba extended the long-stop date for the proposed divestment of M1 to 21 May 2026.

The original deadline was set at six months from the date of the application’s submission, with provisions for extension by mutual agreement.
