Simba under scrutiny in Singapore for using unassigned frequencies

Published on May 21, 2026 | Translated from Spanish

The Infocomm Media Development Authority (IMDA) is investigating whether Simba, a telecommunications operator in Singapore, violated regulations by using unassigned radio frequency bands for mobile services. The case arises during its proposed acquisition of M1, adding regulatory pressure to the process.

The radio spectrum and its technical limits 📡

Frequency bands are assigned by license to prevent interference between operators. Using unauthorized bands can degrade service quality and affect other spectrum users. The IMDA is verifying whether Simba used frequencies reserved for testing or internal use in commercial operations. If confirmed, sanctions would range from fines to license revocation, complicating its plan to purchase M1.

The lion that roared on the wrong frequency 🦁

Simba, which presents itself as the defiant lion of the market, now seems to have roared on the wrong channel. It is not the first time a small operator has tried to bend the rules to compete with giants. But if the IMDA finds faults, the lion could end up tamer than a kitten, and its acquisition of M1 would become a mere meow.
