Services-Based Operations (SBO) Licence


The Service-Based Operations (SBO) Licence allows an operator to provide services-based telecommunications services in Singapore. Learn more about the requirements and regulations set forth by IMDA to ensure compliance with regulatory standards and promote a competitive market environment.

Who is this for?

Operators who intend to:

  1. Lease telecommunication network elements (such as transmission capacity and switching services) from any IMDA-licensed Facilities-Based Operator (FBO) to provide their own telecommunication services;
  2. Resell telecommunication services of FBOs to third parties; or
  3. Deploy telecommunication network, systems and facilities within their own property boundaries, but wish to offer telecommunication services to third parties residing within their property boundaries. 

Depending on the scope of the operation and nature of the service, a telecommunication service-based operator can be licensed under one of two categories:

SBO (Individual) Licence 

  • In general, operators who lease international transmission capacity to provide their services would be licensed individually.  
  • These would be companies incorporated or foreign companies registered under the Companies Act 1967.

SBO (Class) Licence 

  • A range of telecommunication service-based operations and services fall under this category.  
  • These may be companies incorporated or foreign companies registered under the Companies Act 1967 including Limited Liability Partnerships or Limited Partnerships.

For more information about the two categories of SBO Licences, please refer to the SBO Guidelines below.
