The Ministry of Communication and Information (MCI, or KemKominfo) is in the process of issuing a Certificate of Operation Eligibility (SKLO) to Indosat Ooredoo, as it looks to ready the launch of its 5G network in Indonesia. According to local press reports, KemKominfo spokesman Dedy Permadi confirmed that the mobile network operator (MNO) held a 5G Operation Feasibility Test (ULO) on 3-4 June using the 1800MHz band – unlike rival Telkomsel which recently launched 5G over its newly-acquired 2300MHz spectrum. Dedy stopped short of saying when Indosat Ooredoo will receive its 5G SKLO, however. TeleGeography notes that ULO testing is an important prerequisite to clear the path for the deployment of new technologies in Indonesia, carried out on the basis of Ministerial Regulation Number 1 of 2010 concerning the Operation of Telecommunication Networks. MNOs are required to complete ULO testing before securing approval for a commercial launch to the public.
