Esia

PT Bakrie Telecom Esia, operating in Indonesia (Oceania), was a telecommunications provider utilizing CDMA technology. Identified by the Mobile Country Code (MCC) 510, denoting Indonesia, and the Mobile Network Code (MNC) 99, Esia carved out a unique position in the competitive Indonesian mobile market. Unlike the GSM networks prevalent at the time such as Telkomsel or Indosat Ooredoo, Esia focused on providing affordable calling plans, particularly targeting lower income segments of the population with its "Esia Murah" (Esia Cheap) offerings. Esia’s strategy centered on a smaller geographic footprint compared to its GSM counterparts, concentrating on Java and other key islands. This allowed them to offer highly competitive local call rates. Though ultimately sunsetting its CDMA services, Esia's impact is remembered. Its pioneering efforts in affordable mobile communication influenced the Indonesian telecom landscape, demonstrating that tailored services addressing specific segments could thrive, even against larger national competitors. The 510 99 MCC/MNC remains a historical marker of this innovative, albeit now defunct, network.
