Muhammad Syarkawi Rauf, Chairman of the KPPU, informed that there are indications that both telecommunication operators - both listed on the Indonesia Stock Exchange (IDX) - are (1) coordinating to determine prices, (2) coordinating to divide geographical areas for their products, and (3) coordinating to restrict the output of their products. These allegations are the result of the establishment of their joint venture One Indonesia Synergy.

Turina Farouk, Vice President Corporate Communication of XL Axiata, said the company cannot respond yet to the KPPU's summon as XL Axiata is yet to receive the full details of the case. However, regarding One Indonesia Synergy Farouk said this joint venture is not a vehicle used to engage in cartel practices but is part of cost efficiency efforts for the development of their 4G LTE network. Farouk added that One Indonesia Synergy is not operational yet as it awaits several permits from authorities.

Cooperation is a strategy of Indosat Ooredoo and XL Axiata to make their operations more efficient in the future. Indonesia's telecommunication sector is dominated by state-controlled Telekomunikasi Indonesia.

Indosat Ooredoo and XL Axiata each own a 50 percent stake in joint venture One Indonesia Synergy. Alexander Rusli, President Director and CEO of Indosat, said One Indonesia Synergy will offer consultation services for both companies' cooperation in telecommunication networks, for example the so-called multi operator radio access network.
