The company has to date deployed more than 4,500 base stations in Sumatra, Java, Kalimantan, Sulawesi, Bali, Nusa Tenggara, and Papua.
According to the operator, 4G subscriber take up is strong. The company has around 5 million 4G subscribers, and is aiming for 12 million by the end of the year.
The latest city to be covered by Telkomsel’s LTE rollout is Ambon in the Maluku province. The company has established 29 base stations in the seaport city, and aims to roll out 373 in the Maluku region.
Telkomsel’s current focus is on expanding its LTE network in the ‘buffer zones’ of Jakarta and Bandung, the company revealed.
Telkomsel was Indonesia’s first mobile operator to launch LTE services in late 2014, using the 900-MHz band. The company – along with its four major rivals – also launched LTE over the 1800-MHz band in July last year.
