Mobile network operator (MNO) Telkomsel has reportedly completed the process of transferring and upgrading all 3G users to 4G LTE in 504 cities/regencies across Indonesia.
The process began back in March 2022 and was ‘measurably completed’ in June 2023 by upgrading more than 49,000 3G base transceiver stations (BTS) to 4G BTS. As a result, the MNO states that more than 96% of the population is now blanketed by its LTE network.
