XLSmart

PT XLSmart Telecom Sejahtera Tbk (stylized in all-caps as XLSMART), formerly PT Excelcomindo Pratama Tbk and PT XL Axiata Tbk, is an Indonesian mobile telecommunications services operator headquartered at Jakarta, jointly owned by Malaysia-based company Axiata and Indonesian diversified conglomerate Sinar Mas. It is the third largest mobile telecommunications company in Indonesia. The operator's coverage includes Java, Bali, and Lombok as well as the principal cities in and around Sumatra, Kalimantan and Sulawesi. XLSmart offers home and mobile communication broadband services through their 2G GSM, 4G LTE, 5G NR and optical fiber network infrastructure under the three core brands: XL, Axis and Smartfren.

Initially, XLSmart provided cellular mobile telephony services using the GSM 900 technology. A few years after launching services, the company was awarded a license for implementing a DCS 1800 network, and to operate an ISP and VoIP service. In 2006, XL obtained a 3G license, which services launched in September of the same year.

At the end of 2010, the company had more than 22,000 BTS towers across Indonesia. It is the second largest mobile network operator in Indonesia, with a subscriber's strength of 55.1 million users.

Shares of XL surged in May 2019, one day after Axiata announced talks with Norway's Telenor aimed at combining their Asian operations.
