Telkomsel

Indonesia’s three leading mobile players - Telkomsel, Indosat Ooredoo Hutchison (IOH), and XLSMART -have formed a joint Telco API Alliance to standardize network-exposed APIs and harden the country’s digital ecosystem against fraud. The alliance commits all three operators to a common telco API protocol aligned with CAMARA, the open-source, Linux Foundation–hosted API project supported by the GSMA Open Gateway initiative. The initial roll-out centers on customer protection and fraud prevention—areas where network signals offer high value. SIM Swap detection flags recent SIM changes, a leading indicator of account takeover risk.
