Amid rising digital crime and the increasing volume of harmful spam calls and messages, Indosat Ooredoo Hutchison (Indosat) has reinforced its commitment to safeguarding customers through the integration of AI across its network.
Since its launch on 7 August 2025, Indosat’s Anti-Spam and Anti-Scam feature has blocked over 200 M risky calls, alerted users to more than 90 million suspicious messages, and protected an average of 11.5 M customers per month from potential digital fraud.
This innovation forms part of Indosat’s AIvolusi5G journey, a synergy between AI and 5G network capabilities, designed to deliver a digital experience that is secure, inclusive, and empowering. Operating at the network level, the system screens suspicious calls and messages automatically, without requiring additional apps or special devices.
Urgency for this protection is underscored by the GASA State of Scams in Indonesia 2025 report released in late August. The report found that 66% of Indonesian adults encountered scam attempts in the past year, with 14% losing money totaling IDR49 T. Most scams occurred via direct-message platforms such as instant messaging and SMS.
Bilal Khazmi, Director and Chief Commercial Officer, Indosat Ooredoo Hutchison said: “This technology is designed to help our customers of all age groups explore the digital world with greater confidence. With fast connectivity, accessible products, and strong protection, we remain committed to deliver world class digital experiences, connecting and empowering every Indonesian."
Based on internal data, more than 290 M spam calls have been identified on Indosat's VoLTE network. When extrapolated to the entire customer base, this figure amounts to over 500 M identified scam and spam SMS and calls within just 2.5 months since the launch of the Anti-Spam and Anti-Scam feature. In addition, more than 145 M spam and scam messages have been flagged, including 110 M scam (fraudulent) messages.
Although the system does not yet fully block harmful calls or messages, its role as an early-warning system has proven effective in reducing financial losses and strengthening public digital awareness, Indosat said. Customers receive alerts before potential harm occurs, enabling them to take timely preventative action.
Indosat believes that technological progress must go hand-in-hand with digital literacy enhancement. Guided by the Zero Trust principle — never assume trust, always verify — this principle forms the foundation of Indosat’s approach in introducing this feature, helping the public remain vigilant toward suspicious messages, links, and calls.
The Anti-Spam and Anti-Scam feature, powered by Indosat’s AIvolusi5G technology, provides protection without requiring premium devices or additional app installations. For IM3 mobile customers, this protection is introduced as SATSPAM (Satuan Anti Scam dan Spam). SATSPAM BASIC is automatically active for all IM3 prepaid users with an active data package, and SATSPAM+ offers enhanced protection with the ability to detect malicious links.
Tri mobile customers have a similar feature called TRI AI. AntiSpam/Scam features are available through visual detection with three colour codes: turquoise for a safe number, yellow for an unknown number, and red for high-risk numbers.
Customers from IM3 and Tri can also access the Plus+ protection feature through the myIM3 and bima+ apps. This feature is automatically activated for users with an active data package, providing alerts via phone notifications and SMS for numbers flagged as suspicious or potentially harmful. It also offers clearer SMS warnings, colour-coded notification popups, and a call history summary accessible directly through the apps.
