Indosat announced that since its launch on 7 August 2025, the company’s Anti-Spam and Anti-Scam feature has blocked over 200 million risky calls, alerted more than 90 million suspicious messages, and protected an average of 11.5 million 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 seamlessly 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 recorded that 66% of Indonesian adults encountered scam attempts in the past year, with 14% losing money totaling IDR 49 trillion (US$3.3 billion). Most scams occurred via direct-message platforms such as instant messaging and SMS. Furthermore, 51% of Indonesian adults who fell victim to scams stated that the experience caused them stress.
Based on internal data, more than 290 million spam calls have been identified on the VoLTE network. When extrapolated to the entire customer base, this figure amounts to over 500 million 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 million spam and scam messages have been flagged, including 110 million 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. 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 comprehensive protection without requiring premium devices or additional app installations. Through IM3, this protection is introduced as SATSPAM (Satuan Anti Scam dan Spam), which comes in two types: SATSPAM BASIC, automatically active for all IM3 prepaid users with an active data package, and SATSPAM+, which offers enhanced protection with the ability to detect malicious links.
For Tri customers, a similar feature called TRI AI: AntiSpam/Scam is available through visual detection with three color codes: turquoise for Safe Number, yellow for Unknown Number, and red for High-Risk Number. On top of that, 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, color-coded notification pop-ups, and a call history summary accessible directly through the apps.
With the support of continuously advancing AI technology and ongoing cybersecurity education initiatives, Indosat reinforces its commitment not only to protect customers from digital threats but also to build public trust and resilience in an era of unlimited connectivity. This initiative is aligned with the company’s mission to deliver world class digital experiences, connecting and empowering every Indonesian.
