Spam Calls

Unsolicited calls have become a growing nuisance for mobile users in Indonesia, with many of them carrying online loan offers, gambling promotions, or scam attempts involving fake couriers and fabricated family emergencies. Beyond the annoyance, the problem has turned phone numbers into a gateway for privacy abuse and potential financial harm.The scale of the issue is closely tied to leaked data circulating in dark markets and to autodialer systems that can place calls in bulk at very low cost. Because caller identities can also be manipulated through spoofing, many of these calls are difficult to trace before they reach the user.Why the problem keeps spreadingSeveral factors have made Indonesia a prime target for spam telephony. Data leaks from digital platforms make phone numbers easier to obtain, while Voice over Internet Protocol or VoIP technology allows mass calling at minimal expense.Even with personal data protection rules now in place, the technical response to aggressive telemarketing is still evolving. In practice, users are left to rely on device-level protection and cautious habits when answering unfamiliar numbers.Android users can activate built-in spam filtersAndroid devices offer built-in tools that help screen suspicious calls and reduce repeated interruptions. The settings are designed to identify numbers commonly reported as spam and limit how often they reach the user.StepActionResult1Open the Phone appAccess call settings2Tap the three-dot icon and choose SettingsOpen configuration menu3Enter Caller ID & SpamFind spam protection options4Turn on See caller and spam IDDisplay caller and spam identification5Turn on Filter spam callsReduce spam call interruptionsFor numbers that keep calling, manual blocking is still available from the call history. Users can press and hold the number, then choose Block or Report Spam.iPhone users can silence unknown callersApple devices also include a practical option for limiting nuisance calls from unknown numbers. When enabled, the feature sends calls from numbers outside the contact list to voicemail without making the phone ring.StepActionResult1Open SettingsAccess phone controls2Select PhoneOpen call management menu3Find Silence Unknown CallersLocate blocking feature4Switch it OnSilence unknown numbersThose calls still appear in Recents, but the device will not ring. If a particular number remains disruptive, users can open Recents, tap the “i” icon, and select Block this Caller.Third-party apps add another layerCaller-identification apps can provide additional protection when built-in tools are not enough. Truecaller and Whoscall are two widely known options because they use community databases to help identify risky numbers.AppMain FeatureKey BenefitTruecallerAutomatic identification and blockingLarge global database and high accuracyWhoscallOffline database for identification without internetLightweight and effective for SMS spam filteringThese apps can be useful, but they often request access to contacts. That permission deserves careful consideration because it involves personal privacy and data handling.Privacy habits matter as much as blocking toolsNot every spam call can be stopped at the device level, so everyday caution remains important. Calls from foreign numbers are best ignored unless they are clearly linked to relatives or official matters, since they are often associated with Wangiri-style callback scams.Phone numbers should also be shared sparingly during online registration. Untrusted sites and social media quizzes often become channels for collecting data that can later be used for aggressive promotions or misuse.If a caller claims to represent a bank or a government institution, no OTP, PIN, or password should be disclosed. Sensitive information is not supposed to be requested by legitimate institutions over the phone.Reporting options and additional protectionSome mobile operators in Indonesia provide complaint channels for spam calls or SMS. The source material notes that certain operators accept reports through SMS to a specific short number, including 1166 in some cases.When the same number keeps appearing with a similar pattern, spam filters or caller-ID apps are usually more effective than blocking one number at a time. These systems can flag numbers based on call behavior and community reports rather than on a single incident.In the current environment, the strongest protection comes from combining device settings, careful sharing of personal data, and a skeptical attitude toward callers whose identities cannot be verified. That approach helps reduce spam calls without sacrificing convenience or privacy. Source: mediaindonesia.com
