A. Phone Spam Reporting 2026: Eligibility and Changes

You can report voice spam to KISA from A. Phone. SK Telecom subscribers can use the feature regardless of device type. Subscribers to other carriers can use it on Android. When you file a report, the call recording, caller’s number, and other information are submitted.

The start date and availability of the reporting feature are based on KISA’s October 12, 2026 announcement.

What Changed with Voice Spam Reporting Integration

This change adds a way to report spam to KISA from a carrier’s phone app. The existing simple reporting feature was available in the default phone app on Samsung Electronics devices. Using a carrier’s phone app limited access to that feature. The change is described in the KISA press release.

The reporting feature became available on September 30, 2026. The announcement date stated in the press release is October 12, 2026. The webpage shows a posting date of October 8, 2026. The posting date should not be mistaken for the service start date.

Suspicious voice spam can be reported to KISA through A. Phone.

A. Phone Availability by Carrier and Device

Availability depends on both the subscriber’s carrier and operating system. KISA said SK Telecom subscribers are supported regardless of device type. For subscribers to other carriers, it specified Android.

However, subscribers to other mobile carriers can use this feature only on Android.

The source is KISA’s press release, “Korea Internet & Security Agency and SK Telecom Reduce Blind Spots in Voice Spam.”

The announcement does not list support conditions for individual MVNOs. It is therefore difficult to determine availability from the network provider alone. Check whether your line is supported through the app’s customer support.

The App and Menu to Check on iPhone

The reporting menu on iPhone is described as part of the phone feature in the A. app. SK Telecom’s official website also directs iPhone users to the A. app for call recording. Checking only whether a separate A. Phone app is installed may cause confusion.

The A. App Store update notes give the location of the reporting menu. You can find it in the More menu on the right side of the call summary detail screen. The menu is called “Report Voice Spam to KISA.” This route is described in the developer’s update notes.

A. Phone Spam Reporting Process and Submitted Information

To file a report, identify the call in your recent call history. KISA says there is no need to write a separate description. The steps in the announcement are as follows.

1. Select the call you want to report from your recent call history.
2. Review the recording of that call.
3. Tap “Report Spam and Block.”

Be aware that the conversation, not just the number, is transmitted when you file a report. Check the app’s reporting screen for the full list of information sent. Check the relevant privacy notice for the retention period and how the information is handled.

The Difference Between Reporting, Number Ratings, and AI Detection

Reporting and risk detection serve different purposes. Number ratings display information left by other users. AI detection alerts users to potentially risky situations. A KISA report submits information to the agency for its response.

Safe Call provides a way to correct incorrectly displayed number information. You can also request deletion of information about your own number or cancel a rating you submitted. These options are described by the Safe Call Center.

This distinction means you should check AI warnings and report completion separately. There is no basis for assuming that canceling a number rating also cancels a report submitted to the agency. The features handle different information and use different submission channels.

Common Misconceptions About Report Data and AI Processing

Where AI processing takes place is separate from whether report data is transmitted. The A. developer notes describe some voice phishing detection as processing that takes place on the device. By contrast, call recording files and other information are submitted with KISA reports. The two descriptions refer to different processes.

• Using on-device AI detection does not mean report data also stays only on the device.
• Sending a recording with a report does not mean every call is submitted automatically.
• This announcement does not confirm whether report data is used to train AI.
• The absence of an AI warning does not establish that a call is safe.

This interpretation treats detection and reporting as separate functions. KISA says it analyzes reports and uses them to respond to spam. That statement should not be taken as consent to train a specific AI model.

Requirements for Call Recording, Summaries, and Other Features

A. Phone is not an app solely for reporting spam. Based on the former T Phone, it offers call management and AI features. The availability of the reporting feature, however, cannot be assumed to apply to other features.

Recording, summary, and interpretation requirements for the Android app are in the Google Play developer information. For iPhone calling features, also check the A. app information. The ability to install an app should be distinguished from the ability to use a particular feature.

baro Call is also separate from this reporting integration. Conditions such as enrollment in a data roaming plan apply. If the connection is poor, standard roaming voice call charges may apply. You can check the charges in T world’s baro Call information.

Status of Expansion to Other Carriers’ Apps

Integration with KT and LG Uplus AI phone apps is planned. This announcement does not mean reporting features have already launched in those apps. It also gives no specific start date.

This is separate from subscribers to other carriers using A. Adding a reporting feature to another company’s phone app is a separate task. Check KISA and each carrier’s announcements for updates.

Key questions in this article

Is voice spam reporting unavailable on iPhones?

It depends on the reporting route. This integration supports iPhone use by SK Telecom subscribers. Separately, KISA’s simple illegal spam reporting app also supports iOS. The limitations of the existing device-based simple reporting feature are explained in KISA’s reporting guide.

Where should I look if there is no recording?

You can check KISA’s separate reporting guide. This announcement describes a process in which you review a recording before submitting a report. It does not specify how the app handles calls without recordings.

Are all unknown numbers illegal spam?

An unfamiliar number is not, by itself, illegal spam. KISA’s spam guidance covers commercial advertising messages. Whether something is illegal depends on whether it violates the relevant rules.

Does filing a report immediately block the caller’s number for everyone?

This announcement does not guarantee immediate blocking for everyone. KISA says it analyzes reports and uses them for measures such as blocking numbers. Blocking in the app should not be treated as the same thing as the agency’s response.

Where can I check my report and its outcome?

KISA has a results menu on the Illegal Spam Response Center website. Go to “Illegal Spam > Spam Report Results” on the website. A number being blocked in the app alone does not mean the agency has finished processing the report.
