Kaspersky Who Calls review
Caller ID, configurable spam blocking and Premium protections for Android and iOS.
Reviewed by iTechGuides Editors · Editorial team · Updated Oct 2026
Unknown calls are easier to assess with Kaspersky Who Calls, a mobile caller ID and spam-call detection app for Android and iOS. It shows caller identity, category and trust information, labels suspected spam, and can automatically block all spam calls or selected categories. Users can also submit numbers to spam lists, which may inform the online database. Its focus suits individual users who want caller context and configurable blocking on a phone, rather than a broader call-management system.
The free version is available indefinitely, with ads and fewer caller details. Premium adds offline caller information, additional blocking categories, outgoing-call protection, and warnings about dangerous, phishing and advertising links in SMS. Caller identification uses online databases, while offline information is a Premium capability. That makes the paid tier more relevant for users who want caller details without relying on an online lookup, as well as those seeking the added outgoing-call and SMS protections. The app also detects spam on WhatsApp calls.
Kaspersky Who Calls covers both major mobile platforms and combines caller identification with spam labels and user-submitted numbers. It is a sensible fit for someone who wants those functions together and values Premium’s offline caller information. It is less suitable for someone who wants an ad-free free version, or whose region does not support the app. The product is mobile-only, and its described support channel is documentation, so buyers who need a desktop option or a different support route should consider alternatives.
