WhatsApp will raise its requirements in 2026 and will stop supporting millions of phones. Starting January 1, 2026, Meta's instant messaging application will no longer be compatible with devices that do not meet minimum operating system versions, affecting users worldwide, especially in emerging markets like Latin America.

Minimum Compatibility Requirements

Android phones will require at least version 5.0 Lollipop or higher, excluding devices released before 2014 that are incompatible with updates. For iPhones, iOS 15.1 or later is required, excluding models that do not reach that operating system version.

For devices running KaiOS, such as some feature phones, the minimum version is 2.5.0, a measure designed to ensure advanced security and new features like improved encryption and artificial intelligence tools. This policy responds to the need to optimize resources and protect data in an ecosystem of growing cyber threats.

Devices affected by the change

Implications and practical recommendations

The change aims to strengthen privacy against vulnerabilities in outdated systems that do not support high-definition video calls or modern hacking protections. WhatsApp will notify affected users via in-app alerts, recommending backing up conversations to Google Drive for Android or iCloud for iOS before the phase-out. Users should check their version in Settings > About and attempt software updates; Otherwise, opt for devices with Android 10 or higher and recent iPhones to ensure future compatibility. In contexts where WhatsApp is essential for work and family communications, this transition accelerates device upgrades, with opportunities for year-end promotions.
