In a significant shift for iPhone users, WhatsApp can now be set as the default app for both calls and messages on iOS — a move that further strengthens its position as a global communications hub.
This update comes as part of Apple’s iOS 18.2 release, which introduces greater flexibility by allowing users to choose third-party apps — not just Apple’s native ones — as defaults for key functions such as messaging, calling, browsing, and email.
How It Works
Previously, iOS users were locked into using the Phone app and iMessage for default communication tasks. With this new policy change, they can now seamlessly initiate calls and send messages via WhatsApp, directly from the Contacts app or any screen where a phone number is tappable.
To activate the feature, users must:
- Ensure their iPhone is running iOS 18.2 or later
- Update WhatsApp to version 25.8.74 or higher
- Go to Settings > Apps > Default Apps
- Under both “Messaging” and “Calling,” select WhatsApp as the default
Once configured, actions like tapping a contact number will automatically launch WhatsApp for the interaction, eliminating the need to toggle between apps.
Privacy + Functionality: Why This Matters
WhatsApp’s integration as a default app goes beyond convenience. It brings with it:
- End-to-end encryption for all calls and messages, offering greater privacy protection than many default SMS or call apps
- Free international calling, which is especially useful for users with global connections
- Seamless media sharing, including documents, voice notes, and videos, within a familiar interface
This update is especially relevant at a time when users are increasingly concerned about data security and communication efficiency. Consolidating everyday conversations within a single, secure app reduces friction and strengthens digital privacy.
Currently in Beta, Wider Rollout Coming
As of now, the feature is available to TestFlight beta users and will be rolled out to the wider public in the coming weeks. Users eager to explore this functionality can join WhatsApp’s beta program or wait for the official release.
The Bigger Picture
This development reflects a broader shift in Apple’s approach to platform openness — likely influenced by increasing regulatory pressure from regions like the EU. For WhatsApp, it’s a strategic win that expands its reach beyond just chat, making it a centralized communication platform on devices traditionally dominated by Apple’s own apps.
As the mobile OS landscape evolves, such integrations signal a future where user choice, security, and cross-platform functionality take centre stage.
