WhatsApp Can Now Be Set as Default Calling and Messaging App on iPhone

Apple’s iOS 18.2 Update Brings More Freedom to Users

With the release of iOS 18.2, Apple has introduced a long-awaited feature: the ability to set third-party apps as default for calls and messages. This marks a significant shift in Apple’s ecosystem, allowing users to bypass the built-in Phone and Messages apps in favor of alternatives like WhatsApp.

Now, WhatsApp has officially rolled out support for this feature, giving iPhone users the option to make it their default app for both calling and texting. This update not only enhances user convenience but also aligns with regulatory changes pushing Apple toward a more open system.

Set WhatsApp as Your Default Calling and Messaging App

According to reports from WABetaInfo, the latest version of WhatsApp for iOS now supports Apple’s new default app API. When a user sets WhatsApp as their preferred app, any action related to calls or messages—such as tapping a phone number—will automatically launch WhatsApp instead of Apple’s built-in apps.

This feature was initially developed in response to regulations from the European Union, which has been pushing for greater competition and user choice within Apple’s ecosystem. However, Apple has opted to make the functionality available worldwide, not just in the EU.

Expanding Default App Choices on iOS

Beyond calls and messages, iPhone users can now customize other default apps, including:

Email: Set a preferred email client instead of Apple Mail.
Web Browsing: Choose third-party browsers like Chrome or Firefox.
Call Filtering: Use specialized apps for spam detection.
Translation: Opt for alternative translation services over Apple’s built-in solution.
Passwords & Payments: In select regions, users can set third-party apps for managing passwords and payments.
Keyboards & Maps: EU users even have the option to change their default maps app.

WhatsApp Rolls Out the Feature to All Users

This new capability is no longer limited to beta testers—WhatsApp has officially rolled it out to all iPhone users. To enable the feature, make sure you’ve updated WhatsApp to the latest version available on the App Store.

This move further strengthens WhatsApp’s presence on iOS, making it even more central to communication for those who rely on the app for messaging and voice calls.

What Undercode Says:

Apple’s decision to allow third-party apps as defaults is a direct response to growing regulatory pressure, particularly from the European Union. The EU’s Digital Markets Act (DMA) has been a driving force behind Apple’s more open approach, pushing the company to ease restrictions on default apps, alternative app stores, and third-party payment systems.

This change represents a win for users who have long demanded more flexibility within Apple’s tightly controlled ecosystem. It also signals a shift in Apple’s strategy, acknowledging that competition and user choice are inevitable aspects of modern software platforms.

For WhatsApp, this is a strategic move that further embeds the app into users’ daily lives. By becoming the default calling and messaging option, WhatsApp strengthens its dominance as a primary communication tool, potentially reducing reliance on traditional phone networks and Apple’s iMessage system.

From a competitive standpoint, this update puts additional pressure on Apple’s own apps. iMessage, which has long been a key selling point for iPhones, could face declining usage as more people switch to WhatsApp as their default option. This could, in turn, push Apple to further enhance iMessage’s features to retain users.

However, there are still limitations. For example, while WhatsApp can now be set as the default app, Apple still controls deeper system-level integrations. Unlike Android, where users can fully replace system apps, Apple may still have underlying restrictions that favor its own services.

Additionally, this change could pave the way for other popular messaging and calling apps, such as Telegram and Signal, to introduce similar functionality. If they follow WhatsApp’s lead, users could have even more options to personalize their iPhone experience.

For now, this update is a major step in the right direction for user freedom on iOS, and it will be interesting to see how Apple continues to balance openness with its long-standing ecosystem control.
