You Can Now Make WhatsApp Your Default Calling App on iPhone — Here's How

The latest iOS 18.2 update has brought a major shift for WhatsApp users on iPhone, finally allowing the messaging giant to function as the default calling app. While the January 2025 update initially flew under the radar, its ability to integrate third-party apps like WhatsApp into Apple’s tightly controlled ecosystem marks a significant change for millions of users.

For years, Android users have enjoyed the flexibility of setting default apps for calls, messages, and emails—a feature long restricted on iPhones due to Apple’s closed-system approach. However, with iOS 18.2, Apple has loosened its grip, letting iPhone users bypass the native Phone app in favor of WhatsApp for calls.

How to Set WhatsApp as Your Default Calling App on iPhone
Follow these simple steps to make the switch:

• Open Settings on your iPhone.
• Scroll down and tap on Apps.
• Select the Default Apps tab at the top.
• Choose Calls from the list of options.
• Select WhatsApp from the menu.

Once enabled, all call prompts will automatically redirect to WhatsApp, streamlining communication for users who rely on the app for voice and video calls.

This move aligns with WhatsApp’s push to dominate the calling space, introducing features like enhanced video meetings and cross-platform compatibility—advantages that many competitors still lack.

Since the iOS 18.2 update is already live, most recent iPhone models support this feature, giving users long-awaited freedom in app preferences. Will this be the start of Apple embracing more third-party defaults? Only time will tell.
