How to Set WhatsApp as the Default Calling and Messaging App on iPhone

WhatsApp is one of the world's most widely used messaging and calling platforms. While Android users can easily set WhatsApp as their default app for calls and texts, iPhone users face more limitations due to Apple’s system restrictions.

But don’t worry—there are smart workarounds to make WhatsApp your go-to messaging and calling app on iPhone. This guide will show you how to maximize WhatsApp usage on your iPhone and make it feel like your default calling and messaging app.

Can you set WhatsApp as the default app on your iPhone?

Unlike Android, Apple does not officially allow third-party apps like WhatsApp to be set as the default app for phone calls or SMS. However, you can change your habits and use automation features to ensure WhatsApp becomes your primary communication tool.

Let’s explore the steps and alternatives.

1. Add WhatsApp Shortcut to Home & Dock

To access WhatsApp quickly:

• Tap and hold the WhatsApp icon
• Drag it to your iPhone Dock (bottom bar)
• Place it where your regular Phone or Messages app was

This makes WhatsApp just a tap away—just like a default app.

2. Use WhatsApp for All Contacts (From the Contacts App)

You can initiate WhatsApp calls and chats directly from your Contacts app.

Steps:

1. Open the Contacts app on your iPhone
2. Select a contact who also uses WhatsApp
3. Scroll down to see WhatsApp Call or WhatsApp Message
4. Tap the desired action to initiate communication via WhatsApp

You can edit their contact for frequent contacts and move WhatsApp options to the top for faster access.

3. Use Siri to Call or Message on WhatsApp

Apple allows Siri to work with WhatsApp.

Enable Siri Integration:

1. Go to Settings > Siri & Search
2. Scroll down to WhatsApp
3. Enable Use with Ask Siri

Now Say:

• “Hey Siri, send a WhatsApp message to [Contact Name].”
• “Hey Siri, call [Contact Name] on WhatsApp.”

This makes WhatsApp feel like your default calling/messaging app using voice commands.

4. Set WhatsApp as Default in Communication Apps (If Available)

In some apps like Google Assistant, contact managers, or CRM tools, you can set WhatsApp as your preferred method of communication.

Check app settings under:

• Default calling method
• Default messaging platform

5. Use Shortcuts Automation for WhatsApp

Create a Siri Shortcut to route specific contacts through WhatsApp only.

Steps:

1. Open the Shortcuts app
2. Tap + > Add Action
3. Search for Send Message via WhatsApp
4. Choose the contact and customize the message
5. Add to Home Screen for instant access

You can create a folder of WhatsApp-based contact shortcuts for faster communication.

6. Remove or Hide Default Phone & Messages App

If you don’t want to use the Phone or Messages app:

• Long-press the app > Tap Remove App > Select Remove from Home Screen
• Or move them into a hidden folder

This forces you to shift your habit to WhatsApp for all communication.

Important Notes

• iPhone still uses the default Phone and Messages app for system calls (emergency, unknown numbers, etc.)
• Missed calls and SMS will still be logged in their respective default apps
• WhatsApp requires an active internet connection for both calling and messaging

Conclusion

While iPhones don’t allow full default app changes like Android, there are multiple ways to make WhatsApp your primary communication app. With smart tweaks like Siri, Shortcuts, and Dock placement, you can turn WhatsApp into your go-to app for calling and texting.

By following the above steps, you’ll streamline your iPhone experience and enjoy faster communication through WhatsApp every time.
