WhatsApp Now Default App for Calls and Messages: What You Need to Know!

WhatsApp Becomes a Default App for Calls and Texts

As noted by WABetaInfo, the most recent update to WhatsApp Messenger for iPhone finally allows users to select the app as their default messaging or calling client. Once enabled in the system settings, any interaction with a phone number or contact link (e.g., via Safari, Contacts, or Maps) will use WhatsApp instead of the built-in iOS Phone or Messages app.

This shift is part of a broader evolution of Apple’s mobile system, which began with iOS 14 for browsers and mail clients, and expanded with iOS 18.2 to include other application categories. This move primarily showcases a strong push towards interoperability. Although this opening was initially prompted by the requirements of the DMA (Digital Markets Act) in Europe, Apple has decided to extend it to all users, regardless of their location.

As of now, iOS 18.2 allows setting third-party apps as defaults for the following uses:
• Phone Calls
• SMS/Messages
• Web Browser
• Email
• Translation
• Payment (in certain regions)
• Password Manager
• Keyboard
• Call Filtering
• Mapping (EU only)

How to Set WhatsApp as Your Default for Calls and Messages?

To do this, you need to have the latest update of WhatsApp, which is available to all users, including those outside of beta programs. This integration paves the way for a smoother use of WhatsApp within the iOS ecosystem, while offering more choices to users in customizing their mobile experience.

To enable WhatsApp as your default app:

1. Go to Settings > Apps > Default Apps
2. Select WhatsApp for calls and/or messages
