The update is available through Apple’s developer beta channel, and you can install it from the Software Update screen once your iPhone is enrolled.
How to update to iOS 26.3 beta 2

Changes in iOS 26.3 beta 2
Apple’s rollout notes for beta 2 focus on the new build rather than a headline feature drop. Reports so far have not flagged major new user-facing additions in this beta.
What remains central to iOS 26.3, based on what surfaced starting with beta 1:
- Transfer to Android tool: A setup-time transfer flow that helps move data from an iPhone to an Android phone without requiring a separate app.
- Wallpaper updates: Changes to the wallpaper gallery organization and new weather-related options reported in the first beta cycle.
- EU notification forwarding interface changes: A reported UI update tied to interoperability requirements in the EU.
