The iOS 26 Beta Profile is a small configuration file provided by Apple (and delivered by authorized sources like ios19beta.com) that allows any compatible iPhone or iPad to receive beta versions of iOS 26 “over the air.” Once you install this profile, you unlock instant access to all pre-release iOS 26 Beta updates directly in your device’s Settings app—just like you would with any official update.
Whether you’re a developer, a power user, or just someone who wants to see the future of Apple, downloading the iOS 26 Beta Profile is the only official way to become a beta tester and get iOS 26 Beta without a developer account.
