Apple released the second version of the public beta of iOS 26.3 on January 13, 2026. Esta update arrives just over a month after the first beta and incorporates internal changes that indicate significant advances in cross-platform messaging security. The main focus is on preparations to implement end-to-end encryption in the RCS standard.
The new beta files reveal specific references that allow operators to enable or disable the advanced encryption feature. Embora the functionality is not yet active for users, these codes represent a concrete step in the direction promised by the company months ago.
The final version of iOS 26.3 should reach the public in the coming weeks, possibly at the end of January or beginning of February. Até there, new intermediate betas should bring more refinements and possible activations of the feature.
Main indications in the new beta
Analysis of the codes from the second public beta highlights the inclusion of a sequence called “SupportsE2EE”. Essa reference allows operators to configure end-to-end encryption support directly on their networks.
The feature follows GSMA guidelines, which establish the default activation of encryption whenever local legislation allows. Apple adapts its implementation to meet these standards and ensure broad compatibility between devices.
- “SupportsE2EE” reference added in carrier bundles.
- Configuration allows activation or deactivation by region.
- Alignment with the RCS universal profile version 3.0.
- Mandatory user notification of encryption status.
Context of RCS support by Apple
The company introduced basic support for RCS starting with iOS 18, gradually replacing the old SMS/MMS in conversations with Android devices. Naquela initial phase, messages gained features such as sending high-resolution media and typing indicators, but remained without complete encryption.
The lack of end-to-end protection generated criticism, as conversations were vulnerable to interception by operators or third parties. The new preparation in iOS 26.3 resolves this limitation and brings RCS security on par with the existing iMessage standard between iPhones.
The advancement also responds to the standardization completed by the GSMA in March 2025. Desde then, manufacturers and operators work to implement interoperable encryption on a global scale.
Features retained from the first beta
The second public beta preserves the new features introduced in the previous version. One of them facilitates the transfer of data from an iPhone to Android devices, simplifying migration between platforms.
Another update has revamped the wallpaper gallery, offering reorganized options and additional high-quality images. Users report more intuitive access to the system’s native collections.
Furthermore, an exclusive function for União Europeia related to forwarding notifications remains active. Essa tool meets the requirements of Lei of Mercados Digitais and allows greater control over application alerts.
How to install the public beta
Interested users can participate in the Apple public testing program at no additional cost. The process requires prior registration on the company’s official website and compatibility with models starting from the iPhone XR.

Benefits of Cryptography in RCS
Full implementation of end-to-end encryption ensures that only the sender and recipient access the content of messages. Arquivos, photos and videos sent also receive the same protection.
This level of security prevents operators or intermediary providers from reading conversations. The measure increases privacy in cross-communications between iOS and Android.
European users additionally benefit from stricter data protection rules. The combination reinforces trust in the Apple messaging ecosystem.
Simplified transfer between platforms
The new migration option for Android appears at specific times during the device setup. Ela guides the user through clear steps to export contacts, messages and photos.
The process uses direct connection or cloud services to maintain data integrity. The tool reduces common barriers in ecosystem switching and facilitates purchasing decisions.
Visual updates to the system
The wallpaper gallery gained more organized categories in the first beta and maintains this structure. Novos Dynamic and static backgrounds complement the default options.
Users can preview images in full screen before applying. The selection includes seasonal and abstract themes regularly updated by Apple.
Regional features at União Europeia
EU-only notification routing allows you to redirect alerts between supported devices. The function meets regulatory obligations and improves the experience in mixed ecosystems.
It only operates in territories covered by Lei of Mercados Digitais. Fora of this region, the feature remains disabled by default.
Next steps in the beta cycle
Apple usually releases several intermediate versions before the stable release. Cada a brings bug fixes, performance improvements and security tweaks.
Developers and public testers continue to report feedback directly to the company. Essas information guides final changes before general release.
The current cycle suggests that the definitive version will arrive soon. Usuários outside the beta program will receive the update automatically via the stable channel.
