Apple’s latest iOS 26.3 beta 2 reveals a hidden carrier‑bundle setting that could enable end‑to‑end encryption (E2EE) for Rich Communication Services (RCS) messages. The tweak appears only in code for the four major French carriers—Bouygues, Orange, SFR, and Free—suggesting a regional rollout that aligns with the GSM Association’s recent standardization of E2EE for RCS. While the GSMA mandates that RCS clients enable encryption by default, local regulations can override that rule, and the new setting would let carriers toggle the feature on or off for all users in a market. Apple’s move follows a March announcement that it would support E2EE, but a year of silence left the timeline unclear.

The presence of the code now hints that the feature may arrive sooner than expected, potentially giving iPhone users a secure messaging option that rivals iMessage’s own encryption. As carriers prepare to comply, the next iOS release will likely decide whether the change becomes live.
