  • End-to-end encryption (E2EE) for RCS messaging between iPhone and Android users is coming soon via the new Universal Profile 3.0 specifications from GSMA.
  • The new standard supports the Messaging Layer Security (MLS) protocol, which enables interoperable E2EE across different client implementations, improving security.
  • Apple has committed to incorporating the new standard in future software updates, so we’ll still have to wait for adoption.

iPhone users finally got to take advantage of RCS texting with the release of iOS 18. RCS allows iPhone users to seamlessly text Android users with high-quality media, text reactions, richer group chats, and more. However, RCS conversations between iPhone and Android users come with a big caveat — the lack of end-to-end encryption. This will soon be fixed, as RCS end-to-end encryption is coming soon to iPhones, fixing the encryption oversight in iPhone-Android RCS conversations.

GSMA has announced new Universal Profile 3.0 specifications for RCS that include end-to-end encryption (E2EE) based on the Messaging Layer Security (MLS) protocol. GSMA says that this will make RCS the first large-scale messaging service to support interoperable E2EE between different client implementations.
