Apple and Android users have been warned that end-to-end encryption for RCS is still months away and that they should use other chat apps to communicate.

One of the biggest changes brought by iOS18 is the integration of RCS into the iMessage app, making it easier than ever to connect with Android phones. However, one major problem is that communications between Apple and Android phones do not benefit from end-to-end encryption. This means that messages can be easily intercepted, and in recent events, major security organizations have warned users to look elsewhere.

More recently, the attack by Salt Typhoon, which compromised several major telecommunications carriers in one of the largest infrastructure attacks in U.S. history, highlighted the security problem. As a result, both the CSIA and the FBI urged U.S. citizens to use end-to-end encrypted chat applications when communicating. Meanwhile, the Global System for Mobile Communications (GSMA) is working on end-to-end encryption. However, a recent report to CNBC reveals that a solution is still a ways off. [A GSMA spokesperson told CNBC that “work with key industry stakeholders is progressing well and we look forward to providing an update to the market in the coming months. While it is good that a solution is underway, the lack of a clear timetable is concerning. Following this advice, users should probably use apps such as WhatsApp, Telegram, and Signal for the time being.

This is not the only security-related news that users should be aware of at present. For example, Apple users are being urged to update to iOS 18.2 to avoid a critical bug affecting the Apple Password app.

It is odd that Apple and Android devices still lack end-to-end encryption. Thankfully, all of the aforementioned apps work just fine. We have a complete breakdown of the best encryption apps to help you find the right one for you.
