Apple’s recent announcement at the Worldwide Developers Conference revealed an exciting update set to roll out this fall: iOS 26. This upcoming release will introduce a striking new Liquid Glass design along with features like call screening. But before we dive into what’s new, let’s not overlook the impact of iOS 18, which debuted in 2024 and brought with it the Rich Communication Services (RCS) protocol to all iPhones.
The inclusion of RCS messaging allows users to enjoy typing indicators and “Delivered” statuses while communicating with Android users. More importantly, it ensures that high-quality videos and images are shared seamlessly across devices. With the introduction of iOS 18.1, Apple even enhanced the experience by integrating RCS Business Messaging, allowing customers to converse with brands directly through Messages instead of clunky websites.
However, a significant limitation exists: RCS on iPhone does not yet provide end-to-end encryption between iPhone and Android devices. Fortunately, the GSM Association is actively working on establishing encrypted messaging, and with insights from Android Authority, we could see these enhancements in iOS 26.
Checking RCS Support on Your Carrier
While most major carriers support RCS, it’s essential to verify your own. For instance, AT&T, T-Mobile, and Verizon have confirmed RCS compatibility for iPhones running iOS 18.6.1. Here’s a list of US carriers that support RCS:
- AT&T
- C Spire
- Consumer Cellular
- Cricket
- Family Mobile
- FirstNet
- H20 Wireless
- Metro by T-Mobile
- PureTalk
- RedPocket Mobile
- Spectrum Mobile
- T-Mobile
- TracFone / Straight Talk
- Ultra Mobile
- US Cellular
- Verizon
- Visible
- Xfinity Mobile
If you’re outside the US and wondering about your carrier’s support for RCS messaging, follow these steps on your iPhone:
1. Open Settings.
2. Tap General.
3. Tap About.
4. Tap Carrier.
In this section, you’ll see IMS Status that indicates your messaging support. If your carrier enables RCS, it will say Voice, SMS & RCS. No support will show as Voice & SMS.
Enabling or Disabling RCS on Your iPhone
If RCS is supported by your carrier, here’s how to turn it on:
1. Open Settings.
2. Tap Apps at the bottom of the menu.
3. Tap Messages.
4. Tap RCS Messaging under Text Messaging.
5. Toggle the switch next to RCS Messaging.
This will allow you to message Android users more similarly to texting another iPhone, although you’ll still see those recognizable green bubbles. Should you need to disable it, just follow these steps again.
Troubleshooting RCS Issues
If you’ve updated to iOS 18.6.1, confirmed RCS support from your carrier, and enabled it, but it’s still causing trouble, a quick restart of your iPhone might do the trick.
Is Messaging Android Devices Safe?
While it’s generally safe, using a messaging app with end-to-end encryption, like Signal, is recommended. Currently, RCS on iPhone lacks this crucial security feature. In light of recent cyberattacks targeting telecom networks, users of both platforms should remain cautious about communications. The GSMA plans to enhance RCS with interoperable encryption, enabling secure messaging across different carriers. An Apple official confirmed that end-to-end encrypted messages will be integrated into upcoming updates for iOS, iPadOS, MacOS, and WatchOS.
According to developments cited by Android Authority, initial codes in the iOS 26 beta hint at a long-awaited introduction of end-to-end encryption for Messages this fall. This would mark a significant upgrade for user privacy and security.
For enthusiasts anxious about changes, checking internal updates like the iOS 18 and iOS 26 releases will offer insights into new features and improvements.
