Enabling and using RCS on iOS 18 iPhones

iOS 18 brings a game-changing feature to iPhones: Rich Communication Services (RCS). This advanced messaging protocol enhances your texting experience with non-Apple devices and other iPhones, appearing as green bubbles in the Messages app. Here’s a comprehensive guide on activating and utilizing RCS on your iPhone.

Prerequisites

Before proceeding, ensure you have:

  • An iPhone running iOS 18 or newer
  • A cellular plan from an RCS-supporting carrier
  • A reliable internet connection

Activating RCS

To enable RCS on your iPhone, follow these steps:

  1. Navigate to the Settings app
  2. Scroll and select “Apps”
  3. Locate and tap “Messages”
  4. Find the “RCS Messaging” option
  5. Flip the switch next to “RCS Messaging” to activate it

Leveraging RCS features

With RCS activated, you can enjoy these enhanced messaging capabilities:

  • Green bubble conversations in the Messages app
  • Sharing of high-quality photos and videos
  • Sending rich media content and links
  • Viewing delivery and read receipts
  • Observing typing indicators as others compose messages

Key considerations

Keep these important points in mind:

  • RCS messages lack end-to-end encryption
  • Your carrier may use identifiers like IMEI, IMSI, IP address, and phone number for RCS setup
  • Your current IP address might be visible to other RCS users

Deactivating RCS

If you wish to turn off RCS:

  1. Go to Settings > Apps > Messages > RCS Messaging
  2. Toggle the switch to disable RCS Messaging

For any uncertainties about your carrier’s RCS support, reach out to them directly for clarification.
