What to know

  • Turning off RCS on iPhone disables enhanced messaging features.
  • Users revert to standard SMS/MMS for non-iPhone conversations.
  • Some advanced functions like read receipts and typing indicators are lost.

Rich Communication Services (RCS) is a modern messaging protocol that Apple has introduced in iOS 18. When you turn off RCS on your iPhone, several changes occur in how you communicate with non-iPhone users. Here’s a brief on what you stand to lose with RCS turned off on your iPhone.

Reverting to SMS/MMS

The most significant change is that your iPhone will revert to using SMS and MMS for conversations with Android users. This means you’ll lose access to the enhanced features that RCS provides.

Loss of Advanced Features

By disabling RCS, you’ll no longer have access to read receipts when messaging Android users. This means you won’t be able to see when your messages have been read. Additionally, typing indicators will no longer be visible, so you won’t know when the other person is composing a message.

Media Quality Reduction

One of the benefits of RCS is the ability to send high-quality photos and videos. When you turn it off, you’ll be limited to the lower quality media sharing capabilities of MMS. This can result in compressed or pixelated images and videos.

Group Chat Limitations

RCS allows for improved group messaging experiences. Without it, you may face limitations in group chats with Android users, such as reduced participant limits or the inability to name group conversations.

No Wi-Fi Messaging

RCS allows messaging over Wi-Fi, which can be useful when cellular signal is weak. Turning it off means you’ll need cellular connectivity to send SMS/MMS messages to non-iPhone users.

Encryption Changes

RCS messages are typically encrypted. By turning it off, your messages to Android users will no longer have this added layer of security.

Impact on Battery Life

SMS/MMS can sometimes use more battery power than RCS, especially when sending media. You might notice a slight change in battery consumption when reverting to older messaging protocols.

Carrier Charges

Depending on your cellular plan, you might incur additional charges for SMS/MMS messages, especially when sending to international numbers, which RCS could have sent over data.

User Experience

Overall, turning off RCS will result in a less seamless messaging experience when communicating with Android users. The conversation will feel more disjointed compared to the smoother RCS or iMessage experience.

What doesn’t change when you turn off RCS on iPhone

While turning off RCS on iPhone changes how you get to interact with Android users, some things remain the same. These include the following:

  • iMessage functionality: Communication with other iPhone users through iMessage remains unaffected.
  • SMS/MMS capability: Your ability to send and receive standard text and multimedia messages is preserved.
  • Contact list: Your contacts and their information stay intact.
  • Message history: Previously sent and received messages are not deleted or altered.
  • Phone number: Your phone number associated with messaging remains the same.
  • Cellular network connectivity: Your ability to connect to your cellular network is not impacted.
  • App interface: The general layout and design of the Messages app stays the same.
  • Notifications: You’ll still receive notifications for incoming messages as usual.
  • Group chats with iPhone users: Existing group conversations with other iPhone users continue to function normally.
  • Emoji and sticker support: The ability to use emojis and stickers in messages is retained.
  • Message search functionality: You can still search through your messages as before.
  • Message forwarding: The option to forward messages to other contacts remains available.
  • Ability to block contacts: Your settings for blocked contacts are not affected.
  • Integration with other iOS features: Functions like sharing content from other apps via Messages remain operational.

These aspects of your iPhone’s messaging system continue to work as they did before, ensuring that basic communication functions are maintained even when RCS is turned off.

It’s important to note that you can easily re-enable RCS at any time by going back to your iPhone’s settings. This will restore all the advanced messaging features for conversations with Android users.
