How to Turn Off RCS Messaging? A Step-by-Step Guide

Q: Should I Turn Off RCS Messaging?

Turning off RCS messaging is advisable if you want to send only regular SMS or get a new phone. Doing so prevents you from potential messaging issues from your previous device.

Q: Is RCS the Same as SMS?

SMS can only send text messages up to 160 characters and doesn’t support multimedia sharing. However, RCS helps overcome these limitations by providing rich communication features, including read receipts.

Q: Can You Delete RCS Messages?

You can delete the entire conversation using RCS, as there is no option to “delete for me” or “delete for everyone” like WhatsApp.

Q: What happens if I turn off RCS on my iPhone?

Turning off RCS on an iPhone will disable chat features and revert messaging to SMS or MMS. This helps prevent delivery delays when switching phones or SIM cards, especially if your carrier no longer supports RCS.

Q: Why is my phone using RCS instead of SMS?

Your phone may default to RCS if both sender and recipient have RCS enabled and are using compatible apps like Google Messages. You can disable RCS in your messaging settings to revert to SMS.

Q: Can I use RCS without an internet connection?

No, RCS requires an active internet connection. Without mobile data or Wi-Fi, RCS messages cannot be sent or received. In such cases, messages will default to SMS or MMS if supported by the device and carrier.

People use billions of texts to communicate with others each year. While traditional SMS (Short Message Service) and MMS (Multi Media Message) were the standard for years, RCS (Rich Communication Services) messaging emerged as an advanced messaging protocol replacing both.

RCS offers features like read receipts, high-quality images and video sharing, typing indicators, and the ability to send larger files. Though it has advanced functionality, some users may want to avoid using RCS as it uses too much data, does not work well with all phones, and lacks privacy.

Turning RCS messaging off can be confusing, but it isn’t as complicated as you think. You can easily disable RCS on your device by navigating and taking the proper steps through the phone's messages settings.

What is RCS Messaging?

Rich Communication Services (RCS) is a messaging protocol that upgrades traditional SMS by allowing users to send high-resolution images, videos, read receipts, and real-time typing indicators using mobile data or Wi-Fi. Now with billions of active users monthly, RCS is supported on both Android (Google Messages) and iOS devices.

RCS messaging also allows users to see typing indicators, send and receive high-quality media, and create group chats, including read receipts (sent, delivered, and read status). The GSM Association (GSMA) first developed RCS messaging in 2007 and introduced it in 2008. The basic idea behind its development was to replace SMS and MMS in cellular networks with more modern features.

RCS messaging has been on Android mobile for a long time. However, Apple recently started supporting it in messages, i.e., in September 2024. Users can also access RCS through their desktops via a Microsoft Phone link or as a web client of Google Messages.

Why to Turn Off RCS Messaging?

Device incompatibility, dependency on carrier networks, and security concerns are the main reasons you should turn off RCS messaging on your device. Turning it off can improve message reliability, protect your privacy, and ensure smooth communication across different devices.

Device Incompatibility

Unlike SMS and MMS, RCS isn’t compatible with all devices. Even though RCS now comes preinstalled on recent mobile phones, not all previous devices support it. On iPhones, it requires iOS version 18 or above, and on others, Android version 5 or higher on others. So, while messaging the older phones, RCS messaging won’t work.

Cost

While most carriers offer free SMS services with their mobile plans, SMS can be effective. On the other hand, if you do not purchase an unlimited data plan, RCS can be costlier to use due to its rich features. Individuals or smaller businesses with tight budgets may want to reduce the use of RCS.

Depends on Carrier Networks

Even though RCS messaging is gaining widespread popularity, one of the main concerns is carrier network support. While many have implemented RCS, some carrier services still don’t support it. This limits its reach, and users may want to turn it off.

Security

RCS messaging is more secure than traditional SMS and MMS but still poses security threats. Because of its rich features, it is more complex and may attract more threats, such as phishing attacks. So, users should always be observant and must take appropriate measures to protect their personal information.
