It’s probably time we moved on from the old SMS standard
The RCS messaging protocol has been a long time coming. While iPhone owners have had interactive iMessages for years, Android users had to use third-party messaging apps for years, as carriers were slow to warm up to RCS. Google Messages' adoption of the RCS standard has made the app even better, as it lets you enjoy secure and interactive texting on your Android phone.
With RCS, Android's Messages app offers features like typing indicators, inline replies, group chats, video calls, and photo and video sharing. RCS messaging works on all Android phones, whether you're the proud new owner of a Google Pixel 8 Pro, or you're rocking a budget phone.
Rich Communications Services (RCS) is a communication protocol that will ultimately replace MMS and SMS messages on Android devices. Although the protocol was created in 2007, it failed to take off until recently.
Google worked closely with the GSMA, its members, and carriers around the globe to create a universal profile for RCS that uses Android's Messages client in 2019. Many Android users can use RCS Messaging now, but the messaging protocol isn't supported on iOS.
The RCS update offers a better overall messaging experience with features that are similar to what you find on iMessage, WhatsApp, and Facebook Messenger. Encrypted messaging, enhanced media sharing, group chats, and real-time typing indicators are a few of the improvements that come with RCS chat.
Most modern Android phones ship with Google Messages as the default texting app, which includes RCS. You've probably used RCS when texting other Android users with a smartphone for the last few years. The issue comes when texting someone who uses an iPhone. Apple continues to refuse to adopt RCS despite Google's high-pressure RCS shaming campaign. And while a world where Android and iPhone offer a unified messaging experience would be ideal, Apple's hesitation seems justified since it took RCS over a decade to gain traction with carriers and OEMs.
This guide focuses on the Google Messages app, the default on Google Pixel phones, and those from Samsung, OnePlus, Motorola, and others. If your phone doesn't come with Google Messages preinstalled, you can download it. A few regions may not support RCS Chat, but it's available in many of Android's most populous markets.
This guide focuses on the Google Messages app, the default on Google Pixel phones, and those from Samsung, OnePlus, Motorola, and others. If your phone doesn't come with Google Messages preinstalled, you can download it from the Play Store. Although the feature isn't available in every region or on every carrier, Google announced more than 800 million people currently use RCS Messages during its 2023 I/O keynote address.
Most of the time, the Messages app prompts you to activate RCS if you haven't already. If the prompt below shows up, you're ready to set up and use RCS.
You can tell you're sending RCS Chat messages when the input dialog box says Chat message or RCS message. If Google Messages doesn't prompt you to turn on RCS Chat, follow the instructions in the next section to turn it on.
If you're opening the Google Messages app for the first time or resetting your phone, you may need to activate chat features manually.
Even though RCS improves the texting experience, it might not be the preferred solution for everyone. You may want to turn it off if you decide that RCS isn't for you. If you have issues with the connection, turning off the setting and reactivating it might be a good reason to do so.
To turn off the RCS chat features on your device, do the following:
With RCS turned off, the messages you send and receive revert to traditional SMS/MMS text format until you activate RCS again. Turning off RCS before you get a new phone is also advisable to avoid potential messaging issues from the previous device. If you keep your old phone, it's easy to deactivate these settings. If you no longer have access to it, Google has a form you can fill out to deregister your phone number.
To avoid issues, don't turn the chat features off and on multiple times in a short amount of time, as some people have been temporarily blocked from RCS chats when the feature is toggled on and off multiple times. Check out Google's recommendations if you're locked out of RCS.
RCS chat can share high-resolution photos and videos, an improvement over traditional texts. You can also send messages over Wi-Fi and mobile data. You can identify whether someone turned on RCS by checking for a bubble badge on the home screen.
In the RCS chats section of the Settings menu, you'll see more options to enhance your chats:
Google Messages has plenty of built-in features that work without any setup:
There shouldn't be carrier charges when you use RCS chat on Wi-Fi. When you're away from Wi-Fi, the only charge is for mobile data, which is minimal when sending text. Be careful with video sharing if your mobile data plan is limited.
RCS messaging is a step up from regular texting, with features like end-to-end encryption, media sharing, location sharing, and typing indicators. Despite this, Apple continues to snub the RCS standard. However, Google has made it easier than ever for Android users to interact with iMessages.
