What RCS messaging is and why you might want it
RCS (Rich Communication Services) is a texting standard that works over your data connection instead of the older SMS network. It lets you send higher-quality photos, see when someone is typing, know when your message was read, and use group chat features that SMS cannot do. If the person you are texting also has RCS turned on, you get these features automatically — the conversation just upgrades.
RCS is not a separate app you read. It lives inside your phone's default messaging app (the one that handles regular texts). Your carrier or phone manufacturer controls whether RCS is available to you, and you control whether to turn it on. The trade-off is that RCS uses your data plan instead of your SMS allowance, and it sends more information to your carrier and Google than a plain text does.
Whether you want RCS depends on your own comfort with that trade-off. If you text mostly over WiFi anyway, or if you value the read receipts and typing indicators, it is worth turning on. If you prefer to keep your texting as minimal as possible in terms of what your carrier sees, you can leave it off.
Key Takeaways
- RCS turns on in your default messaging app settings, not in a separate place, and the exact steps depend on whether you use Android Messages, Samsung Messages, or another app.
- Your carrier must support RCS for it to work, and not all carriers have rolled it out everywhere yet — you can check your carrier's website to see if it is available in your area.
- RCS only works between two people who both have it turned on; if the other person uses SMS or a different messaging app, the conversation stays as a regular text.
- Turning on RCS means your carrier and Google see more data about your texts than they do with SMS, so weigh that against the features you gain.
How to turn on RCS in Android Messages
If you use Android Messages as your default texting app, RCS is usually the easiest to enable. Open Android Messages, tap the three-line menu icon in the top left, then tap Settings. Look for Advanced or Chat features (the name varies by Android version). You should see a toggle for Enable chat features or RCS. Tap it to turn it on.
The app will then try to register your phone number with Google's RCS network. This can take a few minutes. You will see a message saying "Chat features are on" or "Connecting" while it works. If it gets stuck on "Connecting" for more than five minutes, try turning the toggle off and back on again, or restart your phone.
Once it says "Chat features are on", you are done. You do not need to do anything else. The next time you text someone who also has RCS on, the conversation will show read receipts and typing indicators automatically.
How to turn on RCS in Samsung Messages
Samsung phones often come with Samsung Messages as the default app instead of Android Messages. To turn on RCS here, open Samsung Messages and tap the three-dot menu in the top right. Tap Settings, then Advanced, then look for Chat features or Enable chat features. Tap the toggle to turn it on.
Samsung Messages uses the same Google RCS network as Android Messages, so the registration process is the same — it may take a few minutes, and you will see a status message while it connects. If you have trouble, make sure Samsung Messages is set as your default texting app. Go to Settings > Apps > Default apps > Messages and select Samsung Messages.
Checking whether your carrier supports RCS
RCS only works if your carrier has turned it on in your area. Most major US carriers (Verizon, AT&T, T-Mobile, and US Cellular) now support it, but coverage is still rolling out. The fastest way to check is to visit your carrier's website and search for "RCS" or "chat features".
If your carrier does not support RCS yet, the toggle in your messaging app will either be greyed out or will stay stuck on "Connecting". You cannot turn it on if your carrier has not enabled it on their end. In that case, you can check back in a few months, or contact your carrier's customer service to ask when RCS will be available in your area.
What happens when you text someone without RCS
RCS only works when both people have it turned on. If you text someone who does not have RCS, or who uses a different messaging app like WhatsApp or iMessage, the conversation falls back to regular SMS. You will not see read receipts or typing indicators, and the message will not show as a "chat" in your app.
This happens automatically — you do not have to do anything. Your phone detects whether the other person has RCS and adjusts. So you can have RCS turned on and still text people the old way without any problem.
Understanding the privacy and data trade-offs
RCS sends more information than SMS does. Your carrier can see that you are using RCS, and Google (which runs the RCS network for most phones) can see metadata about your conversations — things like when you sent a message, that it was read, and that someone is typing. With SMS, your carrier sees less of this detail.
This does not mean your messages are less encrypted. RCS messages are encrypted in transit the same way SMS is (which is to say, not very much). But the extra metadata — read receipts, typing indicators, and the fact that you are using RCS at all — is visible to your carrier and to Google.
If you are uncomfortable with that, you can turn RCS off and stick with SMS, or you can use a separate messaging app like Signal or WhatsApp for conversations where you want more privacy. RCS is a middle ground: it gives you better features than SMS without requiring you to switch apps, but it does cost you some privacy compared to SMS.
Troubleshooting RCS that will not turn on
If the toggle stays greyed out or stuck on "Connecting", try these steps in order. First, make sure your phone has a strong data connection — RCS needs either WiFi or mobile data to register. Second, restart your phone. Third, check that your messaging app is up to date by opening the Google Play Store (or Samsung Galaxy Store if you use Samsung Messages), searching for your messaging app, and tapping Update if one is available.
If it still will not connect, your carrier may not support RCS yet in your area. You can also try switching your default messaging app to Android Messages (if you were using something else) and trying again, since Android Messages is the most widely supported. If none of that works, contact your carrier's customer service and ask whether RCS is available on your account and in your area.
Frequently Asked Questions
Does RCS cost extra money?
No. RCS uses your existing data plan, the same way iMessage or WhatsApp does. You do not pay per message. If you have unlimited data, RCS costs you nothing. If you have a limited data plan, RCS messages will count against your data allowance, but the amount is very small — a typical RCS message uses less than 1 KB of data.
Can I turn RCS off if I change my mind?
Yes. Go back to the same settings menu where you turned it on and toggle it off. Your phone will go back to using regular SMS for all texts. You can turn it back on anytime.
Will RCS work if I switch phones?
Yes, as long as your new phone has RCS support and your carrier supports it. When you set up your new phone, RCS will register automatically if you have it turned on. You do not have to do anything special.
Is RCS safer than SMS?
RCS and SMS have similar security — both are encrypted in transit, but both can be read by your carrier and by Google (in RCS's case). Neither is as private as Signal or WhatsApp. RCS is safer than SMS in the sense that it has newer security standards, but the difference is small. If privacy is your main concern, use a dedicated messaging app instead.
What if my carrier uses a different RCS network?
Most US carriers use Google's RCS network, but some older carrier networks exist. If your carrier uses a different one, your messaging app will connect to that network instead. The steps to turn it on are the same, and it works the same way — you just will not see the "Google" branding.
