What happens when you switch from RCS to SMS

RCS (Rich Communication Services) and SMS (Short Message Service) are two different ways your phone sends text messages. RCS is newer and lets you send larger files, see when someone is typing, and use read receipts — but it requires an internet connection and works best between phones on the same carrier or using Google Messages. SMS is the older standard that works on every phone and carrier, uses almost no data, and works even when your internet is down.

Switching from RCS to SMS means your phone will stop trying to send messages through RCS and go back to the basic text message system instead. You will lose typing indicators and read receipts, but your messages will reach more people reliably and work in situations where RCS fails — like in areas with poor data coverage or when texting someone on an older phone.

The steps to make this change depend on which messaging app you use. Most people use either their phone's built-in Messages app or Google Messages. Both let you turn RCS off in settings, though the exact location of that setting differs.

Key Takeaways

  • RCS requires an internet connection and only works reliably between certain phones and carriers, while SMS works on every phone and carrier with just cellular signal.
  • Turning off RCS in your messaging app settings will make your phone send regular text messages instead, which reach more people but lose features like typing indicators.
  • Google Messages and your phone's built-in Messages app have different settings menus, so the steps depend on which app you actually use to text.
  • If RCS keeps turning back on automatically, your carrier or phone manufacturer may have enabled it by default and you may need to disable it in multiple places.

How to turn off RCS in Google Messages

Google Messages is the most common place people encounter RCS, because Google actively pushes RCS through this app. Open Google Messages and look for the three-dot menu icon in the top right corner of the screen. Tap it, then tap Settings.

Inside Settings, look for Advanced or Chat features — the exact name varies by phone and Android version. Tap that section. You will see a toggle or switch labeled Enable chat features or Chat features. Turn this toggle off. Once it is off, Google Messages will stop using RCS and will send regular SMS text messages instead.

After you turn it off, wait a few seconds and check that the toggle stays off. On some phones, the setting resets itself if your carrier has RCS enabled on your account. If the toggle turns back on by itself, your carrier has RCS enabled at their end, and you will need to contact them to disable it on your account — turning it off in the app alone will not be enough.

How to turn off RCS in your phone's built-in Messages app

If you use your phone's default messaging app instead of Google Messages, the process is similar but the menu location is different. Open your Messages app and tap the three-dot menu or settings icon — on most phones this is in the top right, but on some Samsung phones it is at the bottom. Tap Settings.

Look for Chat features, Advanced, or More settings. Tap that section. Find the toggle for Enable chat features, Chat features, or RCS and turn it off. The exact wording depends on your phone manufacturer and Android version, but the toggle itself will be clearly labeled.

If you cannot find this setting in your Messages app, your phone may not support RCS at all, or your carrier may not have enabled it. In that case, your phone is already using SMS and there is nothing to change.

Why RCS keeps turning back on

Some carriers and phone manufacturers enable RCS by default and make it difficult to turn off permanently. If you turn off RCS and it comes back on within hours or days, your carrier has likely enabled it on your account. This happens most often with carriers like T-Mobile, Verizon, and AT&T, which have invested in RCS infrastructure.

To stop RCS from turning back on, you have two options. First, contact your carrier's customer service and ask them to disable RCS on your account. Explain that you want to use SMS only. They can usually do this in their system, and it will prevent RCS from re-enabling itself. Second, if you use Google Messages, you can turn off automatic RCS set up by going to Settings > Advanced and looking for Auto-read MMS or Auto-enable chat features — turn both of these off.

If neither of these steps works, your phone may have RCS enabled at the system level by your manufacturer. In that case, the most reliable solution is to use a different messaging app entirely, such as Signal or WhatsApp, which do not use RCS at all.

What to expect after you switch to SMS

Once RCS is off, your text messages will look and behave differently. You will no longer see typing indicators (the three dots that show someone is typing), and you will not get read receipts (the checkmarks that show someone has read your message). Messages will take slightly longer to send and may not arrive in the exact order you sent them if you send several in quick succession.

File size limits will also change. With RCS, you could send photos and videos up to several megabytes. With SMS, you are limited to smaller file sizes, and your phone will automatically compress large photos before sending them. If you try to send a very large file over SMS, your phone will either shrink it or ask you to use a different method, like email or a cloud service.

The biggest advantage is reliability. SMS works on every phone and every carrier, even in areas with weak data coverage. If you are in a location where your data connection is spotty but you still have cell signal, SMS will work when RCS would fail or time out.

When you might want to keep RCS on instead

RCS is worth keeping on if you text frequently with people on the same carrier and have reliable data coverage. The typing indicators and read receipts make conversations feel more natural, similar to messaging apps like iMessage or WhatsApp. If you are texting someone on a different carrier or an older phone, RCS will automatically fall back to SMS anyway, so turning it on does not hurt compatibility.

RCS also handles group texts better than SMS. With RCS, you can add or remove people from a group conversation after it starts, and everyone sees the same conversation thread. With SMS, group texts can split into separate conversations depending on the phone, and adding people later can be confusing.

The trade-off is that RCS requires an active internet connection. If your data is off or you are in airplane mode, RCS messages will not send at all, whereas SMS will send over cellular signal alone. If you travel frequently or spend time in areas with poor data coverage, SMS is the more reliable choice.

Frequently Asked Questions

Will people know I switched from RCS to SMS?

No. People texting you will not see any notification that you switched. Their messages will arrive as normal SMS texts, and they will not see typing indicators or read receipts from you anymore — but they will not know why. If they are also using RCS, they may notice the change, but most people will not think about it.

Can I turn RCS back on later if I change my mind?

Yes. Go back to your messaging app settings and turn the RCS toggle back on. It will take a few minutes to set up, and you will see typing indicators and read receipts again. If your carrier disabled it on your account, you may need to contact them again to re-enable it.

Does turning off RCS affect my data plan or bill?

No. SMS uses almost no data and does not count against your data limit. RCS uses slightly more data because it sends files over the internet, but the amount is small enough that it will not noticeably affect your bill. Turning RCS off will not save you money.

What if my phone does not have a Messages app settings menu?

Some phones use a messaging app made by the carrier instead of a standard Messages app. If you cannot find RCS settings in your app, try opening your phone's main Settings app, searching for "RCS" or "chat features", and looking for a system-level toggle. If nothing appears, your phone may not support RCS, and you are already using SMS.

Is SMS less find than RCS?

SMS and RCS both send messages over your carrier's network, and neither is encrypted by default. If security is important to you, use an app like Signal or WhatsApp instead, which encrypt messages end-to-end. Turning off RCS does not make SMS less find — they are equally unencrypted.
